=== Wacom Serial Tablet PC Stylus ===
This is a stylus made for tablet PCs by Wacom.
=== Features ===
* Chipset: Wacom
* Serial: irq 5 port 0x0200
</div>
|}

==Linux Support==
The pen is supported by the XFree/Xorg Wacom driver. New tablets also have the [[MultiTouch]] capability. [[MultiTouch]] is experimentally supported presently by the Linux wacom project. The pen works regardless of [[MultiTouch]] support.

==First steps==
Get the [http://linuxwacom.sourceforge.net/index.php/dl linux wacom driver] and install it on your system.

The pen uses serial and appears on some {{path|/dev/ttySnn}} device where <tt>nn</tt> is a number. An easy way to find it is to map {{path|/dev/ttyS0}} to the pen's port and irq. The values can be found under the windows driver properties. Using values from an {{X41T}} 1869-5CU, the command is: {{cmdroot|setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig}} (you need to run this after every suspend/resume cycle).

This may be inserted into startup scripts in {{path|/etc/rc.d/}} or {{path|/etc/rc.local}}

After mapping the pen, you can check its output with {{cmdroot|wacdump -f tpc /dev/ttyS0}}. This will list raw information about the pens position an click status. Hit Ctrl+C to exit wacdump.

==Setting up your Xorg.conf==
Now that you see the pen working correctly you should configure your Xserver to use the stylus. Add the following sections to your xorg.conf:

Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/ttyS0"
Option "Type" "cursor"
Option "ForceDevice" "ISDV4"
Option "Mode" "Absolute"
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/ttyS0"
Option "Type" "stylus"
Option "ForceDevice" "ISDV4"
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "eraser"
Option "Device" "/dev/ttyS0"
Option "Type" "eraser"
Option "ForceDevice" "ISDV4"
EndSection

# support for "touch" (with finger, available on x200t and some x61t)
Section "InputDevice"
Driver "wacom"
Identifier "touch"
Option "Device" "/dev/ttyS0" # SERIAL ONLY
Option "Type" "touch"
Option "ForceDevice" "ISDV4" # Serial Tablet PC ONLY
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Default Screen" 0 0
InputDevice "Configured Mouse" "CorePointer"
InputDevice "cursor" "SendCoreEvents"
InputDevice "stylus" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
#InputDevice "touch" "SendCoreEvents" #Uncomment if you have this feature.
EndSection

Check the wacom driver man page and [http://linuxwacom.sf.net/ website] for other options.

For handwriting recognition using pen you can use [[CellWriter]].

To get the right mouse button to map to the stylus button use this script and run it through .bashrc

#!/bin/bash
xsetwacom set stylus Button1 1
xsetwacom set stylus Button2 3
xsetwacom set stylus Button3 3

==Wacomcpl==
I found it useful to create a .desktop file for launching the wacomcpl program which is used for many user options for the tablet pen.

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=wacomcpl
GenericName=linux wacom config
Comment=linux wacom configuration tool
TryExec=wacomcpl
Exec=wacomcpl
Terminal=false
Categories=System;
Icon=wacomcpl.png

To have your settings restore after logout/suspend/restart you will need to edit {{path|/home/yourusername/.xinitrc}}.
Go to the last line and change

. /etc/X11/xinit/xinitrc

to read as

# . /etc/X11/xinit/xinitrc

Next you need to create a new sessions preference to load the user file.

For Debian [lenny] go to System > Preferences > Sessions.
Add a new startup program and add the command
sh /home/yourusername/.xinitrc
click ok.

For Ubuntu use System > Preferences > Startup Applications.
add the same startup program as above.

==Screen rotation for X41 and X61 tablets==

[http://www.ziva-vatra.com/index.php?aid=56&id=U29mdHdhcmU= ROTgui - Python program for screen rotation].

The above is a simple program that you bind to a key (I bound it to the "rotate" button on the screen) that will let you rotate the screen 4 ways (90, 180, 270 and 0 degrees).

I prefer manually selecting when I want to rotate the screen because I don't want to accidentally rotate it while moving the laptop around.

The site says it's for an X41, but I can confirm that it works on my X61 as well! (Only tried on Ubuntu, but being a Python program, it should work on other OS-es as well).

The code also has a python module, that will allow you to script your own screen control, if you'd rather not use the GUI (or want to use keybindings/write your own interface on top of it).

==xrandr Rotation==

There is work underway to create a [https://code.edge.launchpad.net/~karl.hegbloom/tabuntu/tablet-screen-rotation-support Tablet Screen Rotation Support] package for Ubuntu. Because I can afford only one tablet computer, and since this is relatively new and not many others have put any work into it yet, so far it mainly supports the Lenovo Thinkpad X61 Tablet. The next phase of development involves refactoring in such a way that it can easily be expanded to support other brands and models of tablet computer. The planned mechanism is similar to that used by the scripts in the Debian acpi-support package.

So far, it supports auto-rotation on conversion from laptop to tablet mode, including rebinding the navpad keys and turning the logical orientation of the Wacom tablet to match. It is done as an event called when the X Server has changed it's xRandR orientation. The actual work is carried out by a quick set of shell scripts that can easily be adapted and extended. The idea is that no matter what piece of software actually caused the X Server to rotate, the same things need to happen whenever it does. So the best place to hook in the support event is on an event handler for the RandR Rotate event. The programs and packaging are simple, and the source is available at the URL above. I encourage you to get a copy and learn from it while helping make it work for a new kind of tablet no other developer has created support for yet! If you can write an essay, you can write the necessary program.

Because this ThinkWiki page is one of the sources I drew from when I initially created tablet-screen-rotation-support. The following scripts by Gtx, radix, and Papertiger probably contain some elements in common. --[[User:KarlHegbloom|KarlHegbloom]] 21:55, 9 February 2009 (UTC)

=== xrotate support scripts ===

linuxwacom is very buggy. I needed some time to get the tablet work with "xrandr -r". I use the script below to do screen rotation. copy the source an put it in /usr/local/bin/xrotate. You may change output and devices to fit to you're system (the default values work fine for an x41 tablet)

you can use "xrotate +" to rotate the screen CCW or "xrotate -" to rotate clockwise. use "xrotate x" where x is
* 0 to set rotation to normal
* 1 to set rotation to left
* 2 to set rotation to inverted
* 3 to set rotation to right

=== modified script ===
On my X200 Tablet i have a "invert" tablet button and a "flip" button, so i modified the the script for my needs. This scripts also works with xrandr program version 1.3.2 and xsetwacom 0.10.3 under Debian Testing (Squeeze). You can call the script with "./tablet.sh flip" or "./tablet.sh invert". I mapped these two functions on the hardware buttons. The full Tutorial can be found on my blog: http://dominikschuermann.de/index.php/2010/05/thinkpad-x200-tablet-for-debian-testing/

=== another modified script (X41) ===
I'm using this script to rotate the screen on my X41 (1866-WG4). The rotation is either absolute using the arguments ''normal'', ''inverted'', ''left'' and ''right'' or relative to the current orientation using ''cw'' or ''ccw''.

<pre>
#!/bin/sh

xrandr=normal
wacom=NONE

case "$1" in
normal)
xrandr=normal
wacom=NONE
;;
inverted)
xrandr=inverted
wacom=HALF
;;
right)
xrandr=right
wacom=CW
;;
left)
xrandr=left
wacom=CCW
;;
cw|ccw)
case `xrandr --verbose -q -o normal --dryrun | grep "Current rotation" | sed "s/Current\ rotation\ \-\ //g"` in
normal)
if [ "$1" = "cw" ]; then
xrandr=right
wacom=CW
else
xrandr=left
wacom=CCW
fi
;;
left)
if [ "$1" = "cw" ]; then
xrand=normal
wacom=NONE
else
xrandr=inverted
wacom=HALF
fi
;;
inverted)
if [ "$1" = "cw" ]; then
xrandr=left
wacom=CCW
else
xrandr=right
wacom=CW
fi
;;
right)
if [ "$1" = "cw" ]; then
xrandr=inverted
wacom=HALF
else
xrandr=normal
wacom=NONE
fi
;;
esac
;;
*)
echo "Usage: $0 {normal|left|right|inverted|cw|ccw}"
exit 1
;;
esac

if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set stylus0 Rotate "$wacom"
xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set eraser0 Rotate "$wacom"
exit 0
fi

exit 1
</pre>

You will have to change lines 69 to 73 to suit your configuration. ''LVDS1'' is the laptop screen as returned by xrandr; ''stylus0'', ''cursor0'' and ''eraser0'' are what I have called the wacom devices in my xorg.conf.
The software I'm using on my X41 is the following:

<pre>
$ xrandr -v
xrandr program version 1.3.3
Server reports RandR version 1.3

$ xsetwacom -V
0.10.5
</pre>

I am using the ''intel'' driver for the graphics adapter; unfortunately, display rotation is not possible with the kernel's intel framebuffer driver and Xorg's ''fbdev''. Both xrandr and xsetwacom were installed from debian sid repositories, xsetwacom came with the ''xserver-xorg-input-wacom'' package, not ''wacom-tools''.

=== X41 tablet with UBUNTU 10.10 ===

On my thinkpad X41 tablet with Ubuntu 10.10 i got this message with the previous script:
<pre>
Cannot find device 'stylus0'.
Cannot find device 'cursor0'.
Cannot find device 'eraser0'
</pre>

In order to get it work I had to change this script a little bit (I didn't need to change or create an "xorg.conf" or anything else, I only used this script):

1. Type in a terminal: 'xinput --list':
<pre>
maxi@maxi-ThinkPad-X41-Tablet:~$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=10 [slave pointer (2)]
⎜ ↳ Serial Wacom Tablet eraser id=12 [slave pointer (2)]
⎜ ↳ Serial Wacom Tablet stylus id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=11 [slave keyboard (3)]
maxi@maxi-ThinkPad-X41-Tablet:~$
</pre>
So you know the id numbers of your Eraser (12) and Stylus (13)

2. Modify the script given in this article: Instead of "Eraser" and "Stylus" use your id-numbers:
Change
<pre>
if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set stylus0 Rotate "$wacom"
xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set eraser0 Rotate "$wacom"
exit 0
fi
</pre>

into

<pre>
if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set 13 Rotate "$wacom"
# xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set 12 Rotate "$wacom"
exit 0
fi
</pre>

So in total, you should have the following script saved in a file (for example xrandr in your homefolder /home/"username")

<pre>
#!/bin/sh

xrandr=normal
wacom=NONE

case "$1" in
normal)
xrandr=normal
wacom=NONE
;;
inverted)
xrandr=inverted
wacom=HALF
;;
right)
xrandr=right
wacom=CW
;;
left)
xrandr=left
wacom=CCW
;;
cw|ccw)
case `xrandr --verbose -q -o normal --dryrun | grep "Current rotation" | sed "s/Current\ rotation\ \-\ //g"` in
normal)
if [ "$1" = "cw" ]; then
xrandr=right
wacom=CW
else
xrandr=left
wacom=CCW
fi
;;
left)
if [ "$1" = "cw" ]; then

else

fi
;;
inverted)
if [ "$1" = "cw" ]; then
xrandr=left
wacom=CCW
else
xrandr=right
wacom=CW
fi
;;
right)
if [ "$1" = "cw" ]; then
xrandr=inverted
wacom=HALF
else
xrandr=normal
wacom=NONE
fi
;;
esac
;;
*)
echo "Usage: $0 {normal|left|right|inverted|cw|ccw}"
exit 1
;;
esac

if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set 13 Rotate "$wacom"
# xsetwacom --set cursor Rotate "$wacom"
xsetwacom --set 12 Rotate "$wacom"
exit 0
fi

exit 1
</pre>

After you saved it as "xrandr", open a terminal, go to the folder, in which you saved "xrandr", and type
<pre>
chmod +x xrandr
</pre>
in order to be able to use this script with typing in an terminal
<pre>
./xrandr right
./xrandr normal
</pre>

If you want to easily switch between two orientations, you can use the following script. You can assign this script to the corresponding button on the tablet. It os working on my Thinkpad X61 tablet. If you remove the "yes" after flipflop= the script works as the script above.

=== Wacom Serial Tablet PC Stylus ===
This is a stylus made for tablet PCs by Wacom.
=== Features ===
* Chipset: Wacom
* Serial: irq 5 port 0x0200
</div>
|}

==Linux Support==
The pen is supported by the XFree/Xorg Wacom driver. New tablets also have the [[MultiTouch]] capability. [[MultiTouch]] is experimentally supported presently by the Linux wacom project. The pen works regardless of [[MultiTouch]] support.

==First steps==
Get the [http://linuxwacom.sourceforge.net/index.php/dl linux wacom driver] and install it on your system.

The pen uses serial and appears on some {{path|/dev/ttySnn}} device where <tt>nn</tt> is a number. An easy way to find it is to map {{path|/dev/ttyS0}} to the pen's port and irq. The values can be found under the windows driver properties. Using values from an {{X41T}} 1869-5CU, the command is: {{cmdroot|setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig}} (you need to run this after every suspend/resume cycle).

This may be inserted into startup scripts in {{path|/etc/rc.d/}} or {{path|/etc/rc.local}}

After mapping the pen, you can check its output with {{cmdroot|wacdump -f tpc /dev/ttyS0}}. This will list raw information about the pens position an click status. Hit Ctrl+C to exit wacdump.

==Setting up your Xorg.conf==
Now that you see the pen working correctly you should configure your Xserver to use the stylus. Add the following sections to your xorg.conf:

Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/ttyS0"
Option "Type" "cursor"
Option "ForceDevice" "ISDV4"

Check the wacom driver man page and [http://linuxwacom.sf.net/ website] for other options.

For handwriting recognition using pen you can use [[CellWriter]].

To get the right mouse button to map to the stylus button use this script and run it through .bashrc

#!/bin/bash
xsetwacom set stylus Button1 1
xsetwacom set stylus Button2 3
xsetwacom set stylus Button3 3

==Wacomcpl==
I found it useful to create a .desktop file for launching the wacomcpl program which is used for many user options for the tablet pen.

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=wacomcpl
GenericName=linux wacom config
Comment=linux wacom configuration tool
TryExec=wacomcpl
Exec=wacomcpl

To have your settings restore after logout/suspend/restart you will need to edit {{path|/home/yourusername/.xinitrc}}.
Go to the last line and change

. /etc/X11/xinit/xinitrc

to read as

# . /etc/X11/xinit/xinitrc

Next you need to create a new sessions preference to load the user file.

For Debian [lenny] go to System > Preferences > Sessions.
Add a new startup program and add the command
sh /home/yourusername/.xinitrc
click ok.

For Ubuntu use System > Preferences > Startup Applications.
add the same startup program as above.

==Screen rotation for X41 and X61 tablets==

[http://www.ziva-vatra.com/index.php?aid=56&id=U29mdHdhcmU= ROTgui - Python program for screen rotation].

The above is a simple program that you bind to a key (I bound it to the "rotate" button on the screen) that will let you rotate the screen 4 ways (90, 180, 270 and 0 degrees).

I prefer manually selecting when I want to rotate the screen because I don't want to accidentally rotate it while moving the laptop around.

The site says it's for an X41, but I can confirm that it works on my X61 as well! (Only tried on Ubuntu, but being a Python program, it should work on other OS-es as well).

The code also has a python module, that will allow you to script your own screen control, if you'd rather not use the GUI (or want to use keybindings/write your own interface on top of it).

==xrandr Rotation==

There is work underway to create a [https://code.edge.launchpad.net/~karl.hegbloom/tabuntu/tablet-screen-rotation-support Tablet Screen Rotation Support] package for Ubuntu. Because I can afford only one tablet computer, and since this is relatively new and not many others have put any work into it yet, so far it mainly supports the Lenovo Thinkpad X61 Tablet. The next phase of development involves refactoring in such a way that it can easily be expanded to support other brands and models of tablet computer. The planned mechanism is similar to that used by the scripts in the Debian acpi-support package.

So far, it supports auto-rotation on conversion from laptop to tablet mode, including rebinding the navpad keys and turning the logical orientation of the Wacom tablet to match. It is done as an event called when the X Server has changed it's xRandR orientation. The actual work is carried out by a quick set of shell scripts that can easily be adapted and extended. The idea is that no matter what piece of software actually caused the X Server to rotate, the same things need to happen whenever it does. So the best place to hook in the support event is on an event handler for the RandR Rotate event. The programs and packaging are simple, and the source is available at the URL above. I encourage you to get a copy and learn from it while helping make it work for a new kind of tablet no other developer has created support for yet! If you can write an essay, you can write the necessary program.

Because this ThinkWiki page is one of the sources I drew from when I initially created tablet-screen-rotation-support. The following scripts by Gtx, radix, and Papertiger probably contain some elements in common. --[[User:KarlHegbloom|KarlHegbloom]] 21:55, 9 February 2009 (UTC)

=== xrotate support scripts ===

linuxwacom is very buggy. I needed some time to get the tablet work with "xrandr -r". I use the script below to do screen rotation. copy the source an put it in /usr/local/bin/xrotate. You may change output and devices to fit to you're system (the default values work fine for an x41 tablet)

you can use "xrotate +" to rotate the screen CCW or "xrotate -" to rotate clockwise. use "xrotate x" where x is
* 0 to set rotation to normal
* 1 to set rotation to left
* 2 to set rotation to inverted
* 3 to set rotation to right

=== modified script ===
On my X200 Tablet i have a "invert" tablet button and a "flip" button, so i modified the the script for my needs. This scripts also works with xrandr program version 1.3.2 and xsetwacom 0.10.3 under Debian Testing (Squeeze). You can call the script with "./tablet.sh flip" or "./tablet.sh invert". I mapped these two functions on the hardware buttons. The full Tutorial can be found on my blog: http://dominikschuermann.de/index.php/2010/05/thinkpad-x200-tablet-for-debian-testing/

=== another modified script (X41) ===
I'm using this script to rotate the screen on my X41 (1866-WG4). The rotation is either absolute using the arguments ''normal'', ''inverted'', ''left'' and ''right'' or relative to the current orientation using ''cw'' or ''ccw''.

<pre>
#!/bin/sh

if [ "$1" = "cw" ]; then

echo "Usage: $0 {normal|left|right|inverted|cw|ccw}"
exit 1
;;
esac

if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set stylus0 Rotate "$wacom"
xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set eraser0 Rotate "$wacom"
exit 0
fi

exit 1
</pre>

You will have to change lines 69 to 73 to suit your configuration. ''LVDS1'' is the laptop screen as returned by xrandr; ''stylus0'', ''cursor0'' and ''eraser0'' are what I have called the wacom devices in my xorg.conf.
The software I'm using on my X41 is the following:

<pre>
$ xrandr -v
xrandr program version 1.3.3
Server reports RandR version 1.3

$ xsetwacom -V
0.10.5
</pre>

I am using the ''intel'' driver for the graphics adapter; unfortunately, display rotation is not possible with the kernel's intel framebuffer driver and Xorg's ''fbdev''. Both xrandr and xsetwacom were installed from debian sid repositories, xsetwacom came with the ''xserver-xorg-input-wacom'' package, not ''wacom-tools''.

=== X41 tablet with UBUNTU 10.10 ===

On my thinkpad X41 tablet with Ubuntu 10.10 i got this message with the previous script:
<pre>
Cannot find device 'stylus0'.
Cannot find device 'cursor0'.
Cannot find device 'eraser0'
</pre>

In order to get it work I had to change this script a little bit (I didn't need to change or create an "xorg.conf" or anything else, I only used this script):

1. Type in a terminal: 'xinput --list':
<pre>
maxi@maxi-ThinkPad-X41-Tablet:~$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=10 [slave pointer (2)]
⎜ ↳ Serial Wacom Tablet eraser id=12 [slave pointer (2)]
⎜ ↳ Serial Wacom Tablet stylus id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=11 [slave keyboard (3)]
maxi@maxi-ThinkPad-X41-Tablet:~$
</pre>
So you know the id numbers of your Eraser (12) and Stylus (13)

2. Modify the script given in this article: Instead of "Eraser" and "Stylus" use your id-numbers:
Change
<pre>
if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set stylus0 Rotate "$wacom"
xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set eraser0 Rotate "$wacom"
exit 0
fi
</pre>

into

<pre>
if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set 13 Rotate "$wacom"
# xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set 12 Rotate "$wacom"
exit 0
fi
</pre>

So in total, you should have the following script saved in a file (for example xrandr in your homefolder /home/"username")

<pre>
#!/bin/sh

xrandr=normal
wacom=NONE

case "$1" in
normal)
xrandr=normal
wacom=NONE
;;
inverted)
xrandr=inverted
wacom=HALF
;;
right)
xrandr=right
wacom=CW
;;
left)
xrandr=left
wacom=CCW
;;
cw|ccw)
case `xrandr --verbose -q -o normal --dryrun | grep "Current rotation" | sed "s/Current\ rotation\ \-\ //g"` in
normal)
if [ "$1" = "cw" ]; then
xrandr=right
wacom=CW
else
xrandr=left
wacom=CCW
fi
;;
left)
if [ "$1" = "cw" ]; then
xrand=normal
wacom=NONE
else
xrandr=inverted
wacom=HALF
fi
;;
inverted)
if [ "$1" = "cw" ]; then
xrandr=left
wacom=CCW
else
xrandr=right
wacom=CW
fi
;;
right)
if [ "$1" = "cw" ]; then
xrandr=inverted
wacom=HALF
else
xrandr=normal
wacom=NONE
fi
;;
esac
;;
*)
echo "Usage: $0 {normal|left|right|inverted|cw|ccw}"
exit 1
;;
esac

if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set 13 Rotate "$wacom"
# xsetwacom --set cursor Rotate "$wacom"
xsetwacom --set 12 Rotate "$wacom"
exit 0
fi

exit 1
</pre>

After you saved it as "xrandr", open a terminal, go to the folder, in which you saved "xrandr", and type
<pre>
chmod +x xrandr
</pre>
in order to be able to use this script with typing in an terminal
<pre>
./xrandr right
./xrandr normal
</pre>

=== Wacom Serial Tablet PC Stylus ===
This is a stylus made for tablet PCs by Wacom.
=== Features ===
* Chipset: Wacom
* Serial: irq 5 port 0x0200
</div>
|}

==Linux Support==
The pen is supported by the XFree/Xorg Wacom driver. New tablets also have the [[MultiTouch]] capability. [[MultiTouch]] is experimentally supported presently by the Linux wacom project. The pen works regardless of [[MultiTouch]] support.

==First steps==
Get the [http://linuxwacom.sourceforge.net/index.php/dl linux wacom driver] and install it on your system.

The pen uses serial and appears on some {{path|/dev/ttySnn}} device where <tt>nn</tt> is a number. An easy way to find it is to map {{path|/dev/ttyS0}} to the pen's port and irq. The values can be found under the windows driver properties. Using values from an {{X41T}} 1869-5CU, the command is: {{cmdroot|setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig}} (you need to run this after every suspend/resume cycle).

This may be inserted into startup scripts in {{path|/etc/rc.d/}} or {{path|/etc/rc.local}}

After mapping the pen, you can check its output with {{cmdroot|wacdump -f tpc /dev/ttyS0}}. This will list raw information about the pens position an click status. Hit Ctrl+C to exit wacdump.

==Setting up your Xorg.conf==
Now that you see the pen working correctly you should configure your Xserver to use the stylus. Add the following sections to your xorg.conf:

Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/ttyS0"
Option "Type" "cursor"
Option "ForceDevice" "ISDV4"
Option "Mode" "Absolute"
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/ttyS0"
Option "Type" "stylus"
Option "ForceDevice" "ISDV4"
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "eraser"
Option "Device" "/dev/ttyS0"
Option "Type" "eraser"
Option "ForceDevice" "ISDV4"
EndSection

# support for "touch" (with finger, available on x200t and some x61t)
Section "InputDevice"
Driver "wacom"
Identifier "touch"
Option "Device" "/dev/ttyS0" # SERIAL ONLY
Option "Type" "touch"
Option "ForceDevice" "ISDV4" # Serial Tablet PC ONLY
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Default Screen" 0 0
InputDevice "Configured Mouse" "CorePointer"
InputDevice "cursor" "SendCoreEvents"
InputDevice "stylus" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
#InputDevice "touch" "SendCoreEvents" #Uncomment if you have this feature.
EndSection

Check the wacom driver man page and [http://linuxwacom.sf.net/ website] for other options.

For handwriting recognition using pen you can use [[CellWriter]].

To get the right mouse button to map to the stylus button use this script and run it through .bashrc

#!/bin/bash
xsetwacom set stylus Button1 1
xsetwacom set stylus Button2 3
xsetwacom set stylus Button3 3

==Wacomcpl==
I found it useful to create a .desktop file for launching the wacomcpl program which is used for many user options for the tablet pen.

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=wacomcpl
GenericName=linux wacom config
Comment=linux wacom configuration tool
TryExec=wacomcpl
Exec=wacomcpl
Terminal=false

To have your settings restore after logout/suspend/restart you will need to edit {{path|/home/yourusername/.xinitrc}}.
Go to the last line and change

. /etc/X11/xinit/xinitrc

to read as

# . /etc/X11/xinit/xinitrc

Next you need to create a new sessions preference to load the user file.

For Debian [lenny] go to System > Preferences > Sessions.
Add a new startup program and add the command
sh /home/yourusername/.xinitrc
click ok.

For Ubuntu use System > Preferences > Startup Applications.
add the same startup program as above.

==xrandr Rotation==

There is work underway to create a [https://code.edge.launchpad.net/~karl.hegbloom/tabuntu/tablet-screen-rotation-support Tablet Screen Rotation Support] package for Ubuntu. Because I can afford only one tablet computer, and since this is relatively new and not many others have put any work into it yet, so far it mainly supports the Lenovo Thinkpad X61 Tablet. The next phase of development involves refactoring in such a way that it can easily be expanded to support other brands and models of tablet computer. The planned mechanism is similar to that used by the scripts in the Debian acpi-support package.

So far, it supports auto-rotation on conversion from laptop to tablet mode, including rebinding the navpad keys and turning the logical orientation of the Wacom tablet to match. It is done as an event called when the X Server has changed it's xRandR orientation. The actual work is carried out by a quick set of shell scripts that can easily be adapted and extended. The idea is that no matter what piece of software actually caused the X Server to rotate, the same things need to happen whenever it does. So the best place to hook in the support event is on an event handler for the RandR Rotate event. The programs and packaging are simple, and the source is available at the URL above. I encourage you to get a copy and learn from it while helping make it work for a new kind of tablet no other developer has created support for yet! If you can write an essay, you can write the necessary program.

Because this ThinkWiki page is one of the sources I drew from when I initially created tablet-screen-rotation-support. The following scripts by Gtx, radix, and Papertiger probably contain some elements in common. --[[User:KarlHegbloom|KarlHegbloom]] 21:55, 9 February 2009 (UTC)

=== xrotate support scripts ===

linuxwacom is very buggy. I needed some time to get the tablet work with "xrandr -r". I use the script below to do screen rotation. copy the source an put it in /usr/local/bin/xrotate. You may change output and devices to fit to you're system (the default values work fine for an x41 tablet)

you can use "xrotate +" to rotate the screen CCW or "xrotate -" to rotate clockwise. use "xrotate x" where x is
* 0 to set rotation to normal
* 1 to set rotation to left
* 2 to set rotation to inverted
* 3 to set rotation to right

=== modified script ===
On my X200 Tablet i have a "invert" tablet button and a "flip" button, so i modified the the script for my needs. This scripts also works with xrandr program version 1.3.2 and xsetwacom 0.10.3 under Debian Testing (Squeeze). You can call the script with "./tablet.sh flip" or "./tablet.sh invert". I mapped these two functions on the hardware buttons. The full Tutorial can be found on my blog: http://dominikschuermann.de/index.php/2010/05/thinkpad-x200-tablet-for-debian-testing/

=== another modified script (X41) ===
I'm using this script to rotate the screen on my X41 (1866-WG4). The rotation is either absolute using the arguments ''normal'', ''inverted'', ''left'' and ''right'' or relative to the current orientation using ''cw'' or ''ccw''.

<pre>
#!/bin/sh

xrandr=normal
wacom=NONE

case "$1" in
normal)
xrandr=normal
wacom=NONE
;;
inverted)
xrandr=inverted
wacom=HALF
;;
right)
xrandr=right
wacom=CW
;;
left)
xrandr=left
wacom=CCW
;;
cw|ccw)
case `xrandr --verbose -q -o normal --dryrun | grep "Current rotation" | sed "s/Current\ rotation\ \-\ //g"` in
normal)
if [ "$1" = "cw" ]; then
xrandr=right
wacom=CW
else
xrandr=left
wacom=CCW
fi
;;
left)
if [ "$1" = "cw" ]; then
xrand=normal
wacom=NONE
else
xrandr=inverted
wacom=HALF
fi
;;
inverted)
if [ "$1" = "cw" ]; then
xrandr=left
wacom=CCW
else
xrandr=right
wacom=CW
fi
;;
right)
if [ "$1" = "cw" ]; then
xrandr=inverted
wacom=HALF
else
xrandr=normal
wacom=NONE
fi
;;
esac
;;
*)
echo "Usage: $0 {normal|left|right|inverted|cw|ccw}"
exit 1
;;
esac

if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set stylus0 Rotate "$wacom"
xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set eraser0 Rotate "$wacom"
exit 0
fi

exit 1
</pre>

You will have to change lines 69 to 73 to suit your configuration. ''LVDS1'' is the laptop screen as returned by xrandr; ''stylus0'', ''cursor0'' and ''eraser0'' are what I have called the wacom devices in my xorg.conf.
The software I'm using on my X41 is the following:

<pre>
$ xrandr -v
xrandr program version 1.3.3
Server reports RandR version 1.3

$ xsetwacom -V
0.10.5
</pre>

I am using the ''intel'' driver for the graphics adapter; unfortunately, display rotation is not possible with the kernel's intel framebuffer driver and Xorg's ''fbdev''. Both xrandr and xsetwacom were installed from debian sid repositories, xsetwacom came with the ''xserver-xorg-input-wacom'' package, not ''wacom-tools''.

=== X41 tablet with UBUNTU 10.10 ===

On my thinkpad X41 tablet with Ubuntu 10.10 i got this message with the previous script:
<pre>
Cannot find device 'stylus0'.
Cannot find device 'cursor0'.
Cannot find device 'eraser0'
</pre>

In order to get it work I had to change this script a little bit (I didn't need to change or create an "xorg.conf" or anything else, I only used this script):

1. Type in a terminal: 'xinput --list':
<pre>
maxi@maxi-ThinkPad-X41-Tablet:~$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=10 [slave pointer (2)]
⎜ ↳ Serial Wacom Tablet eraser id=12 [slave pointer (2)]
⎜ ↳ Serial Wacom Tablet stylus id=13 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=11 [slave keyboard (3)]
maxi@maxi-ThinkPad-X41-Tablet:~$
</pre>
So you know the id numbers of your Eraser (12) and Stylus (13)

2. Modify the script given in this article: Instead of "Eraser" and "Stylus" use your id-numbers:
Change
<pre>
if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set stylus0 Rotate "$wacom"
xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set eraser0 Rotate "$wacom"
exit 0
fi
</pre>

into

<pre>
if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set 13 Rotate "$wacom"
# xsetwacom --set cursor0 Rotate "$wacom"
xsetwacom --set 12 Rotate "$wacom"
exit 0
fi
</pre>

So in total, you should have the following script saved in a file (for example xrandr in your homefolder /home/"username")

<pre>
#!/bin/sh

xrandr=normal
wacom=NONE

case "$1" in
normal)
xrandr=normal
wacom=NONE
;;
inverted)
xrandr=inverted
wacom=HALF
;;
right)
xrandr=right
wacom=CW
;;
left)
xrandr=left
wacom=CCW
;;
cw|ccw)
case `xrandr --verbose -q -o normal --dryrun | grep "Current rotation" | sed "s/Current\ rotation\ \-\ //g"` in
normal)
if [ "$1" = "cw" ]; then
xrandr=right
wacom=CW
else
xrandr=left
wacom=CCW
fi
;;
left)
if [ "$1" = "cw" ]; then
xrand=normal
wacom=NONE
else
xrandr=inverted
wacom=HALF
fi
;;
inverted)
if [ "$1" = "cw" ]; then
xrandr=left
wacom=CCW
else
xrandr=right
wacom=CW
fi
;;
right)
if [ "$1" = "cw" ]; then
xrandr=inverted
wacom=HALF
else
xrandr=normal
wacom=NONE
fi
;;
esac
;;
*)
echo "Usage: $0 {normal|left|right|inverted|cw|ccw}"
exit 1
;;
esac

if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set 13 Rotate "$wacom"
# xsetwacom --set cursor Rotate "$wacom"
xsetwacom --set 12 Rotate "$wacom"
exit 0
fi

exit 1
</pre>

After you saved it as "xrandr", open a terminal, go to the folder, in which you saved "xrandr", and type
<pre>
chmod +x xrandr
</pre>
in order to be able to use this script with typing in an terminal
<pre>
./xrandr right
./xrandr normal
</pre>

If you want to easily switch between two orientations, you can use the following script. You can assign this script to the corresponding button on the tablet. It os working on my Thinkpad X61 tablet. If you remove the "yes" after flipflop= the script works as the script above.

echo $flipflop
if [ -z $flipflop ]; then
# only if variable flipflop is not set
echo "Usage: $0 {normal|left|right|inverted|cw|ccw}"
exit 1

;;
esac

if xrandr --output LVDS1 --rotate "$xrandr"; then
xsetwacom --set 13 Rotate "$wacom"
# xsetwacom --set cursor Rotate "$wacom"

exit 0

exit 1

Dcjfm: /* Working memory configurations */

Some ThinkPads are known to support more memory than their specs say. This page gathers information about those models, how much memory they can take and what special requirements that memory must fulfill.

Have a look at the [[Memory]] page for the official memory configs and partnumbers

==Working memory configurations==
The following table gives an overview of tested memory configurations that exceed the specified limits for that ThinkPad type.
