Installing Gentoo on a ThinkPad X60 Tablet

2008-05-10T14:08:43Z

Gorillagorillagorilla: /* Gentoo General */ suspend2-sources no longer exist. They are now tuxonice-sources.

= Gentoo General =

Some general apps are needed, these are installed:
emerge thinkpad
echo "thinkpad" >> /etc/modules.autoload.d/kernel-2.6

TODO:
echo "app-laptop/hdapsd" >> /etc/portage/package.keywords
emerge hdapsd app-laptop/tp_smapi
rc-update add hdapsd default
/etc/init.d/hdapsd start

= Sound =
NOTE: If you get an hda_intel probe error on boot, you have to enable modem support in bios (don't ask why!).

In the kernel configuration:
Device Drivers --->
Sound --->
Advanced Linux Sound Architecture --->
PCI devices --->
<*> Intel HD Audio
Now emerge alsa-utils and add alsasound to the default runlevel:
emerge -av alsa-utils
rc-update add alsasound default
/etc/init.d/alsasound start
Unmute the sound using alsamixer by pressing the m key on the Master and PCM sliders (MM=Muted / 00=Not muted)

= Display =
In the kernel configuration:
Device Drivers --->
Character devices --->
<*> Direct Rendering Manager
<*> Intel 830M, 845G, 852GM, 855GM, 865G (i915 driver) --->
Now run xorgcfg which should start smoothly. Do your personal changes (none), and save the files to their default location.
Edit {{path|/etc/X11/xorg.conf}} and add the following lines:
Section "dri"
Mode 0666
EndSection

Now for the rotation to work, we need to emerge some stuff, and make some editing.
First, emerge some apps (note: wee need linuxwacom >= 0.7.8)
echo "x11-drivers/linuxwacom" >> /etc/portage/package.keywords
emerge linuxwacom sudo xhost xrandr

Get the rotate script from ref. A, and make some adjustments:
cd /usr/local/bin
wget http://luke.no-ip.org/x60tablet/examples/rotate
chmod +x rotate
sed "s/cursor/Cursor/" -i rotate
sed "s/stylus/Stylus/" -i rotate
sed "s/eraser/Eraser/" -i rotate
sed 's/"%s set %s Rotate %s"/"sudo su -c \\"DISPLAY=:0.0 %s set %s Rotate %s\\""/' -i rotate
sed "s/'normal': 'NONE', 'left': 'CCW', 'right': 'CW', 'inverted': 'HALF'/'normal': '0', 'left': '2', 'right': '1', 'inverted': '3'/" -i rotate

Put yourself into the wheel group, and setup sudo to make you run xsetwacom without password.

{{HINT|For the compiz-fusion to work you will need to start it like this:
<nowiki>LIBGL_ALWAYS_INDIRECT=true compiz-fusion --replace --indirect-rendering ccp</nowiki>}}

TODO: xhost +

= Input =
== Pen ==
In the kernel configuration:
Device Drivers --->
Input device support --->
<*> Event interface
[*] Miscellaneous devices --->
<*> User level driver support
USB support --->
< > Wacom Intuos/Graphire tablet support

The Wacom Intus/Graphire USB Tablet should not be activated, the X60 Tablet is not an USB device.

Emerge setserial;
emerge setserial
and add the following (magic) line to {{path|/etc/conf.d/local.start}}:
setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig

If you get 'Cannot set serial info: Invalid argument' your kernel may have slightly broken serial support (suspend2-sources-2.6.22-r2, gentoo-sources-2.6.22-r5), this is fixed in gentoo-sources-2.6.22-r9.

{{WARN|Xorg 7.3 works with current linuxwacom (0.7.8-3, 0.7.9-1), but in a strange way. Keep Xorg 7.2 unless you are going to use your pen only as mouse and only in the normal rotation.}}
'''Re to ATTENTION!''' I reply to myself. In the linuxwacom 0.7.8 branch they added the support for the multitouch feature. However this "feature" makes the usage of pen almost impossible (see [http://sourceforge.net/forum/forum.php?thread_id=1777969&forum_id=236872 this forum]). I prepared a patch which removes this feature and wrote an ebuild which can apply this patch: [https://bugs.gentoo.org/show_bug.cgi?id=147537 Bugzilla Bug 147537]. However still I have small problems in Xorg 7.3: [http://sourceforge.net/tracker/index.php?func=detail&aid=1823908&group_id=69596&atid=525124 bug 1823908]

Now add the following lines to your xorgcfg generated {{path|/etc/X11/xorg.conf}}:
Section "InputDevice"
Identifier "Cursor"
Driver "wacom"
Option "Device" "/dev/ttyS0"
Option "Type" "cursor"
Option "ForceDevice" "ISDV4"
EndSection
Section "InputDevice"
Identifier "Stylus"
Driver "wacom"
Option "Device" "/dev/ttyS0"
Option "Type" "stylus"
Option "ForceDevice" "ISDV4"
EndSection
Section "InputDevice"
Identifier "Eraser"
Driver "wacom"
Option "Device" "/dev/ttyS0"
Option "Type" "eraser"
Option "ForceDevice" "ISDV4"
EndSection

And the following three lines in the end of the ServerLayout section:
InputDevice "Cursor" "SendCoreEvents"
InputDevice "Stylus" "SendCoreEvents"
InputDevice "Eraser" "SendCoreEvents"

=== Xournal ===
The ebuild in [http://bugs.gentoo.org/show_bug.cgi?id=143177 Bug 143177] works fine for verion 0.4.1

== Touch Screen ==

It works for me from the box. I just unexpectedly discovered that it works. However in the "left" and "right" rotations of the screen the pointer appears approximately 3cm from the touch point. I do not know how to solve this.

However it causes a lot of problem so I prepared a sollution (see the reply to attention above: [http://www.thinkwiki.org/wiki/installing_Gentoo_on_a_ThinkPad_X60_Tablet#Pen]).

== Trackpoint ==
Works.

== Fingerprint Reader ==
This actually is surprisingly easy to make work:) Just emerge thinkfinger >= 0.3;
echo "sys-auth/thinkfinger" >> /etc/portage/package.keywords
emerge thinkfinger
and add the following line in {{path|/etc/pam.d/system-auth}}:
auth sufficient pam_thinkfinger.so

The first section in the file should now look like the following:
auth required pam_env.so
auth sufficient pam_thinkfinger.so
auth sufficient pam_unix.so try_first_pass likeauth nullok

All left is to read your fingerprint for your user. Run tf-tool --add-user <login>, then reboot and see if it works.
If using gdm, it should work smoothly.

==Thinkpad buttons==
You can enable them in the kernel either built-in or as a module:

Location: │
-> Device Drivers │
-> Character devices
<M> /dev/nvram support

In case you chose the module you will need to autoload it since it is not loaded by the udev:
echo nvram >> /etc/modules.autoload.d/kernel-2.6

By default the /dev/nvram device is configured for root only access. In order to change it permanentely add the corresponding rule to udev. For example I did:
echo "KERNEL==\"nvram\", GROUP=\"users\"" >> /etc/udev/rules.d/50-local.rules

After that you can either configure them using app-laptop/tpb or KDE user can relay on the KMilo application configurable in the
"Control Center -> System Administration -> IBM Thinkpad Laptop".

= Network =
== Ethernet ==
In the kernel configuration:
Device Drivers --->
Network device support --->
Ethernet (1000 Mbit) --->
<*> Intel(R) PRO/1000 Gigabit Ethernet support

Configure the ethernet card in {{path|/etc/conf.d/net}}:
config_eth0="dhcp"
eth0_dhcpcd="-t 4"

== Wireless ==
Note: Make sure that the hardware disable-switch isn't disabled - it is placed at the front/bottom of the laptop (don't make the same mistake as i did!)

In the kernel configuration:
Device Drivers --->
Network device support --->
Wireless LAN (non-hamradio) --->
[*] Wireless LAN drivers (non-hamradio) & Wireless Extensions
Networking --->
<*> Generic IEEE 802.11 Networking Stack
<M> IEEE 802.11i CCMP support
<M> IEEE 802.11i TKIP encryption

Now, emerge ipw3945, wireless-tools > 22 and wpa_supplicant, and add ipw3945d to the default runlevel by issuing:
echo "net-wireless/wireless-tools" >> /etc/portage/package.keywords
emerge ipw3945 wireless-tools wpa_supplicant
rc-update add ipw3945d default
/etc/init.d/ipw3945d start

Configure the wireless card in {{path|/etc/conf.d/net}}:
config_eth1="dhcp"
eth1_dhcpcd="-t 4"
eth1_modules="wpa_supplicant"
wpa_supplicant_eth1="-Dwext"

If you are a kismet user it should be configured as follows in {{path|/etc/kismet.conf}}:
suiduser=<login>
source=ipw3945,eth1,ipw3945

== VPN ==
To come...

== Bluetooth ==
In the kernel configuration:
Networking --->
<*> Bluetooth subsystem support --->
<*> L2CAP protocol support
<*> RFCOMM protocol support
[*] RFCOMM TTY support
Bluetooth device drivers --->
<*> HCI USB driver

Now emerge bluez-utils;
emerge bluez-utils
and configure your display name in the device section in {{path|/etc/bluetooth/hcid.conf}}:
name "Your Displayname"

Now we are ready to start
rc-update add bluetooth default
/etc/init.d/bluetooth start

= External Connections =

= ACPI =
Just emerge the acpi daemon:
emerge acpid
rc-update add acpid default
/etc/init.d/acpid start

= Extra Features =

= History =
5. July - Initial release.

24. July - Added Gentoo General, Sound, Some kernel configuration for the 2.6.21 kernel and new keycodes.

2. September - All sections are has been polished, and should work properly. Only the last ones are missing.
