Game dev: added a little info and structure

{{Stub}}
== Introduction ==

KMilo is a KDE plugin providing binding for some special Thinkpad keys. It is a KDE port of [[tpb]].

== Installing KMilo ==
=== Gentoo ===
KMilo is available in Portage.

emerge kmilo -av

== Usage ==
After installing an entry called "IBM Thinkpad Laptop" will appear in your KDE Control Center under "System Administration".
This lets you choose the program to execute for each event.

You can use appropriate commands to [[How to inject fake keystrokes|inject fake keystrokes]].

Game dev: Added T60p to Model-specific Status

===Software Suspend 2 - swsusp2===
Software Suspend 2, sometimes also called "swsusp2" and "suspend2", is an implementation of suspend-to-disk functionality in the form of a Linux kernel patch and several userspace utilities. It is an alternative to both the BIOS-driven hibernation feature found on most ThinkPad models, and the [[swsusp]] "software suspend" functionality built into recent Linux kernels.
|}

==Features==
Compared to the alternatives, Software Suspend 2 has some unique [http://suspend2.net/features features]:
* Saving the memory image into a swap file, a swap partition or normal a file on any filesystem.
* Cancelling a suspend in progress.
* Different bugs -- if the alternatives don't work, try this one!

It also have the following advantages over [[swsusp]] (these features are also provided, in principle, by the not-yet-stable [[uswsusp]]):
* The ability to compress the memory image as it is written to disk, thereby reducing suspend and resume times.
* Control over amount of RAM written to disk -- can (optionally) discard cached disk blocks to reduce suspend and resume times.
* Textual and graphical UI (optional).

Since it is implemented purely in software, Software Suspend 2 is in principle machine-independent and should work on all modern ThinkPad models. However, in some cases problematic drivers need to be unloaded before suspension. This is handled by the <tt>hibernate</tt> script (see below).

==Installation Instructions==
The [http://suspend2.net/ project home page] has a detailed HOWTO and FAQ. The following are just a few highlights.

===Patching mkinitrd===
If your systems uses an <tt>initrd</tt> file (most do), you'll need to patch or replace your <tt>initrd</tt>-creation script.

*{{Fedora}} 4: in {{path|/sbin/mkinitrd}}, find this line:
echo "echo Mounted /proc filesystem" >> $RCFILE
and add the following immediately afterwards:
echo "echo > /sys/power/suspend2/do_resume" >>$RCFILE
*{{Fedora}} 5: in {{path|/sbin/mkinitrd}}, find this line:
if [ -z "$noresume" -a -n "$swsuspdev" ]; then
and add the following immediately ''before'' the above:
emit "echo 1 > /sys/power/suspend2/do_resume"
You can also use the [http://atrpms.net/dist/fc5/mkinitrd-suspend2/ mkinitrd-suspend2] package from atrpms.
*{{Debian}}: copy [http://dagobah.ucc.asn.au/swsusp/2.0.0.102/swsusp-initrd.sh swsusp-initrd.sh] script to your {{path|/etc/mkinitrd/scripts}} directory before creating initrd image.

Make sure you regenerate your <tt>initrd</tt> file (using <tt>mkinitrd</tt> or by reinstalling the kernel) after patching <tt>mkinitrd</tt>.

===Hibernate script===
Software Suspend 2 works best with the <tt>hibernate</tt> script (available from the project home page), which takes care of auxiliary tasks needed on many systems (e.g., unloading problematic modules and restoring video modes).

====Availability====
*{{Gentoo}}: emerge hibernate-script
*{{Fedora}}: kernel and hibernate RPMs are available at http://mhensler.de/swsusp/
*{{Ubuntu}}: packages for Ubuntu Dapper Drake (kernel, hibernate, suspend2ui-userui): http://dagobah.ucc.asn.au/dapper-kernels/
*{{Ubuntu}}: experimental packages for Ubuntu Edgy Eft (kernel, hibernate, suspend2ui-userui): http://3v1n0.tuxfamily.org/dists/edgy/suspend2/
*PLD: poldek -iv hibernate
*Other: check the home page for packages (deb, i386 rpm, tgz, and source rpm) from http://www.suspend2.net

==Configuration tips==
===RediSafe-like functionality===
The hibernate functionality on some ThinkPad BIOSes offers the useful "RediSafe" feature, which suspends to both RAM and disk. This way you get quick resumes (directly from RAM), plus the safey of suspend-to-disk in case the battery runs out.

Software Suspend 2 provides this feature too; simply add the following to {{path|/etc/hibernate/suspend2.conf}}:

Game dev: patch included in mainline kernel

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;" | [[Image:ultranav.jpg|IBM UltraNav]]
|style="vertical-align:top" |
<div style="margin: 0; margin-right:10px; border: 1px solid #dfdfdf; padding: 0em 1em 1em 1em; background-color:#F8F8FF; align:right;">
===IBM UltraNav===
The classic integrated pointing device in ThinkPads was always a trackpoint. With the T30 IBM introduced UltraNav, a combination of both the classical [[TrackPoint]] coupled with a programmable touchpad. The technology for this combined pointing device comes from Synaptics. The TouchPad features all kind of customizable ways of input, from standard pointing over scrolling by movement along the edges, tap zones, to ignoring accidential touches.
</div>
|}

==Linux Support==
Both the TrackPoint and the TouchPad work with the standard ps2/psaux driver of linux kernels.

To get advanced configurability for the touchpad working there are several drivers for Synaptics TouchPads available for X:
*[[Synaptics TouchPad driver for X]] is an X input driver
*[[tpconfig]] is a tool to configure the TouchPad device before the actual input driver takes over

To get advanced configurability for the TrackPoint, look at the [[Patch to enable advanced trackpoint configuration | TrackPoint kernel patch]]. (Since 2.6.14-rc5 this patch is included in the mainline kernel)

==Windows Support==
The UltraNav driver from IBM is based on the Synaptics driver. It contains a bug leading to "defective pixels":
If the scroll-function of the touchpad is used (moving finger on right border of touchpad), often taskmanger shows
an application/window on its first tab named "Syn Visual Window". Sometimes this stays on the screen and in task
manager. It is a 1x1 pixel large window that is usually white. If you move the mouse directly over this pixel,
a little icon appears like if the middle trackpoint button is used to scroll.
This pixel can be removed by terminating SynTP* processes in taskmanager. Some claim that it can be removed by
using the middle trackpoint button, althought this is not always the case.
So far this problem has been reproduced on T60P and T41P, but only by scrolling large wegpages in Firefox.
After Firefox was closed, the pixel is still there.
IBM was able to reproduce this by installing Firefox on a fresh recovery image in their labs. But they
refuse to fix this or pass it to Synaptics or their driver developers, because Firefox "is not supported".
Guess IBM only wants you to use IE.
This bug is quite annoying because people think it's a wandering defective pixel
