= Tested and Verified on Fedora 13 =

Information in this section has been tested and verified using Fedora 13.

== Installation ==

Installation is straight forward, but you should do so without any external displays attached; you can follow the generic Fedora install instructions.

== Configuration ==
=== Kernel ===
It is recommended to edit {{path|/boot/grub/grub.conf}} and add {{bootparm|hpet|force}} to the kernel line. This will activate HPET (High Precision Event Timer), which will allow the CPU to sleep for longer periods and save power.
=== X Server - ATI RV250===
Out of the box external displays (VGA or DVI) should work, and you can switch display modes with the Fn-F7 key combination.

The following issues still exist for single-head (LVDS only) setups
* unknown physical LVDS display size (0mm x 0mm) reported by RandR

And for Multihead or External displays. Some of these issues are likely caused by the limited amount of VRAM available (32MB)
* S-Video output is distorted [https://bugzilla.redhat.com/show_bug.cgi?id=497055 Bugzilla]
* Multihead causes the desktop to become very slow
* Screen rotation does not work in combination with Multihead
* Compiz does not work in combination with Multihead [https://bugzilla.redhat.com/show_bug.cgi?id=560048 Bugzilla]
* external ONLY does not work (both displays are black)
* Metacity Compositing does not work with Multihead
* Strangely enough, plymouth gives a high-res text mode during boot with single-head, but graphical mode with Multihead boot

=== WiFi ===
Both the Intel and Atheros AR5212 wireless should work out of the box.

Intel WiFi was not tested.

===Audio===
Starting with the 2.6.33 kernel, as included with Fedora 13, the [[thinkpad-acpi|thinkpad_acpi]] driver now exports a volume control to ALSA, which represents the volume and mute buttons on the ThinkPad keyboard. Unfortunately for ALSA/PulseAudio this is just another volume control (one without actual inputs/outputs), and as such there is no effective end-user change from what you had with previous kernels.

This volume control can be seen by running {{cmd|alsamixer|}}, pressing F6 and selecting ''ThinkPad Console Audio Control''

=== ThinkPad Extra keys ===
ThinkPad keys are handled by a mixture of the thinkpad_acpi, acpi button and acpi dock drivers.

|-
|}

=== Ultrabay ===
Ultrabay eject is not handled properly by default. Since there is no undock udev handler. This udev rule and eject script works for me: [[How to hotswap Ultrabay devices]]

===IrDA===
IrDA is detected, but does not work. Part of the problem is that the default Fedora configuration expects to find the IrDA port at /dev/ttyS2, while it should use /dev/ircomm0 instead. This can be fixed in {{path|/etc/sysconfig/irda}} after which the irda service can be started ({{cmdroot|service irda start}}).

However, even after this communication with other devices fails. irdadump does not show any output when something like a mobile phone with IrDA is sending data.

= Untested on Fedora 13 =
The following features where not tested with Fedora 13. If you have tested them, please update the table
* Intel WiFi
* Parallel port
* Dock eject
* TPM
