Tested and Verified on Fedora 11
Information in this section has been tested and verified using Fedora 11.
Installation
Installation is straight forward; you can follow the generic Fedora install instructions.
Configuration
X Server
Basic X server functionality should work out of the box on the ThinkPad LCD (LVDS), as long as no external displays are attached at boot. Occasional screen corruption can occur, such as a corrupted background image or with the vertical scroll bars.
Fedora 11 uses KMS (Kernel Mode Setting) by default, and this causes problems for now with external displays. Neither VGA or DVI external displays work properly, and can cause severe screen distortion when booting with an external VGA display attached.
On the up side, with KMS the maximum virtual display size is now 4096x4096 (2048x2048 without KMS), which should allow extended desktop once the issues with external display support are sorted.
Also, with KMS Svideo output is not supported for now.
These issues have been reported to Red Hat bugzilla.
Desktop Effects
Enabling 'Desktop Effects' (compiz) cause the Xserver to restart
Wireless Network
Both the Intel and Atheros wireless should work out of the box.
I tested the Atheros and it worked. Intel was not tested.
ThinkPad keys
ThinkPad keys are handled by a mixture of the thinkpad_acpi, acpi button and acpi dock drivers.
| Key | Function | Handled by | Seen by HAL | Works | Notes |
| Fn-F3 | lock screen | thinkpad_acpi | yes | yes | |
| Fn-F4 | suspend | acpi button | yes | yes | |
| Fn-F5 | wireless | thinkpad_acpi | yes | no | |
| Fn-F7 | videomode | thinkpad_acpi | yes | no | causes a brief flash of the display. Can be associated with gnome-keybinding-properties |
| Fn-F12 | hibernate | acpi button | yes | yes | |
| Fn-Home | brightness up | - | no | yes | changing thinkpad_acpi hotkey_mask, causes HAL events. But sysfs backlight brightness value does not change, so OSD is wrong. |
| Fn-End | brightness down | - | no | yes | changing thinkpad_acpi hotkey_mask, causes HAL events. But sysfs backlight brightness value does not change, so OSD is wrong. |
| Fn-PgUp | thinklight | - | no | yes | changing thinkpad_acpi hotkey_mask, causes HAL events. No OSD in any case. |
| Fn-Space | zoom | thinkpad_acpi | yes | no | |
| VolumeUp | Volume Up | - | no | yes | changing thinkpad_acpi hotkey_mask, causes HAL events. But OSD is wrong |
| VolumeDown | Volume Down | - | no | yes | changing thinkpad_acpi hotkey_mask, causes HAL events. But OSD is wrong |
| Mute | Mute | - | no | yes | changing thinkpad_acpi hotkey_mask, causes HAL events and OSD. works as a on/off toggle |
| Access IBM | Vendor key | thinkpad_acpi | yes | no | can be associated with gnome-keybinding-properties |
| NextTab | Browser Next tab | standard keyboard driver | yes | yes | |
| PreviousTab | Browser Previous tab | standard keyboard driver | yes | yes | |
| Power | Power button | acpi button | yes | yes | |
| Lid | Lid button | acpi button | yes | yes | |
| Dock | Dock eject button | acpi dock | unknown | unknown | Should be handled by ACPI dock driver |
| Ultrabay | Ultrabay eject switch | acpi dock | no | no | Handled by ACPI dock driver, but does not work |
Due to Xorg limitations, some keys that cause HAL events work with Xorg (Access IBM and Fn-F7) and others do not. This is a known limitation that should be fixed with the next major Xorg (v1.7) release.
