| Power Management | Software Suspend (hibernate) | unknown | LiveCD does not allow hibernation |
| Suspend to Memory (ACPI sleep) | no | Enters suspend, but display is black on resume. Perhaps a side-effect of LiveCD? | |

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
Kernel
It is recommended to edit /boot/grub/grub.conf and add 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
Basic X server functionality should work out of the box on the ThinkPad LCD (LVDS).
Fedora 11 uses KMS (Kernel Mode Setting) by default, and this causes problems for now with external displays. VGA external displays do not work properly, and can cause severe screen distortion/corruption when an external VGA display is activated.
Even when no external VGA display is attached, xrandr claims a unknown connection with 1024x768, 800x600 and 640x480 modes. When a display is attached this is replaced by the modes from the actual VGA display.
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.
Desktop Effects
'Desktop Effects' (compiz) seems to work
Wireless Network
Both the Intel and Atheros wireless should work out of the box.
I tested the Intel and it worked. Atheros 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 | HAL event | Works | Notes |
| Fn-F3 | lock screen | thinkpad_acpi | yes | yes | |
| Fn-F4 | suspend | acpi button | yes | partial | Key event works, suspend itself does not |
| Fn-F5 | wireless | thinkpad_acpi | yes | no | |
| Fn-F7 | videomode | thinkpad_acpi | yes | partial | causes a brief flash of the display. Can be associated with gnome-keybinding-properties |
| Fn-F9 | undock | acpi button | yes | no | causes event, but does not actually undock |
| Fn-F12 | hibernate | acpi button | yes | partial | does the same as Fn-F4 (suspend), not hibernate |
| 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 | partial | No default action, but 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 | Need to press button for ~1 second to trigger event |
| Lid | Lid button | acpi button | yes | yes | |
| Dock | Dock eject button | - | no | no | |
| Ultrabay | Ultrabay eject switch | acpi dock | no | no | Handled by ACPI dock driver, but does not work |
