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.
Shutdown
Currently the system will hang most of the time during shutdown, with the last message on the console being
ip6tables: Unloading modules:
without [Ok] getting printed at the end of the line.
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). Occasional screen corruption can occur, such as a corrupted background image or with the vertical scroll bars (partly green).
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.
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.
| Output | Mode | Result | |
| LVDS+VGA | Boot with display attached | Mirror mode | Plymouth Graphical boot * LVDS shows normal boot at full resolution * VGA no signal GDM * LVDS is switched off * VGA shows out of range error |
| Hotplug | Mirror mode | GDP is not able to activate VGA display VGA display remains black | |
| Hotplug | Extended desktop | horizontal striped background corruption on both displays. GDP windows show normal as does the mouse. Moving windows around clear background corruption, but GDP reverts to previous config because it claims it did not get a reply. | |
| LVDS+DVI | Boot with display attached | Mirror mode | Plymouth Graphical boot * LVDS shows normal boot at full resolution * DVI no signal GDM * LVDS is switched off * DVI shows out of range error |
| Hotplug | Mirror mode | GDP is not able to activate DVI display DVI display remains black | |
| Hotplug | Extended desktop | horizontal striped background corruption on both displays. GDP windows show normal as does the mouse. Moving windows around clear background corruption, but GDP reverts to previous config because it claims it did not get a reply. | |
| S-Video | n/a | n/a | not currently supported in combination with KMS |
In addition the ThinkPad tends to freeze at shutdown/reboot when an external display is attached. Requiring a hard shutdown.
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 | Event | Works | Notes |
| Fn-F3 | lock screen | thinkpad_acpi | HAL | yes | |
| Fn-F4 | suspend | acpi button | HAL | yes | |
| Fn-F5 | wireless | thinkpad_acpi | HAL | no | |
| Fn-F7 | videomode | thinkpad_acpi | HAL | partial | Attempts to cycle through various modes (LVDS only, LVDS+External in mirror, External only, LVDS+External Extended), but causes corruption due to external display problems. Can be associated with gnome-keybinding-properties |
| Fn-F12 | hibernate | acpi button | HAL | 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 | HAL | 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 | HAL | partial | No default action, but can be associated with gnome-keybinding-properties |
| NextTab | Browser Next tab | standard keyboard driver | HAL | yes | |
| PreviousTab | Browser Previous tab | standard keyboard driver | HAL | yes | |
| Power | Power button | acpi button | HAL | yes | Need to press button for ~1 second to trigger event |
| Lid | Lid button | acpi button | HAL | yes | |
| Dock | Dock eject button | acpi dock | unknown | unknown | Should cause udev event |
| Ultrabay | Ultrabay eject switch | acpi dock | udev | no | Causes udev event, but missing handler |
Untested on Fedora 11
Dock eject was not tested, as I only have a port replicator not a dock.
