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 /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 - ATI RV250
Out of the box external displays (VGA, DVI or S-Video) do not work properly. It is best to do the install without any external displays attached. After the install is finished you should install the available updates, in particular the available Xorg, libdrm, Mesa and Kernel updates.
Unfortunately the latest ATI Radeon driver and kernel are not yet available in the Updates repository, so for the time being do the following;
yum update kernel\* libdrm mesa\* plymouth\* xorg\* --enablerepo=updates-testing
After the updates are installed, external VGA and DVI displays should work and you can switch display modes with the Fn-F7 key combination to switch between different modes.
The updates will also improve S-Video support, and give you the ability to select TV output mode (PAL, NTSC, etc) with xrandr
. Unfortunately the output is still distorted. See the Bugzilla report for more information.
In addition the following issues exist
- unknown physical LVDS display size (0mm x 0mm)
- nasty LVDS 'flash' when hotplugging an external display and running xrandr
- external ONLY does not work (both displays are black)
- r200_run_tcl_render error with some OpenGL apps (e.g. Extreme TuxRacer) [1]
WiFi
Both the Intel and Atheros AR5212 wireless should work out of the box.
I did limited tested with Atheros and it seemed to worked as long as your not too far from your WiFi AP/Router. The further away you are the more problems, ranging from several tries before it connects, to never connecting even though it reports 2 out of 4 bars in signal strength. Once connected you can move further away and keep connected, at least until it needs to re-negotiate at which time you loose your connection.
Intel WiFi was not tested.
Audio
Starting with the 2.6.33 kernel, as included with Fedora 13, the 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 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.
Key | Function | Handled by | Event | Works | Notes |
Fn-F3 | lock screen | thinkpad_acpi | HAL | yes | |
Fn-F4 | suspend | acpi button | HAL | partial | button works, but suspend fails on resume with corrupted display |
Fn-F5 | wireless | thinkpad_acpi | HAL | partial | Works as a radio kill switch, kills WiFi but not Bluetooth |
Fn-F7 | videomode | thinkpad_acpi | HAL | no | No longer has any effect! Regression. |
Fn-F12 | hibernate | acpi button | HAL | yes | |
Fn-Home | brightness up | - | no | yes | no default OSD. Install the tpb rpm as a workaround. |
Fn-End | brightness down | - | no | yes | no default OSD. Install the tpb rpm as a workaround. |
Fn-PgUp | thinklight | - | no | yes | no default OSD. Install the tpb rpm as a workaround. |
Fn-Space | zoom | thinkpad_acpi | HAL | no | Known Xorg limitation, scheduled to be fixed with the new XKB2 extension, whenever that may be. |
VolumeUp | Volume Up | - | no | yes | no default OSD. Install the tpb rpm as a workaround. |
VolumeDown | Volume Down | - | no | yes | no default OSD. Install the tpb rpm as a workaround. |
Mute | Mute | - | no | yes | no default OSD. Install the tpb rpm as a workaround. |
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. Causes a dialog asking you what to do. |
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. See below. |
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 /etc/sysconfig/irda after which the irda service can be started (# 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
