Installing Fedora 14 on a ThinkPad T41
|
NOTE!
This is based on Fedora 14 with the default GNOME desktop. Your experience with KDE may be different.
Help needed
Not all models of this ThinkPad are equal, you may have a different WiFi adapter, or some options I did not have. If you tested them, please add their status down below.
NOTE!
The original author of this page has updated his ThinkPad to Fedora 15, as such this page is no longer updated.

New in this release
Fixed or new in this Fedora release, with regards to this model ThinkPad is the following;
- External ONLY display now works when using Fn-F7 (Previously caused both displays to switch off)
- tpb is no longer part of Fedora, so no OSD any more for volume and brightness keys

| Ports | Ethernet | yes | |
| Modem | no | Requires closed-source driver. Install the slmodem rpm from the rpmfusion-nonfree repository, edit /etc/sysconfig/slmodem and set INTERFACE=alsa and ALSA_DEVICE=modem:1 and optionally the country. Then run "chkconfig slmodem on; service slmodem start" and point your dialer to /dev/ttySL0 | |

| Harddisk Active Protection | no | Fedora ships the hdapsd rpm, but not the tp_smapi kernel module, which is required to read the motion sensor bugzilla | |
| Ultrabay device removal | partial | Eject switch causes udev event, but no default udev script to handle the event to unmount filesystems in time. ata_piix does handle the removal and insertion of ATA devices. | |
| TPM (security subsystem) | yes | Enable security chip in BIOS, then "yum install tpm-tools", then "modprobe tpm_atmel; service tcsd start; tpm_version" works. | |

Tested and Verified on Fedora 14
Information in this section has been tested and verified using this Fedora release.
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.
You will also want to add radeon.agpmode=1 to work around a suspend/resume bug by forcing AGP 1X mode. Do note that forcing AGP 1x mode will mean less performance in games that copy large sets of textures around (e.g. Quake, World of Padman).
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 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 Bugzilla
- 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.
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 |
| FnF3 | lock screen | thinkpad_acpi | HAL | yes | |
| FnF4 | suspend | acpi button | HAL | partial | button works, but suspend fails on resume |
| FnF5 | wireless | thinkpad_acpi | HAL | partial | Works as a radio kill switch, kills WiFi but not Bluetooth |
| FnF7 | videomode | thinkpad_acpi | HAL | yes | |
| FnF12 | hibernate | acpi button | HAL | yes | |
| FnHome | brightness up | - | no | yes | no OSD |
| FnEnd | brightness down | - | no | yes | no OSD |
| FnPgUp | thinklight | - | no | yes | no OSD |
| FnSpace | zoom | thinkpad_acpi | HAL | no | Known Xorg limitation, scheduled to be fixed with the new XKB2 extension, whenever that may be. |
| VolumeUp | Volume Up | thinkpad_acpi | no | yes | no OSD. Hardware and Software volume controls are independent from each other. |
| VolumeDown | Volume Down | thinkpad_acpi | no | yes | no OSD. Hardware and Software volume controls are independent from each other. |
| Mute | Mute | thinkpad_acpi | no | yes | no OSD. Hardware and Software mute controls are independent from each other. |
| 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 (# systemctl start irda.service).
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 14
The following features where not tested with this Fedora release. If you have tested them, please update the table
- Intel WiFi
- Parallel port
- Dock eject
