Installing Fedora 11 on a ThinkPad T60

NOTE!

This is based on the x86-64 pre-release version of Fedora 11, but should give a good indication of what to expect of the final release

NOTE!

ThinkPad T60p is reported here as well

Tested and Verified on Fedora 11

Information in this section has been tested and verified using Fedora 11, including the pre-release (post-beta) version. The development version of Fedora 11 (rawhide) is quite stable and even suitable for day-to-day use, if you are a bit brave. You will be automatically switched over to the release version of Fedora 11 if you keep everything up to date.

Installation

Installation is straight forward; you can follow the generic Fedora install instructions.

Configuration

X Server (Intel)

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.

Fedora 11 uses KMS (Kernel Mode Setting) by default, which for now has some up and down sides for external displays. The down sides are that external displays attached during boot might not function properly (mostly they may have non-optimal resolution), but they do when hot plugged afterwards. Another down side is that currently mirror mode is very limited as the ThinkPad LCD (LVDS) is limited to one single display mode, so only if the external display supports this same mode can you activate mirror mode. On the other hand with KMS enabled the maximum virtual display size is now 4096x4096 (2048x2048 without KMS) meaning you can have an extended desktop.

These issues have been reported to Red Hat bugzilla.

On a T60p, displays work well, with multiple mirrored and non-mirrored displays and even with one of the displays being rotated! This may also work on a base T60, as there has been a lot of effort put into getting this to work right.

One thing that still doesn't work quite right is screensavers and screen blanking. There is something wrong with the timers, which may result in your screen blanking while you are typing. Recovery is a simple as waiting until the screen is completely blank and then type or click to wake up the screen.

Another thing that doesn't work quite right is screen resolution when booting with multiple screens. If one screen doesn't not have a preferred resolution, a poor resolution may be used for both screens during the booting process. Everything works fine after login, however.

Desktop Effects

Compiz (wobbly windows, desktops on a cube) seems to work. Direct display of video may be problematic with Compiz, however.

dpi

On the 1400x1050 (and 1600x1200) LCD Fedora comes up with a DPI of 124 (or higher). While this is correct for the physical screen size, it waists a lot of screen real estate.

To change to the more typical 96 DPI, go to System -> Preferences -> Appearance. Now in Appearance Preferences select the Fonts tab and press the "Details ..." button. Here you can change the dots per inch to 96. Of course, many things will shrink, but that is what you wanted, after all.

Wireless Network

Both the Intel and Atheros wireless should work out of the box.

Atheros was tested and works, but you may encounter occasional disconnects and reconnects. Intel wireless also works.

ThinkPad keys

ThinkPad keys are handled by a mixture of the thinkpad_acpi, acpi button, acpi dock and acpi video drivers.

NOTE!

Due to Xorg limitations, some keys that cause HAL events work with Xorg (ThinkVantage and Fn-F7) and others do not. This is a known limitation that should be fixed with the next major Xorg (v1.7) release.

Ultrabay

The Ultrabay has some glitches out of the box with respect to hotswapping. It is possible to lock the machine when pulling out devices, even the CD/DVD device.

The culprit is that the Ultrabay pre-eject switch is not hooked into anything useful. It does cause udev events, but nothing is listening for them. When a device that has a mounted partition or CD is actually pulled out it is too late to do the right thing. Fedora 11 will usually just complain, sometimes bitterly, but may also lock up for some unknown reason, even if just pulling out a CD/DVD device with a mounted CD.

Manually unmounting before removal will help. Manual powering down may also be required for correct performance.

A better solution is to set up a udev rule and script to handle the pre-eject switch event for Ultrabay devices that have mountable things in them as in [How to hotswap Ultrabay devices].

The revised solution here works well. Pushing the pre-eject switch either does the unmounting and powering off and then emits a low beep, or fails and then emits a triple beep. After success the device can be safely removed or the eject lever can be pushed back and everything will be remounted. After failure pushing the eject lever back in does nothing, permitting continuing as if nothing happened or allowing changes to be made before the next attempt to remove.

Unfortunately the code below is complex and may be fragile. A better solution would be very useful.

To set this solution up, first create the file /etc/udev/rules.d/50-ibm-ultrabay.rules with the following content

ENV{BAY_EVENT}=="3", ACTION=="change", SUBSYSTEM=="scsi", RUN+="/usr/local/sbin/ultrabay_eject"

Make sure it is owned by root and has the following selinux security context # chcon system_u:object_r:etc_runtime_t:s0 /etc/udev/rules.d/50-ibm-ultrabay.rules

Then create the executable file /usr/local/sbin/ultrabay_eject

#!/bin/bash

ULTRABAY_SYSDIR=/sys$DEVPATH
shopt -s nullglob
logger ultrabay_eject storage device $DEVPATH

Untested on Fedora 11

The Fingerprint reader and the WWAN options have not been tested yet. If you tried them with Fedora 11, please update the table.
