Installing Fedora 11 on a ThinkPad T60

NOTE! Some functions mentioned below might rely on available Fedora updates being installed. So if you're having problems with something that is supposed to work, please ensure you have all available updates installed NOTE! This is based on the x86-64 version of Fedora 11 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.

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.

For the moment external displays do not work. When you boot with an external display attached, you will get a non-optimal resolution on the external display, and the LVDS will be off. When you logon the system will hang, and you will have a black display, but with functioning mouse cursor. Attaching a display afterwards also freezes the system when you try to active extended desktop.

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.

A workaround to the single mode problem is to add the modes manually with xrandr. Below is a script I created that adds the most common modes for a 1400x1050 LCD ThinkPad

#!/bin/bash
#
# modelines created with "gtf 640 480 60"
#
xrandr --newmode "1280x1024_60.00"  108.88  1280 1360 1496 1712  1024 1025 1028 1060  -HSync +Vsync
xrandr --newmode "1024x768_60.00"  64.11  1024 1080 1184 1344  768 769 772 795  -HSync +Vsync
xrandr --newmode "800x600_60.00"  38.22  800 832 912 1024  600 601 604 622  -HSync +Vsync
xrandr --newmode "640x480_60.00"  23.86  640 656 720 800  480 481 484 497  -HSync +Vsync
xrandr --addmode LVDS1 "1280x1024_60.00"
xrandr --addmode LVDS1 "1024x768_60.00"
xrandr --addmode LVDS1 "800x600_60.00"
xrandr --addmode LVDS1 "640x480_60.00"

X Server (ATI)

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 (Dots per Inch) 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.

OSD

By default OSD (On-Screen-Display) will only function for the brightness keys, not for other functions such as Volume.

For this you can install the 'tpb' package from the standard Fedora repository

yum install tpb

But afterwards, you need to edit /etc/tpbrc and change

#OSDBRIGHTNESS OFF

to (remove the #)

OSDBRIGHTNESS OFF

Otherwise you will get two OSDs when using the brightness keys, one from gnome-power-manager and the other from tpb.

Wireless Network

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

Atheros WiFi

Atheros was tested and works, but you may encounter occasional disconnects and reconnects. In addition you might have problems after a suspend cycle. It seems the Atheros chip can get stuck sometimes, require a shutdown (not just a reboot) before the driver can initialize the chip again. Also the WiFi LED remains off.

As a test I tried the 2.6.31 fedora 12 kernel from rawhide, and it does improve matters, the chip no longer gets stuck, but I it can still take several tries before I get a network connection established. After a suspend/resume cycle, I occasionally have to unload/reload the ath5k module. Also the WiFi activity LED works.

Intel WiFi

Intel wireless was tested and works.

ThinkPad keys

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

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-thinkpad-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 right selinux security context

chown root:root /etc/udev/rules.d/50-thinkpad-ultrabay.rules
chmod 644 /etc/udev/rules.d/50-thinkpad-ultrabay.rules
chcon system_u:object_r:etc_runtime_t:s0 /etc/udev/rules.d/50-thinkpad-ultrabay.rules

Then create the executable file /usr/local/sbin/ultrabay_eject with the following content

#!/bin/bash

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

                $major_minor =~ m/^(\d+):(\d+)$/ or die;
                push(@tgt_rdevs, ($1<<8)|$2);
        }
        # Sort by reverse length of mount point, to unmount sub-directories first
        open MOUNTS,"</proc/mounts" or die "$!";

        close MOUNTS;
        foreach $m (@mounts) {
                ($dev,$dir)=@$m;
                next unless -b $dev;  $rdev=(stat($dev))[6];
                next unless grep($_==$rdev, @tgt_rdevs);

                } else {

                        system("notify-send -u normal -t 300000 \"Unmounted $dir\"");

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 11

The WWAN option has not been tested yet. If you try it with Fedora 11, please update the table.
