Installing Debian/Sarge (alternative) on a ThinkPad T42
From ThinkWiki
Some notes I took for my install (drop me a line at koalillo-at-fastmail-dot-fm):
IBM ThinkPad T42 (2373VUW)
I installed Debian Sarge (testing with selected packages from unstable/experimental).
Contents |
Kernel
- Set preemptive kernel
- Add madwifi
- Add patch from: http://bugme.osdl.org/show_bug.cgi?id=3022 , adding the 2373VUW model
- Add swsusp
-
$ make-kpkg --append-to-version -t42 --initrd kernel_image modules_image
Additional packages
- acpid
- alsa-base, alsa-utils, alsa-oss
- anacron
- gnome-volume-manager
- libc6-i686
- tpb for OSD display of IBM keys and remapping the Access IBM key
Frequency scaling
- Load modules: cpufreq_ondemand, speedstep-centrino
- Add the following to your startup sequence
# echo >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor ondemand
HDAPS
- Add module hdaps
- Add package hdaps-utils
Additional modules
- ibm_acpi
- nvram
ACPID
- To map Fn-F4 (suspend) and Fn-F12 (hibernate)
/etc/acpi/events/ibm
event=ibm/hotkey action=/etc/acpi/ibm.sh %e
/etc/acpi/ibm.sh
#!/bin/sh
case $4 in
00001004) /usr/local/sbin/suspend.sh mem ;;
0000100c) /usr/local/sbin/suspend.sh disk ;;
esac
/usr/local/sbin/suspend.sh
#!/bin/sh ifdown ath0 echo -n $1 >/sys/power/state ifup ath0 /etc/init.d/hotplug restart # testing if this solves my Bluetooth problems, see below
- Add
# echo enable >/proc/acpi/ibm/hotkeyto enable hotkey reporting to ACPI
GRUB
- Add resume=<swap device> so that the system finds the hibernated ram on power up
- Add a noresume option to boot without recovering the hibernation
Caveats
- Using cifs causes hiccups suspending/hibernating, use smbnetfs
- I get some USB errors when enabling/disabling Bluetooth after sleep/hibernation, like:
usb 4-1: device not accepting address 5, error -71googling around it seems like restarting hotplug (or reloading the usb modules) solves the problem... I'll test that.
