Debian Lenny on a Thinkpad T400s

(This page is kind of updated to cover Debian Squeeze)

Emacs keys in applications

E.g. google-chrome:

Edit/create .gtkrc-2.0, so it contains:

gtk-key-theme-name = "Emacs"

Kernel

You need a kernel with bigmem support to see more than 3GB ram.

Use backports and install something like 2.6.32-bpo.3-686-bigmem

Touchpad

To see status:

xinput list-props "SynPS/2 Synaptics TouchPad"

http://www.thinkwiki.org/wiki/Synaptics_TouchPad_driver_for_X

Wireless

apt-get install rmware-iwlwifi wireless-tools

Also see: http://wiki.debian.org/iwlagn

If you have weird problems like:

# ifconfig wlan0 up                                                                                                                                 
SIOCSIFFLAGS: Unknown error 132

Check the little button on the right side of the laptop -- it should show some green and be in the rightmost position.

Suspend

apt-get install uswsusp

The following script works:

test -f /usr/share/acpi-support/power-funcs || exit 0
test -f /usr/sbin/s2ram || exit 0
rmmod usb_storage
rmmod uhci_hcd
rmmod ehci_hcd
/usr/sbin/s2ram -f -a 1 -m
modprobe uhci_hcd
modprobe ehci_hcd
modprobe usb_storage

But how do i call it on closed lid? The acpi-stuff does not seem to catch it.

Ok, in a way it does, the state is found in =/proc/acpi/button/lid/LID/state= and that works:

state:      open
state:      closed

We can use that for a quick hack:

Append the following line to the script:

grep close /proc/acpi/button/lid/LID/state || exit 0

And put the script in roots crontab:

* * * * *       /root/shell/sleep-on-lid-closed.sh >> /tmp/sleep-on-lid-closed.out 2>&1

If the lid is closed, the machine will suspend within the next minute. That is good enough for now.
