View source for Installing Debian 4.1 on a ThinkPad T61p

A short guide to get you working with X, Wireless intel 4965, and sound.

I installed the Debian Etch 4.1 release and thereafter edited the /etc/apt/sources.list. Replaced etch with testing and there after apt-get update and apt-get dist-upgrade.

Install the linux-image-2.6.22-5-i686 and the linux-headers-image-2.6.22-5-i686 then reboot to reflect the changes and load the new kernel.


X:
----
Download NVIDIA-Linux-x86-169.07-pkg1.run from Nvidia
sh NVIDIA-Linux-x86-169.07-pkg1.run and follow the instructions

Wireless:
----
iwlwifi-4965-ucode-4.44-17.tgz<br>
mac80211-8.0.2.tgz<br>
iwlwifi-1.0.0-1.tgz<br>

{{NOTE|With mac80211-10 the kernel seems to halt. I could not get it to work but using the above files everything runs smooth.}}


unpack the above files eg. tar xzvf <filename>
From iwllwifi-4965-ucode-4.44.17
cp iwlwifi-4965.ucode /lib/firmware

From mac80211-8.0.2
make patch_kernel


From iwlwifi-1.0.0.1
make
make install
./load debug=0
iwconfig (Wlan0 should now be available to you)


Sound
----
There is a bug in the kernel which silences the output from your speakers. To fix this, run the following userspace program as root. Do a google on "t61_audio_hack.py"
thanks to Andrew Clunis

Save the following to a file eg t61p_sound.py and run it as root
$ sh t61p_sound.py

<nowiki>
#!/usr/bin/env python
KIOCSOUND = 0x4B2F

import fcntl, sys

import time

# Do a constant beep.
# Reset the beep every five seconds, in case it is cleared by another program.
while(True):
    fd = open("/dev/console")
    fcntl.ioctl(fd, KIOCSOUND, 500)
    fd.close()
