Package: xserver-xorg-video-intel
Version: 2:2.1.1-4
Severity: normal

The brightness control keys on my Thinkpad R60 stopped working in X
some time ago. I have probably upgraded both kernel and X.org since
then, and don't know exactly when it broke.

Pressing the keys in an X session now only causes a short flicker, but
does not affect the brightness. However the KDE on-screen display
seems to think everything is fine since I can control the level it
reports.

The brightness keys still work in a virtual console, just not in X.

"xbacklight -set" changes the brightness in a totally random way. For
example p=98 is barely visible, and most other settings give a
constant medium-bright level.

I can control the brightness at least reasonably well with
  echo 50 > /sys/devices/virtual/backlight/acpi_video1/brightness
except that levels below 30 don't seem to have any effect.

Also I can do
  echo up > /proc/acpi/ibm/brightness
or
  echo down > /proc/acpi/ibm/brightness

I have an unpatched kernel 2.6.23 (Linus' git tree) with thinkpad-acpi
0.16, hal 0.5.9.1-6, acpid 1.0.4-7.1.

The problem matches this description [1] which points to a fix in Ubuntu.

Ok closing. Not clear which package fixed this, so I am giving any
version number.
