Public bug reported:

Binary package hint: xorg

hello,
i have two computer, both on karmic (and both with Intel graphic card)
unfortunately there is no way for me to configure the brightness level, nothing is working : brightness keys, xrandr, xbacklight.

i don't know if it is really an xorg bug, xorg an Intel driver bug

of course i also tried to echo some /proc/acpi/video/OVGA/DD0*/brightness devices
but when i do so i receive a permission denied, even as root
a cat on the same element, give me
<not supported>

i read some tutorials speaking about a file in /sys/class/backlight
but on both computer this directory is empty


running xbacklight gave me this output 

No outputs have backlight property
