I have a thinkpad with Intel GM graphics ;-). I need it to work so I try
not to experiment too much on it. I've just tried the ibm-acpi driver
and it doesn't work well :-(.
So far I've noticed:
* 'cat brightness' != 'cat actual_brightness' upon bootup (doesn't have
to be true if there is hardware brightness limiting or level changing in
action but that wouldn't be the case here and this could be fixed
easily).
* 'echo 0 > brightness' lowered the intensity but by a level or two, not
set it to level 0. A couple of more attempts and it did jump from 7 -> 1
and so on, it seems erratic.
actual_brightness always seems to be correct, as does brightness so it
looks like its not updating the hardware correctly.
