Hello,
I'm testing 2.6.23.1 kernel with the latest thinkpad-acpi on my X60s.
During boot I can see this line:
thinkpad_acpi: standard ACPI backlight interface available, not loading native
one...
and brightness control partially works at-least in console mode (without X11)
with video ACPI module loaded. Without video module I'm not able to change
brightness.
In X.org with video ACPI module loaded screen blinks when I press Fn+Home/End
but brightness level never change from 100%. Then when I switch to console
everything is OK and proper brightness level is set (but from this moment and
from moment when I overstep min/max level by pressing Fn+Home/End reacts
brightness control very slow). - Maybe problem with i915 driver ? Exists
workaround ?
In previous kernel (2.6.22.9) without ACPI video module I can smoothly change
brightness level, but everytime when I switch to console/X it shoots up to 100%
and there is also problem with slow reaction time after overshooting it.
I can do some testing on my nb.
