Public bug reported:
The brightness keys on my Asus x5dij show the following behauviour:
Instead of of changing brightness over the whole available scale, they just
toggle between the first two values possible.
The values in /sys/devices/virtual/backlight/acpi_video0 are:
brightness: 0 or 1, respectively
actual_brightness: 0
max_brightness: 13
However, it's possible to change the brightness by hand by writing to
/sys/devices/virtual/backlight/acpi_video0/brightness or the /equivalent
/proc-file.
A workaround is unloading/reloading the "video" kernel module, but after
this the brightness-changing-OSD doesn't appear anymore and I guess
there may be other issues, at least it's not the elegant way ;)
Don't know what package to file against. Please tell me what further
information to provide. I'm using Jaunty.
