** Description changed:
1) Kubuntu maverick beta
2) 2.6.35.19.20 0
3) Pressing the brightness keys should increase/decrease the brightness by 1
step
4) Pressing brightness-down decreases brightness by two steps, pressing
brightness-up increases the brightness for a split-second, then decreases it
back to what it was. It's impossible to increase brightness using the keys, I
have to increase by other means (powerdevil slider, xrandr --set, etc..)
Hardware: Notebook Fujitsu-Siemens Esprimo mobile U9200 (intel GM965)
Annotated showkey - s output:
# single brightness-down
0xe0 0x4c 0xe0 0xcc
#single brighness-up
0xe0 0x54 0xe0 0xd4 0xe0 0x4c 0xe0 0xcc
Tried "acpi-backlight=vendor" option to no avail. Worked fine way back
before intel KMS (Kubuntu 8.04). Xrandr show two backlight properties,
in case that's relevant:
$ xrandr --prop
