Having the same problem in Dell 640m, (Kubuntu 7.10). The keys worked
fine in Feisty. And sometimes, in Gutsy, after restoring from hibernate
mode, the keys work again.
1. Exact HW
2. Does these two command (if run from Konsole) change brightness properly on your laptop?
3. Does your laptop return same keycodes from brightness up (212) and down (101) as documented on
https://wiki.ubuntu.com/KubuntuLaptopKeycodes page? If not, what does it report and what does "lshal -m" report when key is pressed?
Start monitoring devicelist:
14:16:51.564: platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = brightness-up
14:16:52.460: platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = brightness-down
BUT I have found that the /usr/share/acpi-support/key-constants, says another thing:
this file is imported (?) when the scritps video_brightnessup.sh and video_brightnessdown.sh are run. I manually changed the values of those constants to 212 (up) and 101 (down), but it did not work.
