Hi Michael,

Good idea, thanks! I just reconfigured the files in /etc/acpi/events/ to
use /sys/devices/pci0000:00/0000:00:02.0/backlight/acpi_video0/brightness
and it works well in the console now :-)

Now I just need to fix two things in KDE:

- Disable brightness control by KDE. In "Global Keyboard Shortcuts" => "KDE
Daemon" I have already assigned "None" as a key to the "Increase/Decrease
screen brightness" actions, but it still happens somehow.

- Disable "suspend to RAM when closing the LID". I tried many times,
changed all the power profiles but somehow it continues to happen. This
made me crazy! I had to disable STR in the kernel options altogether.

There are a lot of useful settings in KDE, but too bad many of them don't
seem to have any effect :-/

Best regards,

Joël
