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

Hi Joël,
until I rebooted today, KDE did use intel_backlight for me. In the
meantime there was an update, but it seems they only fixed some font
size issues.

Unfortunately, it seems they will prefer the type=firmware backlight
controls over type=raw, as it's probably the safest choice. Maybe we
should just skip the whole gnome-power-manager/powerdevil/... mess and
let acpid call a script that changes intel_backlight. Working
brightness
keys at the console and lockscreen is a bonus, too.
