Hi!!

I'd like to know how kde manage the brightness. Which daemon manage it?

I have some problems with it.however, I'm getting crazy to configure the brightness!! I have three different devices :

Code: Select all

/sys/class/backlight$ ls -l
lrwxrwxrwx 1 root root 0 Jun  8 22:22 acpi_video0 -> ../../devices/pci0000:00/0000:00:01.0/0000:01:00.0/backlight/acpi_video0
lrwxrwxrwx 1 root root 0 Jun  8 22:22 acpi_video1 -> ../../devices/pci0000:00/0000:00:02.0/backlight/acpi_video1
lrwxrwxrwx 1 root root 0 Jun  8 22:22 intel_backlight -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight


I'm using KDE, if I change the brightness with the hot key , the system gets crazy, I can't use it any more! I have to wait some minutes before the general behaviour becomes normal again ( in this case video0 and video1 change but not intel )

If I change them with echo command I don't have any problems Although only the brightness value associated with that device changes whilst the other one remain the same.
If I use Kde power setting change only device0 brightness, with some problems as well ( if I put the minimum it doesn't change )

Can I set which device KDE should use ?

Please don't post in multiple forums. I'll answer your question in the other forum shortly.
