Wow! I found a working WORKAROUND for everybody that reset the brightness to 0 after every reboot! Its really easy, without scripts, etc. Its not perfect, but for now its good enough for me. It works with xfce, but i’m sure that its works also with kde as you know where the options are.
This is what you need do to (in xfce):
- Go to the settings of xfce power manager
- Go to tab display
- Set the inactivity in accu on 10 sec and 10% brighness. Same with power.
- Set the main brightness a littlebit higher, try to set to 11% NOT lower or same as 10% or else it won’t work!
- Reboot and after reboot you need to wait 10 seconds extra. Bam you are inactive and the screen go to 10%,
- Touch the laptop and BAM 11% brightness!
It works nice for me and i can wait for the real fix from the devs.
