Hi everyone
While resuming from suspend, system is setting screen brightness to max available level, even if it was previously set to minimal
If it matters, I had installed How to reproduce
  1. Suspend laptop using GUI
  2. Resume laptop
  3. Screen brightness is getting reset to max value
Expected behavior
  1. Screen brightness should be on same level as before suspend
I tested this with:
  • Current updated plasma install
  • Calculate Linux 17 plasma liveCD session
  • Calculate Linux 17 xfce liveCD session
Laptop spec's
  • HP ProBook 4530s
  • i3 2310m
  • Intel GPU
  • 4GB+4GB RAM
  • Battery is not plugged in

I accidentally discovered same bug, while I was testing another distro (LiveCD) with 4.9.20 kernel.

On my Calculate-linux installation, I'm currently using binary with 4.9.17-calculate kernel.
