I noticed a weird behavior when the screens goes locked, the brightness level is automatically increased when the screen turns on back again. I also noticed that the file /sys/class/backlight/amdgpu_bl0/actual_brightness is automatically changed to a higher level that the one that I had before the screen went locked. The problem WAS NOT PRESENT in kernel version 15.5.0-25-generic. After that version the problem comes as described. Thank you.
