Public bug reported:
I just installed Ubuntu 22.04 on my new laptop Asus Vivobook Pro 15 OLED. 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.
