2021-01-12 Thread A A
When using multiple monitors, and disconnecting and reconnecting them, I noticed that Ubuntu 20.04 likes to set the external monitor's brightness to 0.06, and the laptop's brightness to maximum. This is done without changing the file at (/sys/class/backlight/intel_backlight/actual_brightness). I h
