Title:
LCD backlight brighness reset to maximum after boot / resume / login
Status in gnome-settings-daemon package in Ubuntu:
Confirmed
Bug description:
The laptop LCD backlight brightness level is not preserved. The screen
brightness always gets reset to 2-steps below the maximum level after
login or resume from suspend. This is particularly annoying when
working on battery, because after each resume, I have to make screen
darker in order to preserve energy.
It is possible to control brightness by keyboard buttons and by
status-bar slider, so brightness control mostly works. The status-bar
slider behaves a bit erratically when moved, but not sure if it is
related.
The problem seems to be not related to kernel version.
The problem existed in 18.04 as well as 18.10.
Hardware: Dell Precision 5520.
Graphics driver: Intel, using integrated GPU.
Nvidia card turned off on boot, no proprietary Nvidia drivers loaded.
