Bug Description
Non-Optimus laptop ASUS G752VS (Nvidia GTX1070)
Ubuntu 17.04
Xorg-Server-1.19.3
Nvidia driver 375.39
Situation on 2017-04-05:
Ubuntu 17.04 doesn't save my brightness settings. I can adjust the screen brightness, but after restarting the screen brightness of my laptop resets to maximum.
Situation on 2017-04-08:
Today I received many Ubuntu updates (kernel included), and I also installed freshly released Nvidia 381.09 driver (via “Graphics Drivers” team - Proprietary GPU Drivers PPA).
Now brightness settings are correctly saved, but I have a new problem: changing brightness level doesn't produce any effect (both with or without Nvidia driver installed)
Inside "/sys/class/
~$ systemctl status systemd-
● systemd-
Loaded: loaded (/lib/systemd/
Active: active (exited) since Sat 2017-04-08 13:37:31 CEST; 16min ago

Main PID: 684 (code=exited, status=0/SUCCESS)
Situation on 2017-04-10:
I purged Nvidia 381.09 driver and reinstalled default Nvidia 375.39 via additional drivers.
Now the situation has returned to initial problem: I can again adjust the screen brightness, but after restarting the screen brightness of my laptop again resets to maximum.
