--- Comment #31 from Paulo Nascimento (paulo.ulusu at googlemail.com) ---
Error messages are:
Mai 03 23:01:37 pn-legion systemd-backlight[861]: Failed to get backlight or
LED device 'backlight:acpi_video1': No such device
Mai 03 23:01:37 pn-legion systemd-backlight[862]: amdgpu_bl1: Failed to write
system 'brightness' attribute: No such device or address
Mai 03 23:01:37 pn-legion systemd[1]: Failed to start Load/Save Screen
Backlight Brightness of backlight:acpi_video1.

I think it has to do with the NVIDIA device.
