There is a problem with the backlight of my FTS Celsius H265 notebook and its
NVIDIA G96GLM [Quadro FX 770M] graphics card. When I leave my computer
unattended for a while Xfce turns off the backlight of my computer as there is
no input. However as soon as it does so my screen stays permanently black. When
I move the mouse the backlight goes on again; however the screen content
remains black. The same problem occurs with s2ram; after awaking from s2ram
Num-Lock works well but the screen stays black. However to evoke this error it
isn`t necessary to s2ram; the desktop environment just needs to switch the
backlight off. - using kernel 4.15.0-rc9+.
