$ lspci -v | grep -A 10 VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620
(rev 02) (prog-if 00 [VGA controller])
Subsystem: CLEVO/KAPOK Computer HD Graphics 620
[...]
Kernel driver in use: i915
Kernel modules: i915
It seems to be the open source driver 'i915' in the package:
'xserver-xorg-video-intel'.

Does not apply. No proprietary graphics drivers installed.

Interesting idea. I will install 'openssh-server' and try this the next
time.

I'm not sure. Maybe I can try the keyboard backlight function?
Or the Fn+Special-Function-Keys like: Volume or Display-Brightness ?
Thank you very much for your time.
Regards,
Jacob
