Hey folks,
I am using a
- TUXEDO Pulse 14 (AMD Ryzen 7 4800H, Radeon RX Vega, integrated graphics)
- with Qubes-R4.0.4-x86_64
and already found some solutions for several problems.
There are still two things on my list which are maybe connected.
It is not possible to reduce the brightness of the build in monitor. I found a topic for that (not resolved so far):
https://forum.qubes-os.org/t/gpu-driver-necessary-for-functional-backlight-control/3544/
The issue for this topic: After connecting several different external monitor with several suitable cables via HDMI the monitor is not detected.
Using other distros this setup works => hardware is OK.

Also tried to use the xfce system tool “Display” (configure new displays when connected) without success.
Do you have an idea how to get the external monitor working via HDMI?
If you need more information / logs, please let me know.
Thanks in advance!
