Mirror to XR refuses to work
Hi there,
I'm trying to experiment with xrdesktop on Ubuntu 20.04 LTS and followed the installation instructions documented here. Unfortunately, whenever I execute gnome-shell-set-vr enable
I can see the below error in the logs.
FWIW: I'm using a Dell XPS 7390 with a AMD Radeon RX 580 attached as eGPU. Maybe xrdesktop fails, because it wants to use the internal GPU instead of the external one?
$ journalctl /usr/bin/gnome-shell -f
...

I also installed SteamVR within Steam using the latest stable version of SteamVR
- Room Setup within SteamVR works
- playing SteamVR Home is possible
