Problems with eGPU and monitor setup - Ubuntu 18.04
it detects both GPUs just fine. The problem comes from trying to get an additional monitor working besides my laptop's own screen. I used eGPU switcher ( https://github.com/hertg/egpu-switcher) as well as writing my own xorg configuration file but the best I got was that the second monitor (connected to 1080ti on eGPU) worked, but that my laptop monitor no longer got detected or worked. Any suggestions or tips?
I fixed a similar issue on my system today with a one line change in a config file. This is copied from my askubuntu response here:
Run X11 as root. The one line fix is to add this to this to /etc/X11/Xwrapper.config:
needs_root_rights = yes
All my external displays are now detected and working on gdm3
