When I start Xorg with the NVIDIA proprietary drivers and my eGPU connected to my laptop, it only shows a blank screen. I tried to decipher the Xorg.log file but I don’t know enough about GPU and drivers to see what could be the issue. Any help is much appreciated!
What happens if you do not have the external monitor attached? Does the laptop screen function properly?
Some devices have had an issue with external monitors & nvidia while running wayland, but the external monitor works normally when logged in with xorg. It would be worth checking that out in your situation.
I’d run dmesg | grep nvidia to see if there were errors loading the module. It may be falling back to nouveau. Also check lsmod | grep nvidia to see if the module is loaded.
I found the issue later yesterday. It was caused by my settings to scale my HiDPi screen. These settings where in my ~/.Xresources. Maybe they weren’t picked up or something was making Xorg/NVIDIA driver unhappy.
Anyway, I added xrandr --auto in my ~/.xinitrc to override all settings I use and it solved the issue.
