Hey all, I’m trying to set up my new build to use the GPU for the display output instead of the built-in display of the motherboard and I can’t seem to get it to work. That is to say that when I plug in a display port or HDMI cable from my GPU to a monitor, no input is detected from the monitor. When I connect the monitor to the mobo’s built-in display port or HDMI, it works fine.
I’ve followed the Nvidia setup documentation including the
Boot to Text section in the manual. However, when run
sudo nixos-rebuild boot and then
sudo reboot, it boots into a screen with a cursor in the top left. I can switch to another tty to get a login screen where I can login and edit the configuration.nix file.
What I’ve been able to do is to isolate the line in the title, this one:
services.xserver.videoDrivers = [ "nvidia" ];
to be the line that is causing the problem. When I have that line commented out, the GUI starts fine (I’m using Plasma). When I uncomment the line, I get that hanging boot.
For diagnosis, my system is this (note the 4070 TI is found as a device by the OS):
