    services.xserver.videoDrivers = [ "qxl" ];
    services.spice-vdagentd.enable = true;

I just tried that and it resulted in a black screen. I suppose there is more to using that video driver than just that line in a nix configuration?

Hey! I was misinformed, try removing:

   services.xserver.videoDrivers = [ "qxl" ];

Then you're only left with the spice line. I think qxl requires other configuration.
