Lenovo IdeaCentre K330

The specific system I took for reference has the following hardware configuration:

Intel Core i7 2600
NVIDIA GeForce GT 545 Latest supported (proprietary) driver (390.xx)
Some SSD (originally had a Seagate Barracuda hard drive)

This hardware configuration was motivated by #1297

I recommend enabling xserver instead of trying to use Wayland. As documented in the above linked issue, using Wayland with this rather old hardware lead to the system freezing after a short time of operation.

{
    services.xserver.enable = true;
}
