I’m new to nix os, coming from arch linux. I’ve been trying to install it on an old nx7400 laptop, but so far I haven’t managed to start any graphical environment. First I tried the minimal install, but it failed to launch the display manager with some very undescriptive errors, so I tried doing it from a graphical installer instead. It installed without issues, but after launch it just prints:
Starting Display Manager...
[ OK ] Started Display Manager.
Starting Display Manager...
[ OK ] Started Display Manager.
and nothing is being shown. I’ve no idea why this happens. Could anybody help me with it?
I have disabled auto login, and I’m being greeted with a blinking cursor on a black background. The display manager throws a different error now (in the systemd journal):
# Edit this configuration file to define what should be installed on
# your system. Help is available in the configuration.nix(5) man page
