Question

I installed Artix OpenRC with lightdm. When lightdm opened I pressed

ctrl + alt + F1 to go to the tty
Then I went back to lightdm to login

A wired thing happened that is it prompt me to login twice and this number showed up instead of my host name

I removed lightdm and changed my hostname in /etc/hostname and still gives me this number instead

One other thing is when it boots up it gives me a failure in starting nvidia-uvm

What could cause this problem? And how to fix it?
