Lose gui for login

I’ve been using Netrunner rolling for the past 4 months and finally ran into something important I cannot solve. I replaced my video card. When I restarted to fix the expected scan and resolution issues, I had a CL request for my login and password. Neither my administrator nor user credentials worked. I took the new card out and re-installed the old one. Booted right up to my “normal” login screen. What am I missing something to get past the CL login?

You will need to change the driver for the new card with mhwd. If you we’re using a proprietary non-free driver (nvidia or catalyst) prior to installing the new card then you will need to be sure and change to using the free drivers first.

sudo mhwd -a pci free 0300
