Reverting to nouveau looked like it went ok, removed the checkmark from nvidia and clicked "save".
However when it was done, I had no more auto-login, and I was in an endless loop trying to log in with lightdm. Booted into recovery mode and played a bit. The following was present in modprobe.d:
Code: Select all
nvidia-blacklists-nouveau.conf --> /etc/alternatives/glx--nvidia-blacklists-nouveau.conf
nvidia.conf --> /etc/alternatives/nvidia--nvidia-modprobe.conf
I borked it completely by removing nvidia* from modprobe.d, and now booting into the mindless lines and colors of incorrect/no refresh rate setting, recovery mode or no.
Be back after I spank this unruly beast... Or it spanks me...
Edit: Well, it spanked me. Couldn't get nouveau going again, had to manually reinstall nvidia, and finally had to purge plymouth to bring it out of zombie mode. I'll mess with it some more later...
