I was able to uninstall the driver by first stopping lightdm with "sudo systemctl stop lightdm". After reverting back to Nouveau I was able to log in, but Unity didn't start. (no window borders or launcher, etc.) I fixed this by doing the following:
sudo dconf reset -f /org/compiz/ sudo setsid unity This immediately caused Unity to pop back into place! But I did a reboot just to be sure and everything is working great again now. :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589006 Title: Failed unmounting Mount unit for nvidia support in snappy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1589006/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
