After I installed the Nvidia drivers my screen resolution dropped and I can't log in. When I try logging in my screen thinks for a bit, turns black with the message /drv/sda2: clean, X/Q files, Y/Z blocks (x, y, q, z are big numbers) and then just returns to the login screen. How do I fix this? I made sure to install the correct drivers, I've tried this three separate times but I keep getting this issue. I have a GTX 690, and I couldn't find any questions with a similar issue.


Try ctrl+alt+f1 before logging in graphically. It will bring up a terminal. In that terminal after you type your login name and password type startx and it should display any errors causing you not to be able to log in. If you are able to log in I would definitely consider opening up synaptic and reinstalling your Nvidia driver. sudo dpkg --configure -a (configure pending packages) at the terminal before login might help in this case as well.

  • restart your computer
  • enter into recovery mode
  • terminal will open, enter your credentials
  • just run:

          sudo apt-get remove --purge nvidia*
          sudo apt-get install ubuntu-desktop
          sudo apt-get autoremove
          sudo rm /etc/X11/xorg.conf
          echo "nouveau" | sudo tee -a /etc/modules
          sudo reboot
  • add this command to step 4: "mount -o rw,remount / " before the apt-get remove command – CMPE Sep 23 '18 at 18:16
