  • Virtual Machine Users: Press the Right Ctrl key or Host key combined with F2.
  • Physical Machine Users: Press Ctrl + Alt + F2 or F1 to F6 might also work on some systems.

  • For GDM3 stands for GNOME Display Manager:
sudo dpkg-reconfigure gdm3
  • For Light Display Manager:
sudo dpkg-reconfigure lightdm

Now restart the display manager.

sudo service display_manager restart

Replace display_manager with gdm3 or lightdm as appropriate.

3. Addressing Corrupted Files

sudo fsck /dev/sda1

Replace /dev/sda1 with your actual partition.
