It happens to me from time to time on Ubuntu 20.04. The screen freeze and nothing seems to work. keyboard combinations like Alt-F2 , Ctrl+Alt+F4 are not responding. logging via ssh from another machine works fine and using htop I do not see any process that is high in RAM and/or CPU usage.
What should I do to restart the display manager (gnome) without rebooting?
sudo systemctl restart gdm.service
