Ubuntu does not boot properly

I’ve come across this issue, many a times in my personal Desktop Linux chores.

And trust me this is a very simple and pretty straight forward workaround, upon which this issue can be resolved. The above screenshot is from one of friend who randomly asked me one day and send this to me on my inbox.

1. Go into recovery mode
2. Open root shell prompt, this by default opens root shell, that is a bash shell
3. type sudo apt purge gdm gdm3
4. resume to normal boot
5. login
6. type sudo apt install gdm3 ubuntu-desktop and systemctl restart gdm
7. done
