I have Ubuntu 20.04. I wanted to try different desktop environments so I installed Mate Desktop and Budgie Desktop through taskel following this link. I then decided to go back to the Gnome Desktop so I uninstalled Mate and Budgie with a list of commands, for example:
sudo dpkg --list | grep ubuntu-mate sudo apt-get remove ubuntu-mate* sudo apt-get purge ubuntu-mate* sudo dpkg --list | grep libmate sudo apt-get remove libmate* sudo apt-get purge libmate* Now I am experiencing several problems on booting. I recorded a video of the boot sequence where:
- it shows a gray screen "mate-like"
- it shows the ubuntu version in the left top area of the screen
- it shows a very quick list of commands that suddently disappear
- the login icon is different from the classic icon i saw before
- sometimes the login doesn't show and it stuck with the purple screen until a hard reset or pressing ctrl+alt-canc combination. I noticed that it happens only with power supply plugged in
Maybe is something about the grub configuration but I don't know how to solve it. Any idea?
Thanks

This gray screen seems to be GRUB2 theme for Ubuntu MATE. Remove it with
sudo apt-get autopurge grub2-themes-ubuntu-mate then reinstall whole Ubuntu desktop task by
sudo apt-get update sudo apt-get install --reinstall ubuntu-desktop^ and reboot to check the changes.
