I am usually using Ubuntu 20.04 with Gnome DE. Since my laptop is slow, I wanted so see how it will work with XFCE. In the login screen, I switched to XFCE and it was a terrible experience with very slow responses. Now, I can not get back to Gnome, I get no option to chose DE, it is booting into XFCE directly and the screen is stuck. How do I change it back to Gnome using recovery mode? I am using HP laptop.

  • At the DM (display manager that performs greeter functions) you select which desktop you'll login in with when you select/enter your username & password. When you installed xubuntu-desktop (you weren't specific as to how you installed it so I've made assumption) you were asked which DM you want to be used (Xubuntu/Xfce defaults to a different DM to GNOME thus the question), and it's how you answered this question that dictates how you're asked to select desktop. If you have autologin enabled, you need to logout to get asked. – guiverc Feb 11 '22 at 09:29
  • I did not install any thing, just choose XFCE from the DM menu. Now it goes directly into XFCE. I do not have the choice, It does not give this option to select DE. Therefore, I asked about recovery mode. Nothing works in GUI. – hans Feb 11 '22 at 11:35
  • You said you "switched to XFCE" which I don't know what what you meant.. This install I'm using is a Ubuntu install initially; on which I added xubuntu-desktop (ie. XFCE), lubuntu-desktop (was LXDE but now is LXQt), ubuntu-mate-desktop..... ie. I added them so I could switch from one desktop to another just by logout & logging back in switching desktops (at the DM; which is sddm for me; having gdm3 for Ubuntu/GNOME, and lightdm for ...).. What do you mean by "switched to XFCE" (if you re-installed; your GNOME is likely gone) – guiverc Feb 11 '22 at 11:41
  • "switched to XFCE" means choosing XFCE in the login screen. – hans Feb 13 '22 at 09:15

I removed xubutnu and xfce installation using the root terminal in the recovery mode. :See link here

  • You've answered your own question; though I don't see how this does.. either way removing the xubuntu-desktop will still leave parts behind (eg. the plymouth logo, which will say Xubuntu until you change that back to whichever you want to use). – guiverc Feb 11 '22 at 11:57
  • After I purged xubuntu and XFCE, I got the login screen back and the XFCE option was not available anymore. That all I needed. – hans Feb 13 '22 at 09:14
