Switching back from Unity to KDE

Question

Currently, I have a Kubuntu 20.04.

After some item I've installed Unity, how I can switch back to KDE ?

You can have multiple desktops installed; you get to select the one you'll use for that session when you login; so logout or boot, and at the greeter (DM login) select KDE/Plasma and you'll be using that session (the default is usually last used, but you can change that) — guiverc, Nov 22 '21 at 21:28

There two ways to proceed:

If your installation of Kubuntu is not corrupted then logout or reboot and select Plasma session on login screen.
If Kubuntu installation is corrupted, then (re)install Kubuntu desktop back by
```
sudo apt-get update
sudo apt-get install --reinstall kubuntu-desktop^
```
While executing above command confirm using SDDM as login screen, then reboot and select Plasma session on login screen.

Do you have auto-login enabled? Please manually run sudo dpkg-reconfigure lightdm and select SDDM here, then reboot. – N0rbert Nov 23 '21 at 05:08
I will update after reboot. Thank you! – Michael D Nov 24 '21 at 12:04
