I have tried to experiment with different desktop environments. I completely removed Ubuntu-desktop-environment and installed Kubuntu-desktop. Then after some days I installed Lubuntu-dektop.

Now, I want to get back to my Ubuntu-desktop. How to do it?


Update: I have done the following:

sudo apt install ubuntu-desktop

sudo apt-get install ubuntu-gnome-desktop

sudo apt-get install gnome-shell

And as a result I have got many options to login with. But When I choose Ubuntu after reconfiguring into lightdm it says insufficient memory.

    First, for the purposes of experimentation, I would suggest playing with a VM until you find what you like. Then you don't have these problems. Secondly, what is your memory and disk space like before you log in? You could use CTRL-ALT-F1 to open a virtual terminal and get the answers with df and free and then get back with CTRL-ALT-F7. – wxl Jul 26 at 17:43
