I installed kwin yesterday, using this command: sudo atp-get install kde-window-manager
then I thought it didnt work, so I also did this command, then rebooted sudo apt-get install kde-workspace-bin
now it did work.
However I really want to remove it because I lack disk space. How do I completely remove kwin, to ubuntu basics. So that the login screen is back to the original ubuntu login screen and I have more freed disk space.
I tried sudo atp-get remove kde-window-manager and sudo apt-get remove kde-workspace-bin
the login screen is still different from the original ubuntu login screen, and I gained a mere ~12mb disk space instead of ~110mb used for kwin.
Thanks in advance
