I tried LXDE and I really don't like it so I would like to get rid of it. I installed it by typing:
sudo apt-get install lxde
and tried to remove it by typing
sudo apt-get purge lxde && sudo apt-get autoremove
But the LXDE option is still in LightDM's desktop menu. Can anybody tell me how to remove it from LightDM's menu?
