I installed LXDE on my Jessie laptop for exploring it (alongside GNOME). Now, I removed LXDE from Tasksel and installed Mate desktop. I think only some packages are removed. Also, the gdm (or whatever that's called where we login and select out desktop environment) stills lists LXDE. I have tried tasksel remove LXDE and googled a lot. Still expecting solution.
