I use KDE for my actual computer, and I like using LXQT for my VMs.

Sometimes, under heavy load or after prolonged use KDE starts getting a little buggy, so I run a simple command to reset it.

kquitapp6 plasmashell && kstart plasmashell

Edit : I also put xfce on a craptop that has LMDE on it.

EDIT 2: I doubleposted by accident.
