Ever since switching to Cinnamon I've had hell with the DE freezing up when changing video outputs which I do quite a lot. I have GPU passthrough for virtual machines which take over a screen and a TV which is on only some of the time. So, after much cursing and yelling yesterday I reinstalled Manjaro but with KDE.
I have at this point run on this computer GNOME, Xfce, Xfce+i3, Cinnamon, and now KDE. Haven't done much distro hopping, but I sure have DE hopped. So far I've liked using GNOME the least and Xfce+i3 the most.
