@Bro666 well yeah, it is possible to install multiple DEs and it should work just fine. though i wouldn't really recommend it since the configs will break a lot from the DEs fighting, and you'll have a lot of redundancy because of the same utilities and apps for different desktops coexisting.. not saying it is not possible though, but do it at your own risk

@ikidd @kde no. you cannot install multiple DEs without breaking stuff. especially different versions of the same DE. if it is even possible, i would not recommend it.
