I have tried it on several distros before and it always causes problems because you get a million more packages intermingled with your already installed packages and sometimes you get conflicts or whatever. But it usually messes up my system. is there a safe way to have several desktops installed? or do you pretty much install a new one then remove the old one? thanks
How are you installing the DEs? I've consistently had at least 3 DEs on every machine I've had for the past decade and never had any issue with it. The secret is that I installed them through the package manager and don't uninstall parts of it or anything of the sort, they're there for when needed, I have enough disk space that it's a non-issue.
