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
Install the DEs manually instead of from metapackages so ,out don’t end up with their entire software suites being installed. Additionally, probably use Debian instead of Ubuntu if you’re gonna be doing stuff like that, less fingers in the pie make for an easier tinkering experience.
In my experience the main issue are configuration conflicts not package issues. They’re usually just annoying issues not breaking issues.
