As title says. Obviously I could setup different virtual machines or spend the time and install all the DEs in one VM if it is even possible without breaking the OS. I'm wondering if there is an already made iso or something that installs all the maintained DEs for trying.
In that case, wouldn't it be possible to try this on any distro? Just make a new user per DE? Also, I think what they're pointing out is that you can change DE and rollback to where you were before
