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.
The better approach is to grab the most popular distros that have different DE. See how the made their DE and what is possible. Also, think about what your goals are with a DE because if you are researching it then that means you have a desire in mind or want to know what a DE could do for you.
