I’m planning on moving (back) to Linux from Windows, but I’m not sure which desktop environment I want to use. What’s the easiest way to try them all out? Just do a bunch of dnf/apt installs? Is there a distro or project out there that makes this easier?
Looking to try out kde, gnome, budgie, cinnamon, xfce, others
Why not install a live disc type image to USB and try out different varieties? Linux Mint offers three live images with Cinnamon, MATE, and XFCE.
I quickly found this article on installing them to USB: https://itsfoss.com/linux-mint-live-usb/
Many popular distributions offer live images so you can try before installation.
