Just installed a new Sparkly on my desktop, fresh download, XFCE desktop, fully updated, 64-bit. I've wanted to experiment with other desktops, so I installed a few others, such as Budgie, using APTus. Install of the desktops seemed to work fine. I logged out, set Budgie as my new desktop, started the system, and XFCE appeared instead. Indeed, no matter how many alternative desktops I install, and check off at boot time as my desktop, XFCE persists. Any idea what's going on here? Thanks.
Yes I do my friend! At the beginning we want linux and we want it all right?! than you haven't read what the installer states before starting, and your problem was surely the same home directory for all of them, and that do not work well. Try creating a new user and setup his default session, but I strongly recommend you uninstall everything else to "clean the mess"
