I've experienced similar problems lately on a system where I had erroneously left settings to cater for startx, but these were in addition to what the Display Manager was doing (sddm). As a result there were two sessions starting as shown by ck-list-sessions and this created a clash blocking things like BT, USB mounts from userspace (on any DE) and the like. You may want to check if you have left any manually created session files in / etc/X11/Sessions/ and ~/.xinit or ~/.xsession. -- Regards, Mick
