I cannot load KDE, XFCE or any desktop environment other than GNOME in my Fedora 22 system. Every time I try startkde I get $DISPLAY is not set or cannot connect to X server. Tried all the solutions here, here and here and it still doesn't work. How to fix this?
Cannot start KDE in Fedora 22

If you type in a shell type Xand there's an error, you forgot to install xorg-server.Check this too :fgrep '(EE)' /var/log/Xorg.0.log
