In my case, the problem was caused by a file named "gnome-wm.desktop" at "~/.local/share/applications/" and was solved after deleting it. The content of this file was: "[Desktop Entry] Exec=gnome-wm Hidden=true Name=Window Manager NoDisplay=true Type=Application X-GNOME-Autostart-Notify=true X-GNOME-Bugzilla-Bugzilla=GNOME X-GNOME-Bugzilla-Component=general X-GNOME-Bugzilla-Product=gnome-session X-GNOME-Bugzilla-Version=2.32.0 X-GNOME-Provides=windowmanager X-Ubuntu-Gettext-Domain=gnome-session-2.0"
