This is caused by Wayland not allowing processes run as a different user to display on the desktop. Therefore using "su" or "sudo" to display a graphical application doesn't work. Simple workaround is to run "xhost +local:" in the terminal first. This is documented in the GParted forum here: [SOLVED] How to run GParted on a GNOME on Wayland desktop http://gparted-forum.surf4.info/viewtopic.php?id=17446 This bug should be closed as a duplicate of bug 1274451. (But I don't have permission to do that). Thanks, Mike Fleetwood (GParted Developer)
