Wayland? Can you run 'gparted' from a terminal and post the output?
Yes, on wayland. The output when gparted was run from the terminal: Created symlink /run/systemd/system/-.mount → /dev/null. Created symlink /run/systemd/system/boot.mount → /dev/null. Created symlink /run/systemd/system/proc-fs-nfsd.mount → /dev/null. Created symlink /run/systemd/system/run-user-1000.mount → /dev/null.

This is documented as a known issue with Fedora 26: https://fedoraproject.org/wiki/Common_F26_bugs#wayland-root-apps By design Wayland does not allow processes run as a different user to display on the desktop. Therefore using "su" or "sudo" to display a graphical application will not work. Simple workaround is to run "xhost +SI:localuser:root" in a terminal before running GParted. This is also documented in the GParted forun 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 1397103. (But I don't have permission to do that). Thanks, Mike Fleetwood (GParted Developer)
