Comment 41 for bug 1652282

It has been widely publicized at least since Fedora 25's release a year ago that GNOME on Wayland does not support running GUI apps as root. It has long been best practice for apps to not do this. Instead of trying to implement clever workarounds, app developers should follow best practice here.

Would you like to submit a patch for sudo? The GDM maintainer Ray Strode rightfully believes that it is wrong (i.e. Won't Fix) to have XWayland support running apps as root as long as Wayland does not. Therefore, someone will need to have a proposed fix for that issue first before worrying about XWayland.

At this point, I don't believe that Ubuntu intends to diverge from upstream on this issue, so to some extent, Won't Fix is appropriate here too. So fix things upstream instead of complaining to Debian and Ubuntu.
