[Bug 1652282] Re: GParted does not work in GNOME on Wayland

[Phillip Susi]

It appears to me that the issue is with gdm3.  Its man page says it is
supposed to create an XAUTHORITY file and set the environment variable
to point to it.  When running wayland, it does not do this and instead
relies on authenticating clients by the UID of the process.  It should
not be doing this.


** Changed in: gparted (Ubuntu)
       Status: Triaged => Invalid

** Summary changed:

- GParted does not work in GNOME on Wayland
+ Xwayland not using XAUTHORITY, prevents root applications from connecting

** Description changed:

- I have found that after switching from Xorg to Wayland on Ubuntu GNOME
- 16.10 with GNOME 3.22 that GParted does not run when I try to run it as
- root. That is when I click the icon and enter my password nothing
- happens. I have found that when running what is run when the icon is
- clicked that the output in Terminal is (gparted-pkexec):
- 
-     Created symlink /run/systemd/system/-.mount → /dev/null.
-     Created symlink /run/systemd/system/boot-efi.mount → /dev/null.
-     Created symlink /run/systemd/system/boot.mount → /dev/null.
-     Created symlink /run/systemd/system/run-user-1000.mount → /dev/null.
-     Created symlink /run/systemd/system/run-user-120.mount → /dev/null.
-     Created symlink /run/systemd/system/tmp.mount → /dev/null.
-     No protocol specified
- 
-     (gpartedbin:16832): Gtk-WARNING **: cannot open display: :0
-     Removed /run/systemd/system/-.mount.
-     Removed /run/systemd/system/boot-efi.mount.
-     Removed /run/systemd/system/boot.mount.
-     Removed /run/systemd/system/run-user-1000.mount.
-     Removed /run/systemd/system/run-user-120.mount.
-     Removed /run/systemd/system/tmp.mount.
- 
- So I am now unable to launch and use GParted as root which is really the
- only way I can run it in order to make changes.
