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

[Phillip Susi]

No, you misunderstand.  Wayland applications running as root work just
fine under Wayland.  It is X11 applications that do not work, and the
reason it does not work is because gdm misconfigures Xwayland.  The gdm
man page says it does one thing, but it in fact does another, therefore,
it is broken.


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

** 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):
+ When running wayland, GDM fails to set up an XAUTHORITY file and instead
+ relies on the process UID for authentication.  This prevents
+ applications run as root, like gparted or synaptic from connecting to
+ the server.  GDM needs to set up the XAUTHORITY file when running
+ Xwayland just like it does when it runs the conventional Xorg.
  
-     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
+ A large list of applications broken by this can be found here:
  
-     (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.
