Description of problem: system-config-language can't be launched on a Gnome+Wayland session. Here's the output I get when launching system-config-language from terminal: $ system-config-language No protocol specified Unable to init server: Could not connect: Connection refused No protocol specified Unable to init server: Impossibile connettersi: Connection refused No protocol specified Unable to init server: Impossibile connettersi: Connection refused (system-config-language.py:5558): Gtk-WARNING **: cannot open display: :0 Version-Release number of selected component (if applicable): system-config-language-3.4.0-1.fc25.noarch How reproducible: Always Steps to Reproduce: 1.Open system-config-language Actual results: The tool crashes. Expected results: Ideally, the tool should work under wayland too Additional info: I set "severity" to low, since Gnome uses different tools in order to change system's language.
I can confirm the issue isn't reproducible on Gnome+Xorg. Setting this to block the "Wayland-related" tracker.
Probably related to: Bug #1274451 - sudo with graphical apps doesn't work on wayland Bug #1284222 - Application wont start on Gnome Wayland
so I tested the workaround suggested in bug#1274451 which is working fine. Execute this first xhost +si:localuser:root and then run this application.
I still have not got time to look how can this application be started under wayland without any extra settings.
Well, I am inclined to close this as WONTFIX based on the resolution provided for bug#1274451
