Configuring Xorg as the default GNOME session
Wayland is the default GNOME display server, and has been the default in Fedora since Fedora 25. However, users may still need to use the older Xorg display server for compatibility reasons.
To confirm the current windowing system in use, go to Settings and select About.
Configuring GNOME to use Xorg
At the login screen, select the "gear" icon and select GNOME on Xorg.
Once login is completed the X11 windowing system will be in use, as can be seen by returning to Settings > About. This change will persist unless changed back at the login screen.
Changing the default GNOME session via configuration file
As an alternative, this change can be made by editing a configuration file
/etc/gdm/custom.confand uncomment the line:
Add the following line to the
Logout or reboot to enter the new session.
With the above changes applied, the option to set the GNOME session to use Wayland will actually be removed from the "gear icon" menu on the login screen.
