Hi,
Are there statistics about the number of X server crashes in Fedora?
From my experience, the X server crashes far less often than gnome-shell.
Best source for such data is bugzilla, something along these lines:
Xwayland: https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGN...
Xorg: https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGN...
gnome-shell/mutter https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGN...
This can certainly be improved, for example, filter the gnome-shell/mutter bugs that apply to Wayland only.
HTH, Cheers, Olivier;
