Hello, I am new to fedora
after installing fedora 29 on a multiseat system running 4 monitors.
gnome-shell is not starting and this is what I am receiving
Looks like an nvidia issue… How did you install the driver?
I suspect you’re testing something that hasn’t been tested before and finding some hole in the logic. (Itt might be related to mutter wayland doesn't support three 4k monitors on hybrid graphics system with proprietary driver (lenovo P70) (#205) · Issues · GNOME / mutter · GitLab - but I don’t think so.)
Getting a backtrace for the gnome-shell segfault would be the starting point - see StackTraces - Fedora Project Wiki - then I’d file a bug report against ‘mutter’ - Issues · GNOME / mutter · GitLab is the best place to file a bug report, but filing it in bugzilla.redhat.com against the fedora/mutter component would be OK too. The bug report should also include any relevant messages in the system logs (use journalctl.)
Sorry you are having this problem!
To add to this a bit: an easy way of getting the core dump would be coredumpctl dump gnome-shell -o gnome-shell.core, to write the core dump to a file named gnome-shell.core.
