Diagnose Gnome start up issues

I've had an issue for some time where after I login through GDM my screen goes blank and doesn't respond. The Gnome desktop never appears and I have to issue an Alt + SysReq + REISUB in order to reboot. Then, usually on the 2nd or 3rd attempt, the desktop appears normally. How should I go about debugging/diagnosing this issue?

Have you looked through the journal for errors?

Here are the logs before I rebooted:

Oct 26 20:11:50 4k systemd-journal[175]: Journal stopped
-- Subject: The Journal has been stopped
-- Defined-By: systemd
-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel
-- 
-- The system journal process has shut down and closed all currently
-- active journal files.
Oct 26 20:11:49 4k kernel: SysRq : Keyboard mode set to system default
Oct 26 20:11:29 4k colord[310]: /usr/lib/colord/colord-sane: error while loading shared libraries: libsane.so.1: cannot open shared object file: No such fil
Oct 26 20:11:29 4k kernel: usb 1-6: new high-speed USB device number 5 using xhci_hcd
Oct 26 20:11:14 4k kernel: nouveau E[   PFIFO][0000:01:00.0] read fault at 0x0002dcc000 [PTE] from CE2/GR_COPY on channel 0x00ff5c7000 [unknown]
Oct 26 20:11:13 4k colord[310]: Device added: xrandr-Samsung Electric Company-U28D590

So there is a pause after nouveau encountered a read fault and then another pause after colord couldn't find a shared library file.

Re: Diagnose Gnome start up issues

I think the issue is the nouveau drivers. I've switched back to nvidia and it's stable so far. The reason I switched away from nvidia in the first place was that Firefox had some stability issues. But that's better than the whole system freezing, so I'll stick with nvidia for now.
