gnome-shell appears to only log a couple of relevant lines at most on start-up (`journalctl /usr/bin/gnome-shell`):
org.gnome.Shell.desktop[1893]: glamor: EGL version 1.4 (DRI2):
gnome-shell[1893]: GNOME Shell started at Tue Jun 06 2017 09:38:50 GMT+0800 (AWST)
Not enough information to be useful for debugging peoples' GPU and monitor start-up issues.

One of the most important things we miss is the JS backtrace.
It will be soon possible to enable it by adding
SHELL_
And even better by appending also ":backtrace-
I suggest to enable this in 17.10, and in 18.04 (till beta, at least) to get better logging in case of crash events.
