The "Oops" screen means that something marked as critical to the session
has not started, or has crashed repeatedly. There are only two critical
components in jessie's GNOME: gnome-shell, and gnome-settings-daemon.

Is there any indication in the systemd journal, /var/log/syslog,
or /var/log/Xorg.*.log of what has crashed or why? Please attach
the parts of those logs that are close to the time of the failure to
start GNOME.

Are you using the standard GNOME-Shell-based gdm login screen?
(grey background with a "texture", black bar at the top)

Are you using the standard GNOME Shell login session, or a variant
like Classic or Flashback?

The information gathered by these commands might also be useful
information for developers:

reportbug --template gnome-settings-daemon
reportbug --template gnome-shell
reportbug --template xorg
