Comment 10 for bug 744619

Thanks for that tip Michael. Sad, but after updating to 16.04 the problem persists. I can't seem to find a permanent fix.

I've also changed video cards (nvidia 960 now) so the vid card itself apparently wasn't involved. This is an upgrade install all the way from 12.04 if I remember correctly, so I wonder if it's a leftover setting of some sort that's screwing it up.

The other possibility for me that is different is I use LDAP authentication (using sssd now, but previously directly with ldap and pam) so I wonder if it's something in the underlying authentication system and gnome 3 that causes it. I'm the only person in the organization running Gnome 3, everyone else is on Unity and doesn't experience it.
