The RHEL bug report mentions that they have Xorg configured without RandR support. I do see a message in my logs that says gdm has RandR disabled for some reason: Nov 30 15:25:53 saturn /usr/lib/gdm3/gdm-x-session[3918]: (--) RandR disabled I'm not sure why gdm wants to run with it disabled. I don't seem to have a /etc/X11/xorg.conf file anymore... it's been quite some time since I've even had to edit Xorg config in recent Ubuntu versions. Seems like all this is managed by gdm-x-session now? ** Bug watch added: Red Hat Bugzilla #1250128 https://bugzilla.redhat.com/show_bug.cgi?id=1250128 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/911591 Title: gnome-shell crashes when resizing OpenGL window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/911591/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
