Vivid is still on 2.0.0 for this package so unless you're on Wily you'll need to grab 2.0.1 from: https://launchpad.net/ubuntu/wily/amd64/lightdm-gtk-greeter/2.0.1-2ubuntu1 ...or, if you're the adventurous sort, you can grab a daily as Andrew suggested above before the release was made.
This issue was also happening to me on boot, not just resume, with an external monitor connected (via VGA) in 15.04. Appears to be 100% fixed here as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448761 Title: gray screen shown when external monitor connected on resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1448761/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
