I tested lightdm-gtk-greeter instead of unity-greeter. In /etc/lightdm/lightdm.conf my system now has:
greeter-session=lightdm-gtk-greeter With this change the slowness is now gone. Therefore this bug seems to be in unity-greeter. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/945450 Title: Responsiveness: LightDM in ubuntu 12.04 very slow To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/945450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
