I found the problem causing most, if not all of the mouse problems on LightDM: The Ambiance and/or Radiance themes. To fix the problem, install the Ubuntu Tweak PPA "ppa:tualatrix/ppa", install Ubuntu Tweak, and go to Ubuntu Tweak<Tweaks<Login Settings. Change the GTK theme to Adwaita. If not installed, please install this theme in the Software Center.
Hope this solved all of your problems :) ** Changed in: unity-greeter Status: New => Confirmed ** Changed in: lightdm Status: New => Confirmed -- 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/lightdm/+bug/945450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
