I have this problem only after installing a clean Ubuntu 12.04.2. The new hardware stack (*-lts-quantal) is installed by default.
Here is a typical case to reproduce: 1) Only user A is logged in 2) Switch to user B via indicator (using HUD) -> Success 3) Switch back to user A via indicator (using HUD) -> Black screen I don't experience this bug on the original Precise hardware stack. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001221 Title: 12.04 black screen with blinking cursor when switching users To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1001221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
