Problem still exists in 13.10 64-bit lightdm version 1.8.4.0ubuntu1 Only restart of LightDM (sudo service lightdm restart) from a terminal (with Alt-F1) resolves the problem, but it also kills the running session.
Because this is such a long standing and basic bug (mind you: one only has to click the logged in user name and Switch User to run into it) I agree with J.C. Blouin that the importance should be higher. -- 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
