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 Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1001221 Title: 12.04 black screen with blinking cursor when switching users Status in “lightdm” package in Ubuntu: Confirmed Bug description: When switching users on 12.04 it will sometimes just go to a black screen with a cursor. The user switching to is not logged in yet. Expected behavior: Click current user up top> from the drop-down click the user wanting to log in > brought to the lightdm log in screen and log that user in Instead: Click current user up top> from the dropdown click the user wanting to log in > brought to a black screen with a blinking cursor From here, you cannot type or initiate any keyboard shortcuts other than Ctrl +Alt+F(1-6) to reach tty1 etc, or Ctrl+Alt+F7 to return to the user that you were originally trying to switch from. Ctrl+Alt+F8 will bring you back to the black screen. This happens pretty often so I should be able to test anything needed. Thanks!
