I have this problem, too. All I can think of adding is that it only happens when you are trying to return to the first user that logged in, and it doesn't matter which user it is.
I've set identical permissions to two users, and have done the following: Log into userA; switch to userB; wait on B; log out userB; blank screen. I repeated that swapping the users, and got the same result. Log into userB; switch to userA; switch back to userB right away (this works fine); wait on B; log out user B; I get to the user login screen as per normal function. This means I cannot just log in and then walk away leaving stuff unfinished, because my other user could log in for a few minutes, and then I'd be left with an unusable session :( If it's any use to have more logs or other files posted, I'd be glad to do so. -- Switch user -> Log out -> Black display until reboot https://bugs.launchpad.net/bugs/560911 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
