I have the same problem with a nvidia card (7300 LE), the problem is the same but instead of a black screen I get a white one. If I disable desktop efects from both user it works fine otherwise not. Even though a white screen shows when switching users you can type your password and enter and you will be able to login, but it is not what all we want, is it?
I hope my version of the problem can help solving the entire problem. Thanks in advance. -- log out or switch user results in crash https://bugs.launchpad.net/bugs/107115 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
