First: Sorry for my crappy paste of the ubuntu-bug information in my previous post.
Second: If I switch from unity to unity2d, the freezes do not occur; as the OP has problems with fglrx and I with nvidia (and others e.g. to be found at askubuntu.org with intel graphics) it seems that the context/opengl switches occuring during a user switch are causing the freezes. If there is anything I can do to provide more useful information please let me know. kind regards, Tom -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/886696 Title: Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/886696/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
