I too have this same issue. I didn't know which package to report this bug to, but this seems to be the right place.
I dont know how hardware specific the issue could be like the OP suggested, as my computer is very different then his. I have an acer aspire 5553 with an AMD phenom processor and a Radeon HD4500 graphics card running the Open Sourced drivers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094571 Title: gnome-shell (or session) continually crashes/locksup when closing any window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1094571/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
