Fix has been released, so you can get fixed version using update-manager. I've seen the gray blocks hang after installing the fixed package, but, as unggnu said, it's because of bug #141063 (xv related).
This particular bug (which happens even without xv video playback) has been fixed. -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
