I got something very similar, but for me it only crashes when I have the window with the video is between the workspaces (note I got the effect that makes workspace switching smooth, so a window between the workspaces can be seen from both)
I got a ATI Radeon 9800 graphics card. I also have not installed it's closed driver. -- X session crashes when switching workspace and video playing https://bugs.launchpad.net/bugs/147537 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
