If you do rule out a client app, or otherwise want to continue exploring it as an X issue specifically, here's the next step.
We're going to be moving natty to its new X stack within the next week or two. Currently this stack is available in xorg-edgers, and should match almost exactly what will soon be in natty. I'd like to have you attempt to reproduce your issue with this new stack. If it still occurs with that stack, we can then take the the bug upstream, or approach the kernel team or other appropriate groups about it. The PPA is available at: https://launchpad.net/~xorg- edgers/+archive/ppa Here's a simple way to install: sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get upgrade Then reboot your system to get to the new bits. If you want to go back to stock Ubuntu, there is a corresponding ppa-purge tool: sudo ppa-purge xorg-edgers sudo apt-get update sudo apt-get upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/681054 Title: screen repeatedly goes black for a fraction of a second -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
