We're going to be moving natty to its new X stack within the next week or so. Currently this stack is available in xorg-edgers, and our testing is showing it to be quite stable.
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 ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Incomplete => New ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. https://bugs.launchpad.net/bugs/687445 Title: The strange white lines appeared on the top of screen _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
