I have the same problem with my 900x3e. The first line of the screen is white, also when I reboot. When I completly shut down the laptop the line goes away for a few minutes and then comes back. When xubuntu is fully booted the line is only about 1/5 of full screen width, starting left.
It also happens once to me that I saw a line at about 200 pixels from top while surfing the web. But this line disappeared after a few minutes. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1162408 Title: little horizontal black lines sporadically appear To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1162408/+subscriptions _______________________________________________ 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
