Hi ullix, I've forwarded your issue upstream to https://bugs.freedesktop.org/show_bug.cgi?id=23047 - please subscribe to that bug in case upstream needs further information or wishes you to test something. Thanks ahead of time.
Fwiw, without knowing a bit more about your setup, my guess is that gdm is using compositing or something, and isn't properly cleaning up its border rendering and is leaving those line droppings. In which case it might not actually be an X bug, but I've sent it upstream anyway in case it is. ** Bug watch added: freedesktop.org Bugzilla #23047 https://bugs.freedesktop.org/show_bug.cgi?id=23047 ** Also affects: xserver-xorg-video-intel via https://bugs.freedesktop.org/show_bug.cgi?id=23047 Importance: Unknown Status: Unknown ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: Undecided => High ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => Triaged -- [i945] two horizontal black stripes shown where top/bottom of login box was https://bugs.launchpad.net/bugs/406996 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. _______________________________________________ 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
