--- Comment #8 from Niels Ole Salscheider <niels_ole at salscheider-online.de> --- This sounds similar to https://bugs.freedesktop.org/show_bug.cgi?id=90340. Maybe you could try if the problem also occurs in your BIOS screen? I have found similar reports by windows users and it might really be some hw / cable issue. Apart from that it seems that most (all?) setups that cause problems have a screen with a 2560x1600 resolution... -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
