Could you attach a screenshot of how the output is corrupted at 1920x1080 please? Created attachment 52709 [details]
Good image: 1360x768
Created attachment 52711 [details]
Corrupted image: 1920x1080
Thanks for the prompt reply! I attached two photos: 1. A good image with 1360x768 2. The same image, but corrupted with 1920x1080 Best regards Bernd Jesse, do you have any ideas here? I managed to reproduce a very similar issue with android-x86 not that long ago, but it went away after a while. My best reference for such kind of problems is http://virtuousgeek.org/blog/index.php/jbarnes/2011/01/19/debugging_display_problems, so I guess you know where to start looking here. It looks like striding issue, something feeds wrong data to the 2nd pipe. Additional comment: I also tried with Debian stable (squeeze) now xserver-xorg-video-intel 2:2.13.0-6 But the problem remains exactly the same. It is my impression that the issue is the same as reported in bug 22996 ([945GM] external lcd does not work on high resolution) which leaves me rather hopeless because that bug is already around for 2 years. Regards Bernd Sure, the first step is grabbing a dmesg with drm.debug=0x6 from boot up until the time you connect and switch to the external panel at 1920x1080. We need the log Chris requested. Bug reporter seems to have disappeaered, closing. Please reopen with the request information if this is still an issue for you. |
