Bug#595033: xserver-xorg-video-ati: Only one display works at a time with RV620 [FirePro 2260] with two DisplayPort output
Hi, This bug was fixed in the package 'linux-image-2.6.36-trunk-amd64'. But I just install the package 'linux-image-2.6.37-trunk-amd64' and this issue about dual 'DisplayPort' happened again. Maybe there is a regression in this new kernel release? Do you need any logs file? Best regards, Thomas PIERSON signature.asc Description: This is a digitally signed message part.

After that if I run for example : xrandr --output DisplayPort-0 --left-of DisplayPort-1 I have a black screen on the 2 monitors and I can't access to a terminal. I noticed something else : When I turn off and on again the second monitor (manually) an kernel error occurred : [18515.140220] [drm:radeon_process_aux_ch] *ERROR* Buffer to small for return answer 1 6 During some seconds, the main monitor get stranges color and lights intensity! It seem to be the same problem that the bug #569970 but I am not sure. Someone have an idea to solve this? Tell me if you need other logs or informations. Please try the 2.6.35 kernel from experimental. Cheers, Julien signature.asc Description: Digital signature
