Hi, I would report you a bug with displayport and radeon module on recent linux kernel. When my card is plugged with displayport I have the following error in dmesg and screen stay black. [ 18.493734] [drm:dp_link_train] *ERROR* clock recovery reached max voltage [ 18.493735] [drm:dp_link_train] *ERROR* clock recovery failed [ 18.510279] [drm:dp_link_train] *ERROR* channel eq failed: 5 tries [ 18.510280] [drm:dp_link_train] *ERROR* channel eq failed
When i plug my screen with (dell 27" 2560*1440) a DVI cord everything is fabulous. This was tested with 2.6.35-rc3, 2.6.34, 2.6.32 and all is revelent. I've also tested with a patch from here : http://comments.gmane.org/gmane.comp.video.dri.devel/46851 but nothing change. My test was done with a debian sid/experimental disto. # lspci|grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4550] # uname -a Linux sluttrin 2.6.35-rc3-seblu #5 SMP Mon Jun 14 15:43:18 CEST 2010 x86_64 GNU/Linux # dpkg -l|grep -e radeon -e mesa (16:47)[2] ii libdrm-radeon1 2.4.21-1 Userspace interface to radeon-specific kerne ii libdrm-radeon1-dbg 2.4.21-1 Userspace interface to radeon-specific kerne ii libgl1-mesa-dri 7.8.1-2 A free implementation of the OpenGL API -- D ii libgl1-mesa-glx 7.8.1-2 A free implementation of the OpenGL API -- G ii libglu1-mesa 7.7.1-3 The OpenGL utility library (GLU) ii mesa-utils 7.7.1-3 Miscellaneous Mesa GL utilities ii xserver-xorg-video-radeon 1:6.13.0-2 X.Org X server -- AMD/ATI Radeon display dri ii xserver-xorg-video-radeon-dbg 1:6.13.0-2 X.Org X server -- AMD/ATI Radeon display dri ii xserver-xorg-video-radeonhd 1.3.0-3 X.Org X server -- AMD/ATI r5xx-r7xx alternat ii xserver-xorg-video-radeonhd-dbg 1.3.0-3 X.Org X server -- AMD/ATI r5xx-r7xx alternat II can provide more information on request and offer help testing patches.
