Sometimes I'll get the old behavior (max 1024x768), sometimes I'll get the correct behavior, and sometimes I'll have the video modes available but the display won't turn on if I select them. So I'm back to patching over the problem by commenting out the call to check_link_loss_status and its assignment to status in drivers/gpu/drm/amd/display/dc/core/dc_link_dp.c I'll report back after that. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
