I see it calling drm_helper_connector_dpms(connector, DRM_MODE_DPMS_ON) from radeon_connector_hotplug when I plug in the cable, meaning HPD sense said there is something connected. How to investigate this potential conflict with userspace? Because, as I originally wrote, without X running monitor comes back fine. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
