--- Comment #5 from Ryan Bourgeois <[email protected]> 2012-07-11 05:18:34 PDT --- Created attachment 64094 --> https://bugs.freedesktop.org/attachment.cgi?id=64094 drm.debug=0x04 during screen reset I've attached the output of dmesg during a screen reset with drm.debug=0x04. It looks like DRM is receiving a hotplug event indicating that the connector eDP-2 has been unplugged. This disconnects the display. Then nouveau, seeing that eDP-2 has been force enabled, reconnects the display. So now I'm fairly certain that solving the disconnected connector issue will fix the every-9-seconds screen blanking.
