Ok, the device is configured differently to how I was expecting. It uses SDVO to drive both LVDS (which I should have guessed given the drivers report of 2 LVDS). At first glance, we think we are driving both panels, i.e. we've attached a crtc to each and a bound the fbcon framebuffer to both crtcs, yet only one panel is active. The likely suspect is inside intel_sdvo.c. A different adventure than the one I was anticipating. Perhaps this will be my wayland test bed... -Chris -- Chris Wilson, Intel Open Source Technology Centre
