* Monitor is a DVI monitor connected to an active mini-displayport to DVI adaptor. * Output to all three screens functions in Windows. * dmesg output and xrandr output are able to see the display and print out the correct supported resolutions * HDMI and DVI output are functioning correctly on the card. * Using xrandr I'm able to get the X server to think that the display is present and functioning. (I can place windows and the cursor on the screen) * The display is in power-saving mode from the moment that the framebuffer console initializes. I'm not able to get any image on it.
