--- Comment #7 from Shobhit <shobhit.kumar at intel.com> ---
>From your uploads, it is clear that pipe framecounter is running so the display
pipe is not stuck and actually enabled. With backlight also enabled, don't see
why display should not work.

Can you stop the GDM/LightDM from ssh and use either test_display from i-g-t or
modetest and see if you get some test pattern on the screen.
