--- Comment #8 from conraid <conraid at linux.it> ---
The commit 2e7eeeb59a92d09144fdb7d2dc1af77a10a7945b does not solve the problem,
but "changing" the behavior of the display.
With this you do not need a supend/resume cycle, but just change tty to "wake
up" the monitor.

Without the line

.initial_config = intel_fb_initial_config,

in drivers/gpu/drm/i915/intel_fbdev.c instead it works.

I tried to apply, to the kernel 3.15, other commits in mainline, but I get a
compile error. Probably require changes to other parts of the kernel.

Kernel 3.14 and 3.16 it's ok in my system.
