OK, so I tried on a jessie VM with jessie kernel and it gave me a 
backscreen.

I updated to the kernel from bpo (4.2) and now gdm is starting properly.

How can I verify if the issue you got is now fixed? I see this in the 
Xserver logs:

[KMS] Kernel modesetting enabled.

BTW, without qxl kernel driver, I see some ugly yellowish vt.
