[Intel-gfx] intel-drm-nightly broken on 835GM

[Thomas Richter]

Hi Daniel,

finally had access again to the Fujitsu laptop with the 835GM chipset. 
This time, I checked up the nightly-built branch based on the 3.12.rc4 
kernel. Similar to the 3.11 kernel, I get a blank screen during login, 
i.e. gdm does not render its graphics. The boot console, even after 
loading the i915 module, does appear, is however vertically misaligned. 
The first line(s) of the console do not show.

When booting with an external monitor connected, the internal DVO locks 
up, and the signal on the external monitor is flickering left and right, 
as already described. gdm does not render on the internal panel, and the 
external panel remains black.

Thus, 3.12rc4 drm-nightly works (unfortunately) as bad as the 3.11 and 
is not usable.

Greetings,
	Thomas
