[Bug 551358] Re: [Lucid] blank screen after gdm login intel 945GM works with nomodeset

[Davidiam]

I had same issue until I saw this error using kernel 2.6.31 in the kernel.log ;
i915 0000:00:02.0: LVDS-1: no EDID data
fb: conflicting fb hw usage inteldrmfb vs EFI VGA - removing generic driver

so did a search on google and found that the framebuffer that the kernel has for default is the "efifb" and that i915 or inteldrmfb was trying to by the fb , then seens I had to customized my dstd and change the cpu to atom following this http://ubuntuforums.org/showthread.php?t=1341580 
 I downloaded the source for 2.6.32 recompile my kernel with the option  CONFIG_FB_EFI=NO and also but sure if necessary CONFIG_DRM_I915_KMS=NO and then add the kms manually in grub kernel options as i915:modeset=1. 
And now my screen is correctly detected no more errors of EDID nor conflicting fb.
