I found a mainline kernel in below link, and I install the headers and
linux-image-extra at the same time.

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.7.30-quantal/linux-image-3.5.7-03050730-generic_3.5.7-03050730.201402120735_amd64.deb

But after build the drm-dkms-i915, it was failed when build the module.

implict declaration of function 'intel_enable_gtt'

So I checked the header file, it's a little difference.

So currently I can't install the drm-dkms, any idea? Thanks!
