Comment 16 for bug 1496163

Peter: Manually modifying the file per comment #9's fix worked for me on 14.04. But I am still having lots of problems with the GPUs on my laptop. Also had to use xorg-edgers ppa to get hardware acceleration back, otherwise X complained about unknown chipset. Also, the newest kernel versions (like 4.3) are freezing up hard for me, and different older versions only work on certain GPUs. What I mean is like, if I want to use the discrete nvidia GPU, I have to boot 3.19, but if I want integrated graphics, then I have to boot 4.2.4 with i915.preliminary_hw_support=1. Also, running "lspci" on newer kernels freezes the machine hard.
