Hello,
Thanks for replying.

I added the option, however i915 driver seems to not recognize it, please see
below:

dmesg | grep i915

[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.13.0-74-generic
root=UUID=9bb8b128-9495-4667-9cda-1048bd45abd9 ro quiet splash
i915.enable_ppgtt=0 vt.handoff=7

i915.enable_ppgtt=0 vt.handoff=7

[    2.325629] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor

What is the purpose of enable_ppgtt flag? Do I need to upgrade to different
i915 version?

Thanks
