I also have a Dell XPS 15z laptop with 1920 x 1080 native resolution (which I currently cannot use), so when I stumbled here, I thought it was the solution I needed. I am trying to get this to work with kernel version 3.8.2 but I cant get past the first step. I can add the extra info to grub
But if i take out
i915.i915_enable_rc6=1 i915.lvds_downclock=1 i915.i915_enable_fbc=1 pcie_aspm=force
the boot freezes with the message:
I should mention that I could only see this message adding
[Firmware Bug]: ACPI(PEGP) defines _DOD but not _DOS
to the grub command line. Otherwise, the screen just goes dark and "frozen".
Most posts I see about this "freezing during boot" problem consider the problem "solved" by adding nomodeset to grub. I don't call that a solution at all since it leaves me stuck with VESA.
Thaks in advance,
