Brand New Alienware M17xR3 with Intel i915 IGP, and NVIDIA GT 460M
video.
New, Clean installation of Kubuntu 11.04. When booting up, and BEFORE
Xorg starts, the video mode switches and the video on the screen
flickers and switches rapidly between colors as it flickers. No text or
graphics are visible on the screen after that, just the flickering.
Disabling modeset for intel (kernel command line parameter
i915.modeset=0) stops the flickering and I get to a desktop. When doing
this, screen resolution is wrong and vgaswitcheroo is disabled, but at
least the computer is functional.
