Tried to install ubuntu 12.10 on that machine but failed. The kernel in the installation iso is 3.5.0-17, there is no i915-hsw module.

So I tried to do a fresh installation of 12.04.2. The xorg stack is lts-quantal. Without 2:2.20.9-0ubuntu2.3~precise1 in precise-proposed, this issue can be reproduced. After installing this package, this issue is fixed.

I installed ubuntu-12.10-desktop-amd64.iso into a usb disk on a non-haswell machine, then update kernel to a version which support i915-hsw, then use this usb disk to boot on a haswell machine, the ubuntu-12.10 can be successfully booted up.

Then i plugged a VGA to the machine test video switching, this problem can be reproduced. After upgrade xserver-xorg-video-intel to 2:2.20.9-0ubuntu2.3, the problem disappeared.

 So the xserver-xorg-video-intel for quantal was verified to be functional.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
