Black screen on Ubuntu 12.10 with Intel i915 video
Booting Ubuntu 12.10 on a box with Intel i915 video, the screen goes black early in the boot process and remains so. Details are these:
The box in question is a new HP 1000-1210LA laptop. "lspci | grep ]VGA" identifies the video chipset as "Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)". Running Smolt from an OpenSUSE live CD further identifies it as an Intel i915. A web search shows the correct driver is provided by xserver-
Whether booting 12.10 from live media or from a hard disk install, booting without kernel parameters results in the screen going black early in the boot process. Seconds later I hear the bongo system ready sound, indicating that the box is booting. A workaround is to boot with the kernel parameter "acpi=off": video works as expected, although of course without the ACPI features one expects on a laptop.
Searching the web, I located and tried numerous suggestions, none of which worked on this hardware. The kernel parameters video=LVDS-1:d, video=LVDS-1:e, noacpi, console=tty1, and i915.modeset=0 all silently failed, as did removing the default parameter "splash". Likewise this advice to modify grub's settings also failed with no change:

For what it's worth, the Mageia 2 live CD exhibits the same symptom. In Mageia's case, the kernel parameter "xdisplay=vesa" resolves the issue without sacrificing ACPI. This would be an acceptable solution here; I don't anticipate needing anything beyond the basic vesa driver in any case.
What else might I try to get video working on this laptop?
