A get-around is to specify 'pci=noacpi' on the boot up command - when this is done, the 'intel' driver is correctly loaded. $ Xorg -version X.Org X Server 1.10.4 Release Date: 2011-08-19 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.24-29-server i686 Ubuntu Current Operating System: Linux thich 3.0.0-15-generic #26-Ubuntu SMP Fri Jan 20 15:59:53 UTC 2012 i686 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.0.0-15-generic root=/dev/sda3 ro quiet nosplash Build Date: 19 October 2011 05:09:41AM xorg-server 2:1.10.4-1ubuntu4.2 (For technical support please see http://www.ubuntu.com/support) $ lspci | grep "VGA" 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/805700/comments/15 ------------------------------------------------------------------------ On 2012-02-13T08:23:56+00:00 Tybion wrote: Created attachment 56947 Successful load of 'intel' driver when 'pci=noacpi' is specified at boot up Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/805700/comments/16 ------------------------------------------------------------------------ On 2012-02-13T08:35:26+00:00 Tybion wrote: Other info about this bug .. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/805700 http://markmail.org/message/msojtkj4o4klho3t?q=lkml+list:org.kernel.vger .linux-kernel Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/805700/comments/18 ------------------------------------------------------------------------ On 2012-02-13T11:06:44+00:00 Chris Wilson wrote: Lets have lspci -n with a normal boot and pci=noacpi, and see how the device is configuring the PCI device layout in both cases. From the description this sounds like it is going to be an [kernel] ACPI bug... Jesse, do you have any clue as how invoking ACPI might rearrange or hide the display controller (on a gen3 device so no hybrid gfx involved)?

I could understand how we would fail if the device disappeared due to pci=acpi, but if it is present for both I need a new explanation. Can you please attach the dmesg for your boot in both cases? Adding drm.debug=0xe to your kernel boot parameters would be useful, but I don't think required. My next theory is that the i915.ko failed to load in the pci=acpi case, and so the ddx found no kms support and did not initialise. Looking at the dmesg should confirm that and if so give the next clue.

I may be important to note that it doesn't occur with all intel 82945G/GZ chipsets, at least according to my searches (example http://askubuntu.com/questions/81076/issue-with-text-in-a-intel-82945g-express-chipset-family). It could be linked to Foxconn motherboards, maybe even those including intel Atom processors. Tybion, is it also your case ?
