Forwarding this Ubuntu bug from Mario Limonciello: https://bugs.edge.launchpad.net/ubuntu/+source/xorg-server/+bug/385658 [Problem] Similar to bug #19545, the 9400M G (pci id 0866) needs support. Tested with 2.1.14-2ubuntu2 (WW) NV: Ignoring unsupported device 0x10de0866 (C79 [GeForce 9400M G]) at 03@00:00:0 [Original Report] Testing out the daily image from June 10 2009, the live cd is not booting up to X. It is falling back to failsafe graphics mode. This is because it's selecting the NV graphics driver rather than VESA. The Studio XPS 1340's graphics cards are NOT supported by NV and are not called out in the PCI ID files in /usr/share/xserver-xorg/pci.

For some additional background... This particular hardware has dual cards. Previously when we saw this issue in Jaunty we patched xserver to force xserver to select the first pci video device, which worked when we were using the pci.ids approach for detecting hardware. However, now that we're not using pci.ids files to detect the hardware, this issue has cropped up again. But for this particular bug report I'd like to focus on the core issue that support seems to be missing for the video card. Gaining that support would obviously be the ideal solution to this problem.
The regression is in the X server, and is being addressed by the PCI boot device sysfs query work. C79 indeed doesn't work yet; there's some hardware initialization step that's missing that I haven't yet managed to track down, so it's not as simple as just adding the PCI IDs. Adding NV driver support for this GPU would not fix the server regression that prevents it from picking any GPU when there are more than one. *** This bug has been marked as a duplicate of bug 19545 ***
