Re: GeForce Go 7400 on Sony VGN-SZ1VP/C laptop
Your lspci output shows the following GPU:
00:02.0 VGA compatible controller: Intel Corporation Mobile Integrated Graphics Controller (rev 03)
Note, that's an Intel GPU, not NVIDIA. If you truly have an NVIDIA GPU in your system, its not appearing on the PCI bus, which is either a BIOS or kernel bug.
