Re: IGP 8300 freezes with 177 and 180 on ubuntu
I've had problems with my M3N78-EM (similar board, same chipset) related to its USB support. My Razer Lachesis USB mouse would freeze either immediately or shortly after X started.
I bought a USB 2.0 PCI addon card for 10 bucks and plugged my mouse into that. That solved my problem. Maybe you could try that, or try unplugging all USB devices, use an old PS/2 keyboard, launch X, and see how it goes. I don't have a problem with my USB keyboard plugged into the motherboard's USB port though.
