k. Nothing weird hardware wise with that then.

Is it using the Nvidia proprietary drivers, or the OSS nouveau ones?

If you're using the proprietary ones, which version?

Sorry for the 20 questions, am just trying to figure out where it might be going wrong. :)

555 554 something around that, I don't remember off the top of my head.

I might give nouveau drivers a go.

Ahh, it's probably the 545 or 550 drivers then. They shouldn't be causing issues either.

The nouveau driver is likely to have performance problems (compared to the official one), but if that's not an issue then it's worth trying. :)
