nouveau

Hi I've just installed Ubuntu 13.10 on a Lenovo w350 and am having some issues with graphics driver.

standard nouveau drivers work great on the laptop display but when I attach an external display it goes bad on the external monitor, seems it's not re-drawing properly. (Photo attached).

I've tried other drivers but none of them detect the external monitor when connected.

Any ideas?

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K1000M] (rev a1)

UPDATE 1: I have noticed that if I leave the System Monitor open the display improves. Wierd.

UPDATE 2: If I leave a video going the lag/flicker issues stop.
