I have this awful issue when running dual monitors with this set up. I get the worst kind of performance/lag, and im not sure what the problem is. When I disable either of the monitors in the display settings, I get exceptionally fast performance so it's either something with the GPU drivers, or the computer itself not being able to handle it?

8 gigs of ram
3.4 ghz Quad Core cpu

The monitors:
1440x900 19" LCD monitor @75hz
1680x1050 LCD monitor @60hz

Could the issue be related to both monitors being a different refresh rate? I didn't see a place where i could change the refresh rate in ubuntu.

I'm currently using the open source tested drivers. When I used the proprietary ones, it wouldn't let me set up two monitors outside of mirror mode.

Set both monitors to the same resolution and refresh rate. plus its Ubuntu, so I'd say driver support is not like Windows. I'm no Ubuntu guru so I can't really help you, but this quick google looks promising
