Dual monitor set up in Ubuntu 7.10

Asked by Alycidon

I've just moved up from 7.04 to 7.10 and am struggling to get the desktop across two monitors.

I've a Dell Dimension 5000 with a ATI RV370 [Radeon X300SE] video card, and currently have two LCD panels connected - A Dell screen in the DVI port and a IIyama Prolite in the VGA port.

This all worked fine in 7.04 with the relevant section of xorg.conf set as follows...

It doesn't work in 7.10 though - all I get is the same image duplicated on both screens. Also, I can't configure the monitors using "Screens and Graphics", as the Screen2 option is greyed out.

I'm using the fglrx driver, and have tried removing and re-installing it to no avail.

Any ideas?

Thanks,
Alycidon

Ricardo,

Thank you very much - normal (dual screen) service has now been resumed ;-)
