Yesterday I got a new 22"W monitor to connect to my laptop and updated my kubuntu 7.10 to use the fglrx 8.1 driver.

The resolution of my laptop screen is 1400x1050, and the new monitor is 1680x1050.

I tried to configure a "big desktop" using the fglrx control panel, but it sets up both monitors as 1400x1050 (total of 2800x1050). I can not select "3080x1050". But, if I select "Analog Monitor (2)" from the fglrx control panel it says that maximum resolution is "1680x1050".

Do you know any way of making this work? All I want is a big desktop with native resolution. I do not need 3D acceleration. I do not mind changing to another version. I also tried the free driver but it doesnt make a big desktop at any resolution.

Thanks
