Bug Description
I have an Acer AL1916W monitor with a maximum resolution of 1440x900 and an ATI Radeon X1600 video card.
I have installed the fglrx driver, and it appears to be working. The monitor is available in the list in the configuration window - it didn't appear on the live cd (presumably because it was added in a recent update). However, when I select it and click "Test", I either get a distorted screen (if I don't check the "widescreen" box) or an "Input not supported" error message (if I do check the "widescreen box"). The same problem occurs if I choose "Plug and Play" or "LCD Monitor 1440x900".
Output of "ddcprobe":

It is possible to get the monitor resolution working using "sudo dpkg-configure xserver-xorg", as is true with previous versions of Ubuntu.
I am using Ubuntu 7.10 Gutsy beta with the updates as of October 7.
