I upgraded from 10.10 to 11.04 and now my dual monitor support seems broken.
When booting, I see the screen duplicated just fine on both my laptop as my external monitor; after logging in, however, the external monitor disables and cannot be enabled.
Hardware:
- Dell Studio XPS 1640 laptop
- GFX: Ati Mobility Radion HD4670
- Extenal monitor: Acer P193W
I get the following error message when applying screen settings:
The selected configruiation for
displays could not be applied
requested virtual size does not fit
available size: requested=(3040,900),
minimum=(320,00), maximum=(1600,1600)

You're able to resolve that issue by removing .config/monitors.xml. Steps are: 1.rm ~/.config/monitors.xml in terminal 2.log out and log in 3.call monitors utility and setup your 2 monitor configuration again.
