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.
- 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)
