After setting up 11.10 today, I seem to be having problems with my dual monitor set up. It worked without issues in Mint but today after I switched to 11.10 only one monitor seems to function.

This seems a little odd to me. During setup both monitors functioned without issue, although they were mirroring each other both monitors but as soon as it booted into Unity my secondary monitor stopped working.

I checked under settings->display and the second monitor doesn't seem to even be detected. On the off chance it had something to do with drivers, I upgraded the proprietary drivers to the latest version with zero success. If anyone has any ideas, I'd love to hear them.
