Description:
I upgraded my system this morning, and after rebooting I could no longer access the second monitor. According to Xorg.0.log:

(WW) NVIDIA(0): TwinView requested, but only 1 display devices found.

Running both nvidia-settings and xrandr also only found the one monitor. I "fixed" the problem by downgrading back to nvidia-180.51-1, nvidia-utils-180.51-1, and kernel26-2.6.29.4-1. I believe that the problem is with the new nvidia driver, but it could also be with the kernel upgrade. I had to upgrade/downgrade both at the same time due to dependency issues, so I was unable to test them independently.

Additional info:
* nvidia-180.51-1
* nvidia-utils-180.51-1
* kernel26-2.6.29.4-1
* xorg.conf file is attached for reference

Steps to reproduce:
1. configure nVidia card for dual-monitor access using TwinView with the 180.51 drivers (or earlier) and kernel 2.6.29 (or earlier)
2. upgrade to the new 185.18.14 drivers and 2.6.30 kernel
3. reboot and try to start X
   xorg.conf (1.3 KiB)
This task depends upon

Please report this bug upstream, we can't patch it.

@Gerardo: it is only useful to keep open reports in "Upstream Bugs" for bugs that we can fix by applying a patch before new upstream version is released (e.g. Gnome apps).
