Multiple monitors no longer configurable through settings in Kubuntu 12.04

[JW]

Kubuntu 12.04.4 LTS
Lenovo T510

Before a recent update, I was able to use the nVidia X Server Settings to configure my monitors. The "Display and Monitor" configuration has never worked for me.

After said update, the ability configure my monitors stopped working. In order to toggle between using only my laptop display or using my laptop display + external monitor, I need to log out (which of course refreshes the xserver...).

The following is the only system log I could find that seemed to apply to this. I repeated this a few times and watched the timestamps change on logs in /var/log, and only syslog and Xorg.0.log changed. Syslog only had entries about the vpnagent, so I'm guessing that's irrelevant. Here's the Xorg log:

Xorg.0.log:
