    nvidia broken following kernel update?

    I have an Ubuntu laptop, which I use with a second monitor via a docking station. The laptop, dock and external monitor are all Dell products. After accepting updates from update-manager this morning, which included a kernel update plus the subsequent reboot, my external monitor was no longer automatically used by Ubuntu (in addition to the monitor built into the laptop).

    At least since installing 12.04, I have been using NVIDIA X Server Settings to switch between single and dual monitor mode. However, now when I open NVIDIA X Server Settings I get the following message.

    "You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server."

    I ran nvidia-xconfig and ran "restart lightdm" as root and using sudo. Neither fixed the issue. I have rebooted the computer. That didn't solve the problem.

    I tried copying an old xorg.conf file that I had backed up while using 11.10 over /etc/X11/xorg.conf and restarting lightdm. That doesn't work, either.

    Should I be purging reinstalling NVIDIA related packages? How do I get past this issue?

    I think you have to rebuild the NVIDIA module and reinsert it into the kernel. In other words, reinstall the driver through the NVIDA package.
