After taking the most recent update I woke and powered on to find my nvidia drivers messed up and lost my dual monitor support. Here's a permanent fix that should work for 18.04+.
Grab your device driver from Nvidia
Make your driver executable
$ chmod +x driver.run
Install depends (which should be installed by default on 18.04)
$ sudo apt-get install gcc & cmake
Blacklist the Nouveau drivers in kernel
$ sudo bash -c "echo blacklist nouveau >> etc/modprobe.d/blacklist-nvidia-nouveau.conf"
$ sudo bash -c "echo options nouveau modset=0 >> etc/modprobe.d/blacklist-nvidia-nouveau.conf"
Update Kernel with the Blacklist
$ sudo update-initramfs -u
Reboot
$ sudo Reboot
Terminal only login (perform at login screen)
$ Ctrl+Alt+F3
Login to the terminal only mode, then install Drivers
$ sudo telinit 3
$ sudo bash driver.run
