I tried using some nvidia drivers on Ubuntu 16.04. But they prevented my machine from booting, so I went to the console and used this to purge nvidia:
sudo apt-get remove --purge nvidia*
However, I can now only set my screen display to 1600x1200. My monitor supports 1920x1200, but I don't see that option anymore under the screen display settings.
Under additional drivers, I am using X.Org X server - Nouveau display driver from xserver-xorg-video-nouveau (open source).
How can I use 1920x1200 resoltion again?
Is this useful?

In the Screen Display settings, it thinks I have a Built-in Display. But I do not. I have an external monitor.

EDIT: Update...
I managed to fix this problem by going to the NVidia website directly, downloading the driver for my graphics card, and installing it. In this case, I downloaded a file called NVIDIA-Linux-x86_64-375.26.run and installed it.
Unfortunately, I have still ended up with a problem when the machine alternately boots successfully, and freezes when asking me to unencrypt my hard disk, which I have asked as a question here: Ubuntu 16.04 Boot Alternates Between Freezing and Working
I've had this issue with the nvidia drivers before. The open source drivers work better for me. Reboot into the multi user mode target and pass --uninstall to the installer package to uninstall the driver. Upon reboot you should be able to use all your old resolutions.
The fix was to reinstall Ubuntu and follow these instructions:
