All was well and then my installed NVidia drivers disappeared after a reboot. I am back to only one monitor and a resolution of 1024x768. I had 2 monitors available and with higher resolution.

Now I'm sure I can figure out how to install the Nvidia drivers et al since I figured it out in the first place. Ive just never had to do it after doing it already and having it disappear after a reboot, so Im asking the community:

  1. Is this normal?
  2. Best way to proceed to avoid it again.

I had several reboots where the driver stayed put. Things that may have changed is:

  1. I add a work space icon on the panel area at top and was playing with that, switching workspace etc.

  2. thee was the red warning icon on the panel, something about the cache didnt match something, so I did an apt-get update and then rebooted, and viola!

any help appreciated.

This problem happens when you install Nvidia drivers using .run files downloaded from Nvidia site. This is a wrong way to install drivers.

After each kernel upgrade you will have black screen or bad resolution.

The correct way is to install drivers from Ubuntu repositories or ppa.

You could install drivers by running

 sudo apt-get install nvidia-331

But first you need to uninstall the driver you have already.

sudo sh ./NVIDIA-Linux-x86_64-334.21.run --uninstall

As an option you can install latest driver from xorg-edgers ppa.

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-346
sudo add-apt-repository -r ppa:xorg-edgers/ppa

I recommend to remove one driver before install another, because sometimes some packages do not install when they are still running.

Full removal of Nvidia proprietary drivers can be done by

sudo apt-get purge nvidia*
