I have been having a problem where the screen 'blinks' twice every 5-10 seconds. The blink is like somebody is turning my monitor off 2 times quickly. I believe this is due to my graphics drivers, if not could anybody please explain what it is as I am a beginner to Ubuntu. I try to download the correct graphics card drivers but it comes up with a .run file and I am not sure what to do from here? I don't know how to install the drivers basically, if anybody could tell me it would be much appreciated.

To install the nvidia drivers, do the following:

  1. Open the program Terminal.

  2. Run the command sudo apt-get install linux-source.

  3. Run the command sudo apt-get install linux-headers-generic.

  4. Run the command sudo apt-get install nvidia-current-updates.

Reboot your computer. You should have the nvidia driver installed now. Normally there is an easier, graphical way to do it, but there is a bug that causes problems doing it that way...

Thank you very much :) – George Emerson Oct 19 '12 at 15:16
I just wanted to let you know that I have updated this answer. You may want to install the packgage linux-headers-generic, so that when we get a kernel update, your install isn't broken. Just run the command sudo apt-get install linux-headers-generic from the Terminal and you should be good to go. – rft183 Oct 23 '12 at 14:28
