I have installed 12.04 LTS as a Upgrade and even after waiting for that seemed to be a very long time to complete, I found the system to be unstable and for apps not to work.

So I decided to format and reinstall, but then it went from bad to worse. I am using an nvidia graphics card: when downloading the drivers it would seem to take for ever or totally crash. When I finally get it installed and setup my dual screen when I go to run Display from the Ubuntu menu it comes up with an error message saying:

Could not get screen information - RandR extension is not present

Can some one please tell me what I can do to solve this, or should I go back to 11.10 and give it time for the OS to find its feet.

Thanks for any help

IAN

You need to go to the synaptic package manager gui and search for libXrandr. BTW, are you running 32-bit or 64-bit Ubuntu? Which one you install, libXrandr.i386 or libXrandr.x86_64 is dependent upon that. Once done, you might have to reboot. Then you should be able to setup your display to handle the 2 screens.
