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
