Since Ubuntu 12.04 LTS has been released I have no luck at all with this release on my desktop or laptop. I've looked all over the internet and I see allot of other user having problems aswell. I had release 11.10 64-bit running on my desktop without any problem. But with 12.04 I have issues with my Geforce GTX850. The dual screen settings don't take effect as it should. On my primary screen I have everything working fine, but on the second screen I have a grey backbground, no wallpaper, and it doesn't feel like it's working at all. I have tried to uninstall the Nvidia drivers but that doesn't work either because then the whole system freezes on me.
I have version 295.40 installed of the Nvidia driver.
