Currently testing Ubuntu 12.04 x64 for our development team. After upgrading from 11.10 I've been having video card issues. I'm using Nvidia GeForce GTX 460. When ever I try to launch Nvidia X server I get the following error message.
You do not appear to be using the NVIDIA X driver. Please edit your X configuration >file (just run
nvidia-xconfigas root), and restart the X server.
I've tried running sudo nvidia-xconfig multiple times and rebooting with no success. I've also tried getting the nvidia-current driver from the x-swat repo
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current
Followed again by a reboot did nothing for me but knock my resolution down to 800x600 Finally I've tried
sudo apt-get purge xserver-xorg sudo apt-get update sudo apt-get install xserver-xorg xserver-xorg-video-all sudo reboot
Does anyone have any thoughts or directions they could point me in? To the best of my understanding my video card is suppose to be supported.
