Running Ubuntu 3.2.0-53-generic, and attempted to upgrade the proprietary Nvidia drivers from 304 to 319. It failed to reboot, hanging with a blinking cursor and the "could not write bytes: Broken pipe" error at random.
This was resolved by logging into tty and running the following:
sudo apt-get update
sudo apt-get purge nvidia-*
sudo apt-get install-nvidia-current-updates
It now boots to the desktop (Cinnamon 1.8.8), but when checking the Additional Drivers tool, it states the 304 Driver is activated, but not currently in use. The glgears tool results in 10,000fps and there are no 3d Unity issues.
I found the following page for instructions about resolving, but would like to confirm the appropriate steps forward to resolve. This is my second Ubuntu installation; the first attempt was wrecked by installing a new graphics card (different brand) and breaking several dependancies trying random "fixes" found on the various support forums. I learned to stick with Synaptic for installing/upgrading packages after that exercise.
I abandoned Windows XP on my latest build earlier this year to avoid Win7/8. The linux command structure/usage is still new, so baby steps would be greatly appreciated. Thanks in advance.
