Comment 30 for bug 576648

Hi, I've reported this bug(is the same bug):
https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/976443

I've found the solution, well a partial solution: To install driver from package provided by Nvidia, you must download it from its website.
To install the driver is necessary reboot the system and start in secure mode(modo de recuperación in Spanish, well the second option of grub, pardon my poor English) or terminal/console mode.
Give yourself root privilege:
sudo -s
Then go to location of downloaded file:
cd /path/to/file
give execution permission:
sudo chmod +x driverInstaller_or_downloadedFile.run
Execute the installer:
sudo ./driverInstaller_or_downloadedFile.run
Installer says that nouveau must be disabled, you must accept an continue the installation.

That works for me, but I did say a partial solution because the refresh rate is low, With nouveau or default installation of ubuntu that does not happen, my desktop was very clear.
