sudo gedit /etc/modprobe.d/blacklist.conf
and then I add
blacklist acer_wmiat the bottom of the blacklist.conf
DONE!

blacklist acer_wmiat the bottom of the blacklist.conf
Instead of downloading and installing the driver manually from Nvidia you should either use the xorg-edgers or xswat ppa for updated drivers.

https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
ATM xorg-edgers breaks Unity in 11.10 so I would suggest x-swat as a small stable option.
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get upgrade
