3 days ago I got installed Ubuntu 14.04 and got some problems as fuzzy/blurry screen and bad support of multiple screens. So I realized that Ubuntu installs nouveau as default.
I googled how to remove this driver and install Nvidia driver. I found this guide:
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates apt-get update
Then, you install the nvidia driver:
apt-get install nvidia-current apt-get upgrade
Now that nvidia is installed, you need to blacklist the nouveau driver so it don’t pop out when you will reboot. Create or edit the following file:
…and add these lines at the end:
blacklist nouveau blacklist lbm-nouveau options nouveau modeset=0 alias nouveau off alias lbm-nouveau off
I checked via the software & updates if nvidia driver got installed successfully and it display me now that the driver that is installed is nvidia 304.117
than I tried to run:
lshw -c video | 'configuration'
and the result is that the driver is still nouveau.
configuration: driver=nouveau latency=0
