3 days ago I got installed Ubunto 14.04 and got some problems as fuzzy/blurry screen and bad support of multiple screens. So I realized that as default ubuntu install nouveau. 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:

nano /etc/modprobe.d/blacklist-nouveau.conf

…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

Please note that, nouveau drivers manual removal is required only if you are going to install the proprietary nvidia drivers yourself. If this is not the case then directly install the required graphic drivers from System->Administration->Hardware drivers. Its the recommended and the most convenient way available.

We'll blacklist all the culprit modules, remove all the nvidia* packages and as an extra step we may have to update the initramfs disk because it could be configured to load the modules at startup.

  1. Blacklist the modules. Open the blacklist.conf file.

    sudo vim /etc/modprobe.d/blacklist.conf
    

    add the following modules in the file.

    blacklist amd76x_edac #this might not be required for x86 32 bit users.
    blacklist vga16fb
    blacklist nouveau
    blacklist rivafb
    blacklist nvidiafb
    blacklist rivatv
    

    Save the file and exit.

  2. Remove all the nvidia* packages

    sudo apt-get remove --purge nvidia*
    
  3. Once you are done with the steps above, reboot, stop the display manager and try to install nvidia drivers.

    Press Ctrl+Alt+F1. Once you are in the text mode, stop the display manager. This will end all the applications, so you better close them yourself before completing this step.

    To stop the display manager use the following command

    sudo /etc/init.d/gdm stop
    

    gdm is for gnome display manager. If you are using kde then use kdm. If you are using lightdm as your display manager use sudo service lightdm stop

    Now, run the driver package that you downloaded from Nvidia’s website.

    sudo ./NVIDIA-Linux-x86-260.19.44.run
    

Note: If you still get the error related to nouveau drivers then you are probably required to update the initramfs disk. Probably it might be configured to load the nouveau drivers. Don't reboot or poweroff, run this command to update the initramfs disk.

    sudo update-initramfs -u

Now reboot and repeat the step 3. This time things should go smoothly.

Is there a way to do this during Ubuntu installation? I'm stuck on what appears to be an issue with the Nouveau drivers, see askubuntu.com/questions/507226/…. – Tyson Trautmann Aug 5 '14 at 21:45
    
Got unstuck after posting the question here (and replied to my own question with details on the issue). Thanks for checking in! – Tyson Trautmann Aug 6 '14 at 19:55

Thank for his recipe. Worked for me in Ubuntu 14.04, just 2 notes: to stop X needed sudo service lightdm stop (instead of /etc/init.d/gdm stop) and needed one more reboot after update-initramfs. – tomasb Feb 1 at 23:50
    
@tomasb good point on the lightdm - updated answer – Elder Geek Feb 2 at 0:10

I followed this link Ubuntu 14.04 install nVidia driver

and able to install nvidia driver. Follow the answer from Tez.
