I Have installed several video drivers from the software centre and I have installed the official driver from Nvidia.com and none of them show up in the additional drivers application. I did what this suggested but they still do not show Nvidia driver installed successfully, but not activated . The reason I am trying to use a different driver is because when I use the nouveau or the nvidia 331 driver I can't use my nvidia card, when I use the kernal and VDPAU 340 driver I get graphical glitches.

output of lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)

output of lspci | grep 3D 02:00.0 3D controller: NVIDIA Corporation GK107GLM [Quadro K1100M] (rev a1)

the intel card goes to the monitor port but the nvidia card is for rendering

To start off with, type lspci | grep VGA and take a note of your Graphic card model, just to make sure it is NVidia .

You are probably using the xorg open sourced driver right now and high resolution can create problems, as far as I'm aware.

To install the unofficial drivers, follow these steps :

Press Ctrl + Alt + F2 and login with your credentials. Now as root, run the following commands :

killall -9 lightdm (Unity)

or,

killall -9 kdm (KDE)

or,

killall -9 gdm (Gnome)

Now, type :

killall -9 Xorg

And run the following commands :

sudo apt-get --purge remove nvidia-current

sudo apt-get --purge autoremove

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

sudo apt-get update

sudo apt-get -y install nvidia-current

  • When I ran the purge commands, nothing was removed, when I did the update it could not find utopic packages from that ppa, when I installed nvidia current it only removed a driver I had installed. Note: I did not use your command to kill lightdm, I used sudo service lightdm stop. Jan 14, 2015 at 4:16
  • Have you selected all the packages in the Software Sources? Jan 14, 2015 at 4:23
  • So after I install a driver via software centre or a .run, I must select it in software sources? Jan 14, 2015 at 4:27

  • No. Not necessary to do it. Just make sure everything is check marked and perform the above steps. Jan 14, 2015 at 19:06
