Nvidia Drivers

This will be a step-by-step tutorial on how to Install NVidia drivers, enabling SLI (if applicable) & control the GPU-fan speed at start-up.

1. Installation of Drivers

2. Enabling SLI

3. Fan control at boot

INSTALLATION OF DRIVERS:

For installation of STABLE drivers, add the following PPA to your system

CODE:

deb http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu trusty main
deb-src http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu trusty main

CODE:

sudo apt-get update

CODE:

sudo apt-get upgrade && sudo  apt-get dist-upgrade

Once everything is done, close it out and open up your “Driver Manager” and select the version you want. STABLE = nVidia-352.63 –You can select nVidia-352-updates, if you want to… but it’s less stable.

Once you’ve chosen, let it install and complete (this may take a few minutes) then reboot when completed.

A. In terminal run:

CODE:

sudo nvidia-xconfig

B. In terminal run: CODE:

sudo nvidia-xconfig --cool-bits=12

C. In terminal run:

CODE: SELECT ALL

sudo reboot

D. Once booted, run:

CODE: SELECT ALL

sudo nvidia-settings

E. Click on x-server and set up your display(s), then apply.

F. Click “save to x-configuration file.

G. Click THERMAL SETTINGS under your video card

H. Click AGREE, scroll to bottom, then close.

I. Adjust fan to desired speed.

J. Close settings window & terminal.

SETTING UP SLI

  • begin by getting everything closed out, so your DE is running.
  • open your terminal, and enter

CODE:

sudo nvidia-xconfig --sli=On

A. a new xorg.conf will be created… this is normal. Accept the new build and continue. B. Once that’s done, enter

CODE:

sudo reboot

C. After reboot, open your file-browser (nemo) and head to /etc/X11 D. As root, open xorg.conf and in (Section “Screen”) change SLI from off to On. (big O, little n) E. Save and close the file.

FAN CONTROL AT START-UP:

— If you have done all of the above in this tutorial, then you do not need to do the first step in this section.

A. In terminal run:

"sudo nvidia-xconfig --cool-bits=12"

B. Navigate to ~/.config/autostart/ now create a document named “nvidia-fan-speed.desktop”

C. open the file with a text editor.

D. so there are no fowl-ups, copy and paste the text below into the file.

E. replace XX with the fan speed you would like. 10-100, numerical value only, no percent sign needed. CODE:

[Desktop Entry]
Type=Application
Exec=nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUCurrentFanSpeed=XX"
X-GNOME-Autostart-enabled=true
Name=nvidia-fan-speed

F. To add in the second GPU-fan, add the code below into the file.

CODE:  
[Desktop Entry]
Type=Application
Exec=nvidia-settings -a "[gpu:1]/GPUFanControlState=1" -a "[fan:1]/GPUCurrentFanSpeed=XX"
X-GNOME-Autostart-enabled=true
Name=nvidia-fan-speed

G. save and exit the file.

H. log out of your system, then back in.
