Sod it, we’ll try going with the driver you downloaded from the nVidia website first…
OK, first thing you need to do is make sure you’re completely up to date, and add a couple of packages
So open a terminal and run these commands in sequence:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
When that last command completes (and leaves you back at an $ prompt) REBOOT ← this is important to load any new kernel that came with the updates
Once rebooted, open a terminal and run:
sudo apt-get install linux-headers-generic build-essential dkms
OK, now write the next instructions down (or have them on another PC) as you’ll not have a graphical front end whilst installing the drivers.
Hit Ctrl+Alt+F3 … this will drop you to a text console (black screen with text).
in the console, log on by typing raxial and hitting enter
then enter your password and hit enter.
Once logged on and at an $ prompt, run these commands in sequence:
chmod +x /home/raxial/Downloads/NVIDIA-Linux-x86_64-340.32.run
sudo service mdm stop
sudo apt-get purge nvidia*
sudo sh /home/raxial/Downloads/NVIDIA-Linux-x86_64-340.32.run
and follow any onscreen instructions.
When that finishes (if the system hasn’t already rebooted), run:
sudo service mdm start
to restart the desktop.
DO NOT delete the installer file (NVIDIA-Linux-x86_64-340.32.run) yet … we may need it to uninstall the driver if anything goes wrong.
And remember … Linux commands ARE case sensitive.
If that all goes well, and you’re now back at the desktop, open a terminal and post the output from:
sudo lshw -C display
so I can check if it’s using the correct driver now.
