This question was marked as an exact duplicate of an existing question.

I recommend to download and install the driver from nvidia directly. Following steps are necessary:

  1. Download the latest linux driver for your card from Nvidia

store it in a folder, e.g. /tmp/

Close all running programs and save all changes to any open documents!!!

  1. Switch to plain text console (CTRL + ALT + F1) and log in as normal user

  2. make the .run file executrable with:

    chmod +x /tmp/

  3. stop the graphical window manager:

    sudo initctl stop gdm

  4. install the driver:


Follow the instructions - warnings might appear but usually can be considered harmless

  1. restart the graphical window manager:

    sudo initctl start gdm

  2. switch back to workspace by pressing CTRL + ALT + F7 or F8

(replaye NVIDIA### by the original filename of the file downloaded)s
