My laptop runs on Ubuntu 13.10 and has NVIDIA GT 520MX discrete graphics. But Additional Drivers in Software & Updates shows that 'No additional drivers are available'. Why is it so? How can I install the correct driver?

  1. Download the Nvidia driver if 32bit here else if 64bit here
  2. Install the driver manually This link will help you
  3. To install it manually

First press ctrl + alt +f1 This will open tty1

Now you are using the tty terminal console

log in with your user name and password

Now stop the lightdm(dgm or whatever) using the command

sudo stop lightdm

Then install the new driver with

sudo sh /path-to-the-driver
  • if something goes wrong close the installer and reboot then try again
  • still same problem the nvidia installer will make a black list in /etc/modprobe.d/
  • if this is not generated you have to make such file to black list nouveau
  • Run sudoedit /etc/modprobe.d/nvidia-graphics-drivers.conf and fill it with this: blacklist nouveau
  • If the problem is not solve you have to add the string "nomodeset" to your /etc/default/grub, in GRUB_CMDLINE_LINUX_DEFAULT= line
  • then update the grub

    sudo update-grub

But my discrete graphics has OPTIMUS technology. I could find out that OPTIMUS is not officially supported in Linux. What should I do in this context? – sid Dec 23 '13 at 14:39
