I have installed Ubuntu 16.04 and at present I am using the graphics card: GeForce 8400GS. I would like to remove this card and instead replace it with GTX GeForce 980 Ti which I have.

  1. If I keep the current driver (for GeForce 8400GS), replace the graphics card then ubuntu won't boot up.
  2. I can't install the new driver (driver for GTX GeForce 980 Ti) without removing the current card.

What is the recommended way to changing the cards and the respective graphic drivers?

Thanks for your suggestions in advance.

    Search Additional Drivers in dash and use it to revert to the open source drivers (nouveau). It should work fine with the old card but may not with the new one (but chances are that it will). If so, you may need the nomodeset parameter until you install the (latest) Nvidia drivers for the new card. – user589808 Feb 10 '17 at 4:23
  • do what celticwarrior said but directly use nomodeset and change display drivers and reboot. no need to change drivers 2 times – Pavlos Theodorou Feb 10 '17 at 4:36

    You can install a new driver without replacing the card. – Pilot6 Feb 10 '17 at 15:29
  • @CelticWarrior There is no need to boot with nomodeset as you can do it an easier way. – Pilot6 Feb 10 '17 at 15:31
  • I tried @CelticWarrior's suggestion (without the nomodeset), it worked for me. Thanks! – user368823 Feb 11 '17 at 6:03

The easiest way is to install a new driver by

sudo apt install nvidia-367

Then turn off the computer and replace the card.
