I always feel stressed when updating or switching to proprietary drivers, because it has crashed my Ubuntu before. Unity is a little slow on my system. Can switching to a new version of proprietary drivers speed it up some day?

Generally it is a smoother experience (depending on which Nvidia card you have) although the Nouveau driver is definitely improving.

Have you/are you willing to try unity-2d? It should run much more smoothly for you


Generally speaking the window manager itself does not perform better, but the applications do. This is most notable with any graphics intense , 3d application or games.

I try to stay with the open source drivers for the same reasons you do.

If the open source driver is causing you a problem, try the nvidia driver, you can always revert.



Yes, in my proprietary driver is smoother than open source driver. Extremely on games/3d applications.

I have not any problem on installing Nvidia proprietary driver!
Following procedure is what i used for installing Nvidia driver:

  1. Download appropriate current driver from NVidia.com
  2. Copy downloaded driver into Desktop
  3. Right-click on it and under Permissions tab active Execute check box
  4. Press Ctrl+Alt+F1 to switch to tty1
  5. Loggin and stop LightDM service using sudo service lightdm stop
  6. Goto desktop folder and run Nvidia driver using following commands: (notice that my Nvidia driver is NVIDIA-Linux-x86_64-285.05.09.run)

    cd ~/Desktop
    sudo ./NVIDIA-Linux-x86_64-285.05.09.run
  7. It will notify you to problem on installing driver and will asks you to uninstalling Nouveau driver. Also it will asks "Do you want to disabling Nouveau driver?"
    Let it to do that.
    Again it will prompt you to unsuccessful installation. Don't worry, it is OK... reboot your machine using sudo reboot
  8. Now your resolution is 800x600. It's OK.
    Repeat step 4 ~ 6 and complete installation procedure and let it to auto configure X
  9. Reboot or start LightDM service using sudo service lightdm start command

Enjoy! :)
