Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have a laptop with a 740m graphics card and I've tried installing drivers from the additional drivers program from the system settings but when I activate and reboot the driver says it's not being used so that didn't work. My second option was to download directly from the NVIDIA driver website and run it from the ternimal via lightdm stop command and it gives me an error saying my GPU isn't support when I try to run it even though my card is officially supported on the NVIDIA website.

Should I continue intsalling the diver from the NVIDIA website even though it gives error messages or something else. Any help would be appreciated though i'm still new here :)

sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia

If you have 32-bit applications like Wine

sudo apt-get install virtualgl-libs:i386

Reboot or re-login to apply the group changes If you'd like to run a program on the nvidia card now, use the optirun program:

optirun firefox &
