I am trying to install Xubuntu14.04 on my MSI GE72QC with NVIDIA GTX960M. After including nomodeset in the GRUB I install Xubuntu. I clik on download updates with the installation. Reboot does not work so I modify again the grub with nomodeset. Then I follow Ubuntu 14.04: nvidia drivers for GeForce GTX 960M that is I do sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get update sudo apt-get install nvidia-352 nvidia-prime sudo add-apt-repository -r ppa:bumblebee/stable
I would like then to see if the nividia graphic works. The suggestion I received in the installation is type glxspheres. I type glxspheres and I get : unknown command.
I guess this means that bumblebee is not installed. But since I loaded prime do I need to install bumblebee? If not how can I check that the nvidiadiver works? I thank you in advance for your help.
