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.

No you do not have to install bumblebee - nvidia-prime is the replacement to switch the GPUs.

Use the NVIDIA X Server Settings application (Prime Profiles) to switch between the two GPUs.

In case this does not work, uninstall every NVIDIA related software ... so - boot your computer ...

When the GRUB boot menu appears : Highlight the Ubuntu menu entry and press the E key.
Add the nouveau.modeset=0 parameter to the end of the linux line ... Then press F10 to boot.

When the login screen appears press Ctrl+Alt+F1.

Update : Enter your user name and password - then execute :

sudo apt-get install ppa-purge
sudo apt-get purge nvidia* bumblebee  
sudo ppa-purge ppa:bumblebee/stable
sudo apt-get update
sudo reboot  

Now install the latest available official stable NVIDIA drivers 358.16 from the short-lived branch.

When the GRUB boot menu appears : Highlight the Ubuntu menu entry and press the E key.
Add the nouveau.modeset=0 parameter to the end of the linux line ... Then press F10 to boot.

When the login screen appears press Ctrl+Alt+F1.

Update : Enter your user name and password - then execute :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-358 nvidia-prime
sudo reboot

  • hello I did the procedure a first time. I gos a system error and then I restarted the installation from scratch. at the installation of the nvidia-358, i got the following error message : cannot find nvidia-358. I then used nvidia-352 instead. when rebooting after purgin xorg repository I had a system error regarding Xorg. This error was filed. – piscvau Dec 1 '15 at 18:18
  • Then I did sudo aptitude safe upgrade. The result is not too good : in primeprofiles, I cannot choose to use the intel graphic card. it is not possible to modify . Aslo it is not possible do put the computer so sleep or hibernation. – piscvau Dec 1 '15 at 18:18
  • To make it easier for you to understand I changed the order of instructions and updated the answer. Important : You do not have to purge xorg ! In the original answer I said that you should purge the xorg-edgers PPA (in case you added it before). Now I implemented the purge command for the bumblebee PPA ... and again : you only have to purge the PPA in case you added it before and did not already remove it. :) – cl-netbox Dec 1 '15 at 18:57
  • I re installed every thing from scratch and applied your sugestions in the right order. The nvidia-358 is founded but the installation does not terminate properly : during the update intramfs I get an error message regarding "not syncing" and a panick kernel. I then rebooted and it is not possible because the efiboot file is corrupted!... – piscvau Dec 1 '15 at 20:06
