ubuntu is getting good at bundling vendor graphics drivers so having to download and install manually is not necessarily the go to solution. Try this : System Settings -> Software & Updates -> Additional Drivers give it time to do its probes/lookups and it will respond with list of pre-loaded drivers from which you can pick an Nvidia if you ...

You need to have both Nvidia proprietary drivers and nvidia-prime to get it working. This can be done by running sudo apt-get install nvidia-346 nvidia-prime for Ubuntu 14.04 and 15.04. Then you will have Nvidia X Server Settings in Dash. And there you can find PRIME profiles.

First of all to get much trusty results, glxspheres is better than glxgears. You can use "vblank_mode=0" for get higher results but it is all about v-sync. If you can run a program with optirun command there is no problem to worry about because your Nvidia card works. You know that your Nvidia card is working but don't know working fine or not, for that ...

I had the same problem. Just delete Bumblebee sudo apt-get purge bumblebee* And then just say "hello!" to Nvidia-Prime sudo apt-get install nvidia-prime After selecting your graphic card from nvidia-settings, (intel or nvidia) you should log out and come back. (Unfortunately after every changes)

Glxgears is not good for benchmark, you should use glxspheres instead. There results similar in my system but no need to worry there is no problem. Compare two card with glxspheres and check that you have a problem or not. To install glxspheres: Download VirtualGL (.deb) from: http://sourceforge.net/projects/virtualgl/files/VirtualGL/ Navigate to the ...

Good news. I found a solution. In order to launch VLC through Bumblebee without errors - VLC must be installed BEFORE Bumblebee. P.S. I tested it two times on Ubuntu 14.04
