To remove rather than fix .. Login using a rescue CD, mount your disks, enable networking and drop to root. Then remove Bumblebee bee using one of the methods (I'd purge) below and reinstall Nvidia 331.

/etc/bumblebee.conf needs to be edited... if you do not use nvidia-current (-> nvidia-331) there should be no /etc/X11/xorg.conf of any kind sudo update-alternatives --config i386-linux-gnu_gl_conf and sudo update-alternatives --config x86_64-linux-gnu_gl_conf (or the mac equivalent) should be set to mesa.

Instead of Bumblebee, you could try nVidia's proprietary drivers, which have been added Optimus support to. Open the Software & Updates utility, and navigate to the Additional drivers tab. It will take some time to load, after which you'll be presented with a list of drivers known to work with this device. By default, the open source noveau driver will ...

I had the same kind of problems, but I added the http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu and they are much quicker to solve problems with drivers then the standard Ubuntu repositories... I currently have the 346.16 driver installed and that did away with all that flickering...

I know from bitter experience that at any given time there are several nvidia drivers available and each one has its own pros and cons. I learned that after I "upgraded" to a later version only to spend hours putting it back the way I had it the first time. I admit I'm not clear about your wishing to switch it off. I think what you need is the nvidia ...

@Ryan, you don't actually describe what happens when you have Optimus enabled in the BIOS when starting Ubuntu, but obviously it doesn't work. My guess is that your laptop is like mine (Lenovo T430), where the Intel GPU has access to the the internal display and a VGA port, and the Nvidia GPU has access to the internal display and the two DVI ports. I'm ...

If you don't have the option to switch GPUs in the BIOS then it's quite likely you have a muxless laptop, where the Nvidia GPU doesn't have direct access to the internal laptop display, and where it wouldn't make sense to switch off the Intel GPU. Apart from the BIOS, there is a the vga_switcheroo command, which allows one to change which GPU acts as the ...

A couple of things: Firstly, you should let xrandr do all the work, and get rid of any 'xorg.conf'. Secondly, you need to understand which ports are connected to which GPU, which you can also use the xrandr command for. I'm guessing from the fact you weren't able to get it working out of the box that the internal laptop display is only available from the ...

Up until 2013, nVidia didn't have any plans to support optimus technology in Linux. That's the reason project Bumblebee had started. But in May 2013, nVidia started providing partial support for optimus tech on Linux and it has been quite some time. But Bumblebee has evolved a lot and is officially supported by Ubuntu since Ubuntu 13.10. You can head over ...

What has so far worked for me with all computers that uses Nvidia drivers I've run the additional drivers program and tested the various ones that it finds and stick with the ones that gives me the best performance.

The conflicting version 3.2.1-90~trustyppa1 is coming from the stable PPA. Unless you need some specific feature from that version you could remove the PPA and use the version that comes with utopic by default: sudo ppa-purge ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee-nvidia

I've been having the same difficulty getting my GT 750m to be recognized by Ubuntu 14.04 and 14.10. After many different drivers, and many restarts, I came across this on the NVIDIA web site that might explain why some of us are having so much trouble: Note that the list of supported GPU products is provided to indicate which GPUs are supported by a ...
