Bumblebee 3.2 is officially released. It has lot of new bug fixes and two new features. Very soon the new packages will be available (PPA for Ubuntu, etc.).

One new feature is to start optirun without any render bridge (-b is added), useful for nvidia-settings command (optirun -b none nvidia-settings -c :8) . Second feature is the --no-xorg option for optirun to disable starting secondary X server. This is handy for CUDA or OpenCL applications that do not need the graphics rendering capabilities.

Release notes can be found here:

You can try to install the new Nvidia Beta drivers, 319.12, but is currently not advised (it can cause lower performance). However the new driver is supported and will not break Bumblebee, it will be auto-detected.

Have fun!

The --no-xorg feature is great! I use bumblebee just to run CUDA computational code, so I will use this a lot.
I am going to try it on 13.04, can't wait.
A question for anyone:
When I install, will all the kernels get the Module? I need to be able to use it with 4 different kernels--> 3.8.2-ck1, 3.8-6.dmz.1-liquorix-amd64, 3.8.0-19-generic, and 3.9.0-rc8. I am testing for Oz Unity. 
I'm just worrying about Nvidia Driver on my Alienware,and I see the good news. Thanks for helping Linux growth.
Great project indeed, incredible that you find all technical specs for it. Curious whether dual screen support is still being improved?
So I'd like know if is possible has some control about temperature, because I'm facing some troubles when I'm playing games with wine. My laptop is overheating about 95ºC and shutdown...

When you are playing games using the discrete video card, it becomes hotter, this is normal (because the discrete video card is working hard & the card is NOT in 'stand-by' mode). However overheating is never the intention.

Bumblebee makes it only possible to use the card, it isn't overclocking any hardware or something, so it doesn't matter if you are using Windows, Linux, Mac or....

My first guess is to clean your laptop, remove all the dust. There are special high pressure sprayers on the market for cleaning laptops/computers. Also it is possible that your laptop hardware is broken, causing overheating problems.

Good luck!
