Now Nvidia with Optimus and glfrx and Bumblebee works fine here.

I want to stay with kernel 3.5.0.22 and not being automatically updated again.

You can lock packages to a certain version. The terms that will help you find something on google should be dpkg hold package. I'm sorry but I don't remember the syntax. –  nikhil Jan 27 '13 at 11:01

There is no need to do that, because you can switch back to the older kernel 3.5.0.22 in the Grub menu. At boot you can show the Grub menu by holding the shift key. If you want you can select the desired kernel as default kernel.

Yes, you can if you don't uninstall the kernel. –  BuZZ-dEE Jan 27 '13 at 9:50
