hybrid graphics switching with open source driver

[Dukenukemx]

Been running Mint 16 on my laptop for a while, and haven't been able to switch between the two GPU's in it. One is a AMD HD 4250 and the other is a HD 5370. The system has 13.14 kernel with the latest oibaf drivers. I use Mate 1.8 UI with compiz.

I try the DRI_PRIME=1 command and some applications won't crash and some will. For example.

DRI_PRIME=1 glxgears

With this I get 1000 fps instead of 60fps by just running glxgeas. So I'm assuming it works. I also have no problems with Portal using this command. But...

DRI_PRIME=1 wine wow-64.exe

That will also always crash the application, and Mate. Bringing me back to the log in screen.

Is there an easier way to switch between the two GPU's, and why does it crash wine?

BTW, I figured out the problem to be related to the UI. Cinammon and Mate do not work well with hybrid graphics, but XFCE works just fine. So in XFCE the DRI_PRIME=1 does not crash me back to log in.
