Alternate Method to Enable Experimental Open GL Driver?

[JNK123]

When I try to enable the experimental OpenGL driver using raspi-config in the terminal, I receive this error message:
"Driver and kernel not present on your system. Please update"
Followed by, "There was an error running option AB GL Driver"

Raspbian is up to date, but I am using Berryboot to dual-boot Raspbian and OpenELEC. I suspect that this is the reason I cannot enable the Open GL driver. (Before using Berryboot, I could enable the driver using raspi-config)

Is there any alternate method to enable the experimental Open GL driver?

I apologize if I've left out any important details, I'll provide any additional information if necessary.
Thanks in advance for your help!

I'm sure this was in the release blog, but that down the blog list now.

Look in the config.txt and probably overlays

Thanks for the reply, however I managed to solve the issue.

I tried using NOOBS to dual-boot instead of using Berryboot, and it was no longer an issue.

Problem solved.
