I have a AMD A6 5400K (with integrated AMD 7540D graphics) - Socket FM2 (trinity). I am using the propriety AMD driver (fglrx 9.0) on Ubuntu 12.10

I know (and have checked) that AMD Cool n' Quiet is working properly for CPU but how would I go about power management for the integrated graphics?

I have experimented with the radoen driver before on another system which used the low, auto settings etc via command line - how do I go about it with fglrx?
