I have a HP dv6t with the following graphics cards
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6730M/6770M/7690M XT]

Also when I run the command:
listed in these instructions.

cat: /sys/kernel/debug/dri/64/radeon_pm_info: No such file or directory
