On 12.04 I used to utilize this procedure, to power off my ATI graphics and prevent my system from overheating, it worked fine. After installing 16.04, I've been trying everything I could find on the net, but no solution. My system runs extremely hot, causing the fans to run at max almost all the time. Can anybody come up with a little hack to shutdown that discrete ATI Radeon card?
System: HP Pavilion dv7-6190ed (FW F.18) [AMD/ATI] Whistler [Radeon HD 6730M/6770M/7690M XT]
