I don't think I understand your question. Optirun is a program, "dhgs" is a
technology term. when you run a program with optirun it will use nvidia
otherwise by default it's intel. But I rarely use it. (Basically I just use
bumblebee to turn off nvidia) Because I can't see the diff if a firefox is
running under nvidia.  Besides it drain battery makes system hotter(these
are 2 weakness of the first generation i core. I wish sony could ve made
Z1, not Z2, with later generation i core.)

Strange why I could not even enter the ubuntu 14.04 before....
