Title:
[HP Pavilion dv7-4272us] Display glitches occur
Status in xorg package in Ubuntu:
New
Bug description:
Display glitches occur every time the display changes from the IGD to
DIS, and vice versa.
I'm trying to _keep the DIS GPU *turned off* in order to save power
and keep this laptop cool.
I can't tell who keeps turning the DIS GPU back on, but I'd love to know how
to keep the DIS GPU locked OFF.
