[Macchiato] Asus GT710 graphics card

[Stuart Monteith]

I’m using linux-image-4.15.0-arm64 from straight Debian buster. It is using X, rather than Wayland.

I find that the speckling is very much less when I turn off the compositor in Xfce.

The modprobe options I find work are:
   options nouveau noaccel=1 runpm=0 nofbaccel=0 modeset=1

Setting noaccel=0 results in a black screen.

I never saw any speckling in any case. I believe the runtime PM is disabled by default or at least that’s what my sysfs lead me to believe.
