Hi,

I've been trying to work out why my ASUS ZenBook can't work with S3 sleepst=
ates.

Resume works theoretically like a charm (I suspend with music playing; the =
music
stops and continues upon wakeup; I can reboot the system).=20

One thing that does not, however, is VGA resume. The screen will just stay
blank.=20

So I looked into it a little and realized -- what's the expected behaviour =
towards=20
video reset when multiple VGA cards are present (NVIDIA Optimus) with vgapc=
i0=20
being the (unusable) NVIDIA board and vgapci1 the (usable with Xorg, vt(9),=
 KMS etc)
Intel one?

Best
Johannes
