--ZGiS0Q5IWpPtfppv Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable 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?
