[-- Attachment #1 --] Hi, I've been trying to work out why my ASUS ZenBook can't work with S3 sleepstates. Resume works theoretically like a charm (I suspend with music playing; the music stops and continues upon wakeup; I can reboot the system). One thing that does not, however, is VGA resume. The screen will just stay blank. So I looked into it a little and realized -- what's the expected behaviour towards video reset when multiple VGA cards are present (NVIDIA Optimus) with vgapci0 being the (unusable) NVIDIA board and vgapci1 the (usable with Xorg, vt(9), KMS etc) Intel one?
