Hi, (the introduction is at the end of this one, it comes from a previous mail
sent to Zhenyu Wang)
I was thinking that it could come from bogus ACPI tables.
Someone said to me (from [email protected]) that with a
patched BIOS (that someone does and that I don't really want to test) that
allows to access a more advanced menu from my laptop, it will allows to have
the switch button (that switches between nvidia chipset and Intel IGP) behave
statically and not dynamically as it does now.
And it seems that with its laptop he was able to resume correctly from the
nvidia chipset.
I added Dave Airlie, as I know he played with hybrid-graphics (by the way
switcheroo make crashed my laptop)
I could send to you my DSDT if it could give you some clues on what screwed
things up. Just ask to me.
If someone has any idea, I could do some tests, try some patchs ?
And as always feel free to ask me more information if you need.
Best regards,
Eric

I find a way to light up the screen of my laptop after resume (but the solution
is not really satisfactory) :
When the resume step seems complete, I plug an auxiliary monitor through the
VGA connector, and the laptop screen light up immediately.
Any idea on the source of this problem ? and how to resolve it ?
Thanks in advance for your response.

For now I've got a workaround:
adding these 2 lines to my resume script makes the laptop monitor light up:
xrandr --output DP3 --off
xrandr --output DP3 --auto
