Intel Arrandale IGP - screen does not light up on resume

Intel Arrandale IGP - screen does not light up on resume

[Eric Lacombe]

Hi,

I've got a problem with my laptop (powered by i7 Arrandale, it's a Sony Vaio 
Z11Z9E), when I resume from "suspend to ram" my screen does not light up. X 
uses the Intel IGP.
Maybe it is an issue with the driver of the IGP of the Core i7 Arrandale?

I currently use Linux 2.6.34, and have tested 2.6.33 and 2.6.32 (I see on 
google that there were some problems about Intel IGP and blackscreen. I was 
hit by them too at that time)

If you have any suggestions or if you want me to test any patch, I would be 
glad to do so.
Feel free to ask me any information I could provide to you about this problem.

Best regards,

	Eric

[BUG] ACPI/dynamic-hybrid-graphics (?) on Vaio VPCZ11 - screen does not light up on resume [was: Re: Intel Arrandale IGP - screen does not light up on resume]

[Eric Lacombe]

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 sony-vaio-z-series@lists.launchpad.net) 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
