So now that i have everything else working on this x230, I'm taking a
fresh look at the acpi brightness support.
I'm in the same boat - only PEG works. But I have integrated graphics
only, rather than both integrated and nvidia graphics.
A cursory reading of the linux acpi and video /
Not sure that it did :)
I tried it once early on, and it concerned me enough I never tried
again. It was clearly in a violently erroneous state!
At one point, X *could* resume the display. This makes me think the
problem is solved via the graphics chip state, but it could be an
acpi thing.

Hi!
Hm, resurrecting this thread, I'll try this on my X230 tomorrow and
see if it makes the (non-xorg, console only) video work on resume.
If it does, what will it take to automatically determine that this
kind of work-around is needed?
Thanks!

I'm glad you got this working, it makes the X220 (and probably
other laptops with similar issues) more usable on FreeBSD.
Sure, that's good news !
I'll have to bring my X220 back up to current and start
looking at sleep issues next.
Great !

I got this to work by using 4 backslashes. At that point the patch

That's awesome! I've

vgapci's ivar is set by the PCI address. Do you have multiple vgapci devices?
