Re: lid switch on dell latitude d800 freezes system

Seems to me like there are two separate paths to follow, one of which
may only
be here because I haven't tested everything correctly -

1) work with nvidia and/or Dell - if loading the nvidia driver causes an
ACPI
interaction that locks the machine, it seems that it must be a vendor
thing.
I'd go with nvidia first just because they at least *try*, and might know
something, then maybe followup with Dell

2) work with the open source nv authors to see if they can work out DPMS for
the D800. This is where I might be ignorant, but I'm under the impression
screen blanking doesn't work with the nv driver and getting it to
work would
get a very effective power-save state on lid close combined with ACPI S1.
Obviously doesn't get you 3D, but I'd be quite happy if this worked

Mainly, I'm just glad I'm not crazy and someone else sees what I do :-).
I've
posted this on my D800 site, and I'll be happy to test and chronicle
anything
anyone finds out.

Thanks for putting in the effort to try and isolate this-
