[Bug 556253] Re: [2.6.32-19 regression] Does not check lid status any more, external screen powered off

[Bryce Harrington]

Seems my concerns about this were justified -

The upstream change feels like one of those that makes sense "in theory"
but doesn't take all hardware configurations into account.

Martin, to isolate g-s-d, remove your monitors.xml file (in .config
somewhere).  If that is not present, AFAIK g-s-d will not attempt to do
any changes to your system.  If that makes the problem go away, then
this bug should focus on g-s-d.

Otherwise, perhaps reverse-quirks in the kernel are needed.  I might
even suggest backing out the upstream patch, and sticking with
individual quirks.  Quirking individual systems means a lot of work, but
at least it's well understood how to recognize the problem and
incorporate the quirk.
