Is this something that's planned for the future? A quick check of
relevant pages on the X.Org wiki doesn't have any mention of ACPI as a
planned/future/unfinished project.

I found that using the xrandr command to bring the resolution down to
1024x768 and _then_ using this key does work. Here's the remaining
problem: if I start X with the LCD running (and presumably without the
CRT attached as well) the X server automatically goes down to 1024x768,
the max. resolution of the LCD. 1280x1024 is not available to switch to
via xrandr if I connect the CRT later. Is there any way to have X make
this at least available for me to use if I connect my CRT after startup?

Thanks again,
Andrew
