[Debian-eeepc-devel] Bug#566707: eeepc-acpi-scripts 1.1.9: SHE-ENGINE toggle not working (eeepc 1000h/1000he) - A POSSIBLE SOLUTION

This suggests that Fn-Space causes an ACPI hotkey event but no ACPI button/*
event. (Most keys, I find, cause both.)

That's how the script determines which event type to ignore. (While I'm
presently seeing them occurring hotkey first, I've seen that second. Which is
a bit of a problem, since I don't think that it's yet safe to assume that
we'll always get button events – consider backports.)

Well... something which I missed in your initial report has helped: Fn-Space
has hotkey code 00000039, which matches the "SHE button" on other models.
AFAIK, this only produces a hotkey event, but you can check this by running
acpi_listen and pressing Fn-Space.

If you'd included "diff -u" output rather than the whole script, this would
have been spotted sooner...

Regardless of whether one or two events are generated, the attached patch
should fix things.
