[Pkg-acpi-devel] Bug#579554: acpi-support: power.sh is not run if power adapter is unplugged while system is on standby

[John Lindgren]

Package: acpi-support
Version: 0.133-2
Severity: normal

Hi,

Normally /etc/acpi/power.sh gets called when I plug in or unplug my
laptop's power adapter.  Thus, I have edited the script to dim my screen
when the laptop is running on battery power.  (In the good old days this
was done in hardware.  Ah well.)  If, however, I am using the laptop at
my desk, put it in standby mode, unplug it, carry it with me somewhere
else, and then turn it on again on battery power, the system does not
"notice" (so to speak) that it has been unplugged, so the screen remains
at full brightness.  Since actual ACPI events will obviously not be
generated while the system is on standby, I think the system should
check what the power state is when it is turned on again and
run /etc/power.sh if the state has changed.  Alternatively, please
provide a script that is run when the system is powered on from standby
so that I can copy my script to dim the screen there.

Thanks for your consideration.

John Lindgren
