[Pkg-acpi-devel] Bug#558820: acpid repeatedly invoking acpi_fakekey upon opening laptop lid; makes system unusable

Package: acpid
Version: 1.0.10-4
Severity: important

When the laptop lid is opened (or maybe closed? Can't figure), acpid
starts repeatedly spawning acpi_fakekey through /etc/acpi/videobtn.sh,
which renders both X and console almost unusable. Killing acpid brings
the situation back to normal.

Under X, the mouse cursor jumps around, windows take a lot of time to
redraw or react to user input, etc. Under console, "^@" character
keeps appearing, probably because of the keypress being injected via
acpi_fakekey. It makes login impossible (however, if an user is
already logged in, the system is usable enough to kill acpid).

My laptop model is Compaq Presario CQ60. I don't have any other laptop
to see if the bug isn't hardware-specific.

This started to happen after upgrading from acpid 1.0.10-3.
