Binary package hint: acpi-support

When using KMS on intel, the /usr/share/acpi-support/screenblank script
is called on a lid closure event which unconditionally locks in KDE the
screen via this -

elif [ `pidof dcopserver` ]; then
        dcop kdesktop KScreensaverIface lock
fi

This has a side effect of causing a unrecoverable hang approximately 1
minute after the lid is closed currently. If you open the lid before
about 45 seconds or so in it will recover fine, but waiting longer will
result in having to reboot. Removing this action from the script makes
it work correctly.
