removed hal; how could i use accellerometers used by halevt before?

ahel · 2011-02-07 16:13:42

i have an Intel Classmate and when it is in tablet mode, thanks to its accellerometers, it was used to turn by this halevt configuration:

<?xml version="1.0" encoding="UTF-8"?>
<halevt:Configuration version="0.1" xmlns:halevt="http://www.environnement.ens.fr/perso/dumas/halevt.html">
<halevt:Device match="hal.button.type = tablet_mode">
    <halevt:Property name="hal.button.state.value">
        <halevt:Action value="true" exec="/usr/bin/cellwriter &amp;" />
    <halevt:Action value="true" exec="python2 /usr/local/bin/accel.py &gt;&gt; /dev/null 2&gt;&amp;1 &amp;" />
    <halevt:Action value="false" exec="ps ax | grep accel.py | grep -v grep | awk '{print (/^V/ ? $0 : $1)}' | xargs kill &gt;&gt; /dev/null 2&gt;&amp;1; /usr/local/bin/rotate.sh normal" />
    <halevt:Action value="false" exec="ps ax | grep cellwriter | grep -v grep | awk '{print (/^V/ ? $0 : $1)}' | xargs kill &gt;&gt; /dev/null 2&gt;&amp;1;" />
    </halevt:Property>
</halevt:Device>
<halevt:Device match="hal.info.udi = /org/freedesktop/Hal/devices/computer_logicaldev_input_1">
    <halevt:Condition name="ButtonPressed" value="brightness-down" exec="/usr/local/bin/cmpc-brn-down.sh" />
</halevt:Device>
<halevt:Device match="hal.info.udi = /org/freedesktop/Hal/devices/computer_logicaldev_input_1">
    <halevt:Condition name="ButtonPressed" value="brightness-up" exec="/usr/local/bin/cmpc-brn-up.sh" />
</halevt:Device>
</halevt:Configuration>

and by this accel.py script

but now without hal & halevt, what can i do?
can anyone be of some help?
because i can't really managed to solve this issue.
thank you all

Uhmm... is "reinstall hal and halevt" too obvious?
