<code bash>

''/etc/udev/rules.d/100-mount-videos.rules''
<code ->
ACTION=="add", ATTRS{idVendor}=="0a81", ATTRS{idProduct}=="0101", RUN+="/home/your_username/bin/mount_videos.sh"
</code>


Exemple : 

<code ->
lsusb |grep -i touch
Bus 001 Device 009: ID 04e7:00c0 Elo TouchSystems
</code>


''/etc/udev/rules.d/100-touchscreen-calibr.rules''
<code ->
ACTION=="add", ATTRS{idVendor}=="04e7", ATTRS{idProduct}=="00c0", RUN+="/bin/bash -c 'echo /usr/local/bin/touchscreencfg.sh |at now'"
</code>

Je ruse en uilisant **at** car l'appel directe au script ne fonctionne pas ( le ''xinput list'' ne fionctione pas)


''/usr/local/bin/touchscreencfg.sh''
<code bash>
#! /bin/bash

export DISPLAY=:0

NAME=$(xinput list  --name-only |grep -i touch | grep -iv ' pen')
ID=$(xinput list --id-only "$NAME")
SCREEN=$(xrandr 2>&1 |grep ' connected primary' |awk '{print $1}')
/usr/bin/xinput --map-to-output $ID $SCREEN
( sleep 5 ; /usr/bin/xinput --map-to-output $ID $SCREEN ) &
</code>
