+<h2>Coupure microphone X220</h2>
+<h3>2021-05-09</h3>
+<p>Dans mon Thinkpad X22O fonctionnant sous Manjaro i3, la bouton de coupure du micro est
+désactivée, car il n'est pas pris en charge par thinkpad-acpi.<br>
+Pour l'activer, voici ce que j'ai fait:</p>
+<p>Premièrement, vérifier que l'acpi est installé:</p>
+<pre>sudo pacman -S acpi</pre>
+</p>1) créer le fichier /etc/acpi/events/lenovo-mutemic</p>
+<pre>
+event=bouton/f20
+action=/etc/acpi/lenovo-mutemic.sh
+</pre>
+<p>2) créez le fichier /etc/acpi/lenovo-mutemic.sh</p>
+<pre>
+#!/bin/bash
+INPUT_DEVICE=" 'Capture'"
+VOTRE_USERNAME="philip"
+if amixer sget $INPUT_DEVICE,0 | grep '\[on\]' ; then
+    amixer sset $INPUT_DEVICE,0 toggle
+    echo "0 blink" | sudo tee /proc/acpi/ibm/led
+    DISPLAY=":0.0" notify-send -t 1000 -i microphone-sensibilité-muted-symbolic "Mic MUTED"
+else
+    amixer sset $INPUT_DEVICE,0 toggle                       
+    DISPLAY=":0.0" notify-send -t 1000 -i microphone-sensitivity-high-symbolic "Mic ON"
+    echo "0 on" | sudo tee /proc/acpi/ibm/led 
+fi
+</pre>
+<p>3) redémarrer acpi</p>
+<pre>systemctl restart acpid.service</pre>
