Bonsoir.
Ce sujet m'intéresse, ce script, il fonctionne comment ?
#!/bin/bash
# Automatic fan controller
# Tested on a eee 1005ha running Ubuntu 9.10 Karmic Koala
# Test with 'sudo eeefan background'.
# If works, 'sudo cp eeefan /etc/rc2.d/S99eeefan'
# and reboot.

FAN_SPEED=$(($FAN_SPEED * 250 / 100))
echo $FAN_SPEED > $fan_control
}
# Turn on manual fan control
echo 1 > $fan_manual_switch
# Run eeefanu, then wait 10 seconds.
while [ 1 ]
do
eeefanupdate
sleep 10
done
Si j'ai bien compris il permait de modifié la vitesse du ventillo ?
