Hi, everyone<br><br>I'm working on accessibility and disabling the touchpad is necessary for kids who can't control their movements<br>and need other input devices.<br><br>I played a little bit around /sys/class/... and /sys/devices/... and found that with this command:<br>
<br>echo 0 > /sys/devices/platform/i8042/serio1/pwred<br><br>you get "echo: write error: Operation not permitted", but still the touchpad is disabled. Keyboard still works and<br>I can plug a regular usb mouse. The thing is I can't reactivate it until I reboot the XO.<br>
<br>I just wanted to know if this behaviour is normal or it's a bug and I'm not supposed to be able to disable the touchpad.<br>If that's the case, is there a neater way to do that?<br><br>Thanks,<br>Emiliano<br>
