What I had im my mind behind "closing the lid" is the fact that closing the lid leads to suspension of the system. What you propose seems a bit drastic to me as it makes the system nearly unusable for many people (that would want network or bluetooth keyboard). Also, you missed the cardreader (controllable via /sys/devices/platform/eeepc :)). If we want to controll the power of all devices that can be controlled, the keyboard would fill with shortcuts. Related, I recently added "options usbcode autosuspend=0" to /etc/modprobe.d/local as suggested by powertop. The bluetooth device is still powered upon activation, though (/sys/devices/usb/4-1/power/level is "on" and should be "auto"). Perhaps this could be corrected in the script. The tricky part is getting the device address. Hardcoding "4-1" seems bad, although tempting, as the device is built-in and should not change its address... But on another model it could be different. *sigh* -- dam JabberID: [EMAIL PROTECTED]
