Cedric.
Hi. Thanks very much! I have installed the module and dock applet. Seems
to be working -- although I'm worried about frying my laptop!
How do I check the current speed setting of my processor? I've tried to
throttle it down even under a/c because of the noise of the fan.
I'll report back with syslog notices soon.
Kind regards,
Rory
