Does the power button work properly on Ubuntu? And if so is there a patch I can apply to the vanilla kernel to get the power button to work? We are trying to deploy this as a "plug and play" server. They plug it in, it turns off. When they are done they hit a single button and wait for the power light to turn off.
I would prefer not to have to buy a usb panic button that triggers a shutdown, while it would be funny it would give the wrong impression to the user.
UPDATE: It seems the power button kind of works. It does not trigger at all in console mode (which is should), but if I am logged in to X-Windows pushing the power button twice will bring up the "shutdown your computer?" dialog. So it seems to "mostly work", just not as a standalone way to shut down the computer.
