[debian/illume] Can't suspend

[Jeffrey Ratcliffe]

When I press the power button, I get a group of icons, one of which is
a crescent, which if I press, I get a message saying that it is going
to suspend, but the doesn't.

I'm using the 2.6.28 kernel.

How can I get it to suspend?

Another icon is a padlock. If I press that, the screen is locked, but
I can't get a keyboard up to unlock it.

The close application and shutdown buttons work fine.

Regards

Jeff
