Bug Description
I'm running gutsy tribe-4 on an Intel CHGL30945PM1 laptop. Hibernation works as expected. However, sleep doesn't.
When selecting sleep from the System->Quit menu, the machine goes asleep and the power led blinks indicating that the laptop is sleeping. When pressing on the power button, the machine wakes up but the screen remains black. Even when switching to the other terminals with Ctrl-Alt-F*, the screen remains black.
