Screen remains black.
Additional information as it comes. I might try and work this bug..
Nearly every laptop needs some sort of workaround on resume. Echo'ing stuff into
sysfs isn't going to make those workarounds happen. You should be using
If it resumes, but the screen remains off, but for eg capslock toggles the LED,
then it's usually a missing tweak to pm-utils.
If on resume the machine doesn't even respond to capslock however, it's a kernel
Ok, machine responds to capslock.
ok, then it's likely some video reinitialisation magic missing from pm-utils.

the screen goes blank, i see a flashing cursor in the top right.
The light on the front of the macbook pulsates gently (this is sounding graphic
I press the power key, i hear the dvd-rom flick into life, the backlight comes on.
Pressing the caps lock key, no light comes on or off.

But does it unsuspend? :)
Going to suspend..
Suspended (networkmanager didnt auto reconnect to network...)
Resumed.. (I'm typing on it now )
pm-suspend manually.. it suspends and returns
Wait 15 minutes on battery.. it suspends and returns
Although... (queue dramatic music),
It seems IRQ #9 gets disabled, which means acpi events no longer work after suspend.
That would explain a lot. My machine has started suspending and resuming (yay!)
but after it does, a lot of things don't work. Closing the lid won't suspend
the laptop. gnome-power-manager also acts weirdly. One step at a time.
Think we should open a new bug since at least we're returning from a suspend?
Yes, will do so now.
