Comment 1 Dave Jones 2006-07-30 20:25:49 UTC

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
pm-suspend instead.

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
bug.

Comment 2 Wade Mealing 2006-07-30 23:29:39 UTC

Ok, machine responds to capslock.

Comment 3 Dave Jones 2006-07-31 23:30:49 UTC

ok, then it's likely some video reinitialisation magic missing from pm-utils.

Using pm-suspend

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
already ?)

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.

Note:

Each time pm-suspend has been used, I have been able to reproduce:

Comment 7 Wade Mealing 2006-08-04 14:05:30 UTC

And.. now it suspends ! yay!

working in:

Comment 8 Christopher Blizzard 2006-08-04 14:23:07 UTC

But does it unsuspend? :)

Comment 9 Wade Mealing 2006-08-06 23:37:02 UTC

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

Comment 11 Wade Mealing 2006-08-07 07:15:18 UTC

Although... (queue dramatic music),

It seems IRQ #9 gets disabled, which means acpi events no longer work after suspend.

Comment 12 Christopher Blizzard 2006-08-07 12:28:51 UTC

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?

Comment 13 Wade Mealing 2006-08-08 03:16:37 UTC

Yes, will do so now.
