I now have ACPI events for F1 - F12 (after creating some events for them)=

Excellent - that'll come in good use.

I didn't initially, and it also gave me corruption. I wonder if it's=20

It's an on-board Intel 915, so neither of those. Based on a google I=20
started with, I'm using the Knoppix suggestion of vesa, but I'm sure I=20
should be using something else.

sda, caused me all manner of problems during installation :)

That does the same as the lid being closed, but I just figured out=20
something:

If I actually stop mysql first, it actually sleeps. Just implemented a=20
blinking sleep light and all good.

Whoot!

So, now I have sleep, wakeup doesn't properly restore the external USB=20
mouse, but an unplug-plug fixes that. I suspect I need to unload a few=20
more modules, but I'll take advice on that.

It doesn't hibernate just yet, but I feel like I'm making a little=20
progress here.


Any more clue-bats to go around?
