Hi, thanks for your replies.

There is an update: I have found that if I issue "acpiconf -s 3" from
the KDE Konsole (rather than the VGA console), the laptop goes to
sleep correctly AND it even wakes up. Unfortunately, when it wakes up,
all window decorations and fonts are corrupt (desktop background and
icons are OK). Killing kdm-bin and X and then restarting them does not
fix the problem.

What I find strange, is that KDE seems to make part of the resume
process work, while the computer hangs if the suspend/resume is
handled only from the VGA console.

I can testify that this laptop used to suspend/resume flawlessly under
Kubuntu. That and the lack of errors when compiling acpidump's output
lead me to think that the problem might not lie in Acer's ACPI bytecode.

I'll post my experiments and findings, but at the kernel level I think
there's not much I can strip away because it's already very bare-bones
now.


Bye,
Andrew
