I use the acpi support under /etc/acpi/events and /etc/acpi/actions

The sleep.sh file I now use is here.If you want something to happen
after awaking from suspend mode, it should be easy to see where to put
it in.
Ok. I will admint that I am confused. The script below certainly puts
the machine in suspend to memory mode. But I am at a loss how to wake
the machine up. I am mising something her and I need clarification. If I
use the power button to wake the machine up the machine wakes up but is
quickly frozen. That is what one does in Windows but it does not work
here. How is the wake up done?

I do not have any luck with the "hibernate" rpm or the
"gnome-power-manager" rpms, but the basic acpi method does work here.

Hi,

how to run my own script when starting from "hibernate" mode? (I need to
restart squid and correct centrino-voltages and fan speeds).

rc.local is called on "regular starting" only, right?

Thanks, pf

You may want to take a look at /etc/sysconfig/suspend and the
/etc/sysconfig/suspend-scripts directory tree...


No similar files on my system :(

Neither here.

BTW, is pm-hibernate the right command to suspend-to-disk? Why is there no
hibernate entry in the GNOME menus?
