Bug#658778: Suspend from X session hangs Asus laptop.

Thanks for the quick reply, Jonathan.

Not really (the machine is new). I tried older debian 5.09 and 6.03 live cds. 
With 6.03 suspending from a session worked under some conditions (lid) but not 
all (menu).

This doesn't work.

Thanks for the pointer! For some reason I didn't find it while searching 
around (we beginners don't know to search for "pm-" instead of "suspend"). 
Maybe a link could be added on the debian wiki at 
http://wiki.debian.org/Suspend ? The "shutdown" method described in the 
document seems to work. But it is a bit clunky and it wasn't immediately 
obvious how to set this option permanently or whether it even applies to 
suspend to RAM (more for the wiki...)

In the meantime I found the following site 

http://thecodecentral.com/2011/01/18/fix-ubuntu-10-10-suspendhibernate-not-
working-bug

and shamelessly copy-pasted the suggested script. It works pretty well - the 
only obvious problem at the moment is that waking from sleep requires a press 
of the power button (lid-opening doesn't suffice). But at least there is no 
freeze with data loss and reboot. Huge progress.

The working "shutdown" method suggests a bios issue and the copied script 
indicates a usb problem. Follow up might therefore look at the usb settings in 
the bios and investigate a bios upgrade (the changelog mumbles something about 
usb).

The comments on the web site suggest that the solution has helped a lot of 
people and with different machines.

Thanks and best wishes,

Boris
