SUSPEND (sleep) command

Is there a command I can run from the command line that would allow my Ubuntu Server box to go on SUSPEND? I'm using Karmic 64bit. I'm trying to set my server to SUSPEND to save power, then WOL when needed. Thanks in advanced.

You should have pm-suspend: see "man" for details. You might also do an "apropos suspend", which might show some other useful stuff: I seem to remember there's a tool to see if suspend will work properly on a system.

Since you want a command-line option, and assuming you want to suspend to RAM, as a test you might try:

Code:

shell$ sudo echo -n "mem" > /sys/power/state

and see if the machine goes to sleep AND if it awakes cleanly. If so, there you go; if it doesn't awake cleanly (or doesn't sleep) you have a little more work ahead of you.

Cheers!
