Gak. Okay, I now have a clearer understanding of what's going on.
There is in fact a "suspend" item in the menu. When I use that, I get the same result as "sudo pm-suspend": - Screen blanks - All fans keep running - Monitor does not go into power-save mode - Nothing will "wake" the computer - Scroll/Caps/Num lock keys have no effect on keyboard LEDs; Num Lock light is stuck on, others stay off
So I have to power down the PC (i.e. hold down the power button several seconds).
Another detail: I have VMware Workstation Tech Preview March 2012 installed. Maybe that's interfering with sleeping. I don't think I tried Suspend before installing VMware, but I don't remember.
I still think they should have called it "Sleep" instead of "Suspend".

I installed Ubuntu 12.04 on my desktop PC, and I've found that I only have the option to hibernate or power off, and not sleep! Is this normal?
I think it's supposed to be the other way around. The discussion is at https://bugs.launchpad.net/ubuntu/+source/policykit-desktop- privileges/+bug/812394
(I use Kubuntu 12.04, and get all of the options. Hibernate fails about a third of the time on my HP 8440p, and isn't noticably faster than booting from scratch.) _______________________________________________ Roundtable mailing list Roundtable@muug.mb.ca http://www.muug.mb.ca/mailman/listinfo/roundtable
