Unexpected Results from who and w

[rwilkerson]

Just out of curiosity the other day, I ran "w" from my terminal. I was surprised to see that, even though there was someone else logged in (with user switching turned on) only my login was registered. I went on to discover that only my terminal session was registering. My actual login to the GUI isn't picked up by the command at all. I figured this out by running the command in GeekTool. If I had a terminal open, users showed up. If not (even though I was still logged in, of course), no users appeared in the list.

Is this expected? Is there any way, from the terminal, to see all of the users that are *really* logged in?

Thanks.
