I have Ubuntu 11.10 installed on a laptop shared by multiple members of our family. When I execute the 'w' or 'who' command from a command line, I only see my account even though there are three users logged in.
The funny thing is, I get different results when the command is executed from each of the different accounts on the machine. When I execute the same command from my kid's account, I see mine and the kids accounts listed. When I execute it from my wife's account, I see all three accounts: her account, my account, and the kids account.
All three accounts are actively logged in, and I'm just switching between accounts and executing the same command. Why the different results? Sorry if this is simple straightforward answer. I searched and couldn't find anything.
Not sure if it matters, but I'm the only administrator on the laptop.
