Here is my situation. I have an iMac G5 running Tiger. I have an old Dell running Ubuntu Linux. I know that I can use VNC to control the iMac. My question is, my experience with VNC is that it will let me control the desktop. Is it possible to have a completely new login session, so that I can be working remotely, and my wife could be working locally? Thank you!
 
I think the only way to do something like that in VNC would be to have a second X-session running in the background of your linux box. If you have X11 installed on your Mac, then you have other choices. One is to use ssh tunnelling with X11-forwarding, which would allow you to run individual apps from your linux box on your Mac. Another (not so secure way) is to use the remote X capabilities that are built into the X-server. To do this you would need to enable XDMCP on the linux box. Then you can point your X-server to the IP-address of the linux box and it will give you a full graphical login when it connects.

XDMCP is full of holes though, so you want to limit access using your /etc/hosts.deny file, and probably even use an ssh tunnel when you login. I would also not suggest doing this outside of a local network. If you want to know more about XDMCP, then a google search will give you loads of info.

I was going to use an SSH tunnel with RSA key authentication either way I go. If I do X11 forwarding, can I run apps like MS Office?
 
what he suggested was a way to run LINUX application through a tunnel on your Mac, not the other way around. just run open office if you need to work ms documents on your linux box. a x11 session will not all you run ms office if you did it the other way because ms office isn't a x-windows app.
