I’ve got both users logged in under Leopard 10.5.4 with fast user switching, but can’t get it working for the life of me. I’ve tried the advice on the Redstone site. No luck. Anyone have any experience with this?
If you have two users logged in at once, and each session is running a Vine Server (on different ports) then you should be able to establish VNC connections to both of them at once.
Now, you’re running Ubuntu in one of those sessions (under Parallels or Fusion), is that right? So what problems are you having exactly? Please be more specific about what you’re trying to do and what isn’t working.
