unable to connect remotely
I use Xmanager to connect to a linux machine (ubuntu 10.10). However there is no display. Here is the log:

I am not sure about that. Does the remote machine have a graphical desktop installed and working correctly? Perhaps you could try using xrandr to get a proper graphical desktop from the remote machine.
I am not familiar with using Xmanager.

You should already have
xrandr installed by default. Try running the command, or try reading "man xrandr" to verify that it is indeed installed.
