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:

The randr, and xrandr, are used to configure screen resolutions. See these:

so
Code:
Xlib:  extension "RANDR" missing on display "localhost:11.0".
means there is no resolution on the remote machine?

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.

The command is present but I don't know why xmanager doesn't work
Code:
mahmood@orca:~$ xrandr -help
usage: xrandr [options]
  where options are:
  -display <display> or -d <display>
  -help
  -o <normal,inverted,left,right,0,1,2,3>
            or --orientation <normal,inverted,left,right,0,1,2,3>
  -q        or --query
  -s <size>/<width>x<height> or --size <size>/<width>x<height>
  -r <rate> or --rate <rate> or --refresh <rate>
  -v        or --version
  -x        (reflect in x)
  -y        (reflect in y)
  --screen <screen>
  --verbose
  --dryrun
  --nograb
  --prop or --properties
  --fb <width>x<height>
  --fbmm <width>x<height>
  --dpi <dpi>/<output>
  --output <output>
      --auto
      --mode <mode>
      --preferred
      --pos <x>x<y>
      --rate <rate> or --refresh <rate>
      --reflect normal,x,y,xy
      --rotate normal,inverted,left,right
      --left-of <output>
      --right-of <output>
      --above <output>
      --below <output>
      --same-as <output>
      --set <property> <value>
      --scale <x>x<y>
      --transform <a>,<b>,<c>,<d>,<e>,<f>,<g>,<h>,<i>
      --off
      --crtc <crtc>
      --panning <w>x<h>[+<x>+<y>[/<track:w>x<h>+<x>+<y>[/<border:l>/<t>/<r>/<b>]]]
      --gamma <r>:<g>:<b>
      --primary
  --noprimary
  --newmode <name> <clock MHz>
            <hdisp> <hsync-start> <hsync-end> <htotal>
            <vdisp> <vsync-start> <vsync-end> <vtotal>
            [+HSync] [-HSync] [+VSync] [-VSync]
  --rmmode <name>
  --addmode <output> <name>
  --delmode <output> <name>
I don't know is that message related to the host configuration or xmanager settings
