xterm xt cannot open display

You have to run this command (xterm) in Graphical Mode (KDE, GNMOE) Try connectig using VNC or console. Alternatively you can set up a X windows server on you computer so the graphics can be displayed on your computer. I am using xming for X Windows server http://sourceforge.net/projects/xming/

An easier way to run this will be to login from other linux box using xterm. On remote machine type
export DISPLAY=<yourIP address>:0.0
On your box type:
xhost +
Then try running xterm on remote box.

I have logged in to linux using putty and have tried exporting the display variable to  <windows ip>:0.0
If i run xhost + or xclock. .. am  still getting the same error.

On windows you have to install Xming and run Start -> Programs -> Xming -> XLaunch

Here is a link for Xming  XWindows displayhttp://sourceforge.net/projects/xming/
If you are connecting from linux box you can just type xhost+ instaed of installing Xming as XWindows is a standard thing on linux.

Hi,
did you export your display
set "your_ip"
then
xclock &

ok sorry you did
ok  change the number for display
export "ipnumber":0.10

Is there any other option other than installing Xming.. as the site is blocked here and am unable to install xming... I have xmanager installed in my system... but connecting through xmanager to linux give XDMCP connection failed.

When trying to connect to linux using xterm through GNOME am getting this error:
** (gnome-session:9815): WARNING **: Missing argument for --display

please help

With Xmanager you can start Xstart and run it with ssh ,telnet etc. See picture. You don't xterm.
If you want run xterm after this from any computer,  do next :
export DISPLAY="your IP:0"
or setenv DISPLAY "your IP:0".

enabling X11 in putty has solved the problem.
