SO HOW TO START REMOTE SYSTEM GNOME OR KDE IN MY LINUX BOX


I HAVE ONE ERROR WHILE SSH

what does mean this ..



some times the xserver starting in the remote linux box???


when i give "starkde " the kde starting in the remote linux box.



so how to get remote Desktop please..

Here is a howto that might help.
http://www.ibiblio.org/mdw/HOWTO/Remote-X-Apps.html

Does it work to run a application rather then running an entire session through SSH. In other words, with Xwindows running on the remote host. And running Xwindows on the local machine, just run the programs that you want to do through the tunnel.

If you can't do this, try the -X option to the ssh command. This will enable X11 forwarding for the session.
Also, the :6 in your command doesn't look right. SSH uses :10 I believe on one end and :0 on the other.

As an experiment, log in using SSH and check the value of the DISPLAY variable.
echo $DISPLAY

Then try:
xinit -- `$DISPLAY`

= = = = =

I tried a little experiment myself. I went to vt/2 and logged in as root. I was logged into KDE as a normal user on vt/7. I typed in 'xinit -- :1' and it failed. It gave a message about an invalid '-n' option to xvt. So instead I type in: 'xinit /usr/X11R6/bin/rxvt -- :1'
This almost worked but there was a message about rxvt not supporting UTF8 encoding.

So I tried 'xinit /usr/X11R6/bin/xterm -- :1'.
This brought up X-windows on vt/8. I then entered the window manager in xterm to start a session.

You could try:
ssh -X 10.255.240.103
xinit /usr/bin/startkde-- $(DISPLAY)

You might need to manually enter the value of DISPLAY.
When I tried
DISPLAY=':1.0'
xinit /usr/bin/startkde-- $(DISPLAY)
and
xinit /usr/bin/startkde-- `$DISPLAY`
Both attempts failed with a message about display :0 begin in use.
However
xinit /usr/bin/startkde-- :1
was successful.

sir i have to run my linux box KDE and remote computer GNOME in my linux box.

i mean KDE from my mandrake10.0.


GNOME from remote computer say redhat or fedora or whatever.


thanks..

xinit /usr/bin/startgnome -- :1

no sir normal user can not start a kde or gnome.

ansd i login to root

and #startx -- :2

kde openning in the remote system but not in my system.

It is possible for a normal user to start kde. You can use /usr/sbin/startkde. I just run from vt/2: xinit /usr/bin/startkde -- :1 and it was successful. You need to have the X running locally to be able to receive X-windows messages and have them displayed.

Firstly, try logging into an ssh session on the remote machine as a normal user. Look at the value of the DISPLAY environment variable. When using ssh, it sets this value. I think the value will be :10 but I'm not certain.
echo $DISPLAY

Suppose that the result is
:10

Then try the command in the ssh shell
xinit /usr/bin/startkde -- :10

Now on your local end, I think you want
xinit /usr/X11R6/bin/xterm -- :1
This will start xwindows with xterm on your local machine, and hopefully the x-windows signals will travel through the ssh tunnel.

This link may help you set things up:
Protecting Your Xwindows Session Using ssh-agent

To start a remote KDE session on your local linux box:

On the local machine type:

xinit -- :1

This will start a second X server locally that will be empty and ready to receive the full KDE desktop.

export DISPLAY=localhost:1

This will set the current display to the new (blank) X server

ssh -X user@remote

This will connect you to the remote machine and enable X forwarding

On the remote machine type:

echo $DISPLAY

should display :10 -- if not, then X forwarding over ssh is not set up.

startkde (or "gnome-session" for gnome)

This will start the KDE desktop and display it on the local machine.

Note: Do Not Execute "xinit" on the remote machine!

Note 2: You may need to press control-alt-F8 to see the KDE desktop.

You can also try logging in to single-user mode, then run "kdm" at the prompt. KDM has the option to do a remote login (usually hit Alt+R at the login screen.)

It'll ask you for the remote hostname, and should connect you properly.
