Remote access returns error: "X: user not authorized to run the X server, ab

[abcuser]

Hi,
on desktop computer I have Ubuntu 8.04 configured as headless server. On laptop I have Ubuntu 8.04.

Desktop is by default running without "X server". If I need graphics I start it by command "startx". X-server starts successfully without any error.

But if I try to do the same using remote laptop:
1. ssh -X userid@ip_of_desktop
2. startx
and second command returns error:

X: user not authorized to run the X server, aborting.
xinit:  Server error.

I can't quite understand if running commands within desktop using the same password as from remote laptop why I am not authorized to startx?

But if I start X on local desktop I can execute any graphic application on remote laptop (e.g. firefox).

The only problem is I can't start-up X-server remotely.

Directory .Xauthority on desktop has my userid privileges (read/write)

Regards,
Abcuser

Hi,
I figured out. On laptop I just executed firefox command without executing startx and Firefox starts on remote computer. I don't understand this but it is working.

I would like to understand. Can you please provide info to the following question: When "ssh -X userid@ip_remote_server" is executed where is X-server started?
1. On my laptop
2. On remote desktop computer

If now I understand correctly, X-server is started on my laptop? Is it?
Thanks

what are the permissions of ~/.Xauthority on the server ?

ls -a to show them.

Try deleting this file and try forwarding x applications.

Generally it is best to forward single applications rather then the entire desktop. If you wish to forward the entire desktop use either a new x session of Xephyr.
