kubuntu allow remote x application

cptwngr · 03-07-2007, 04:32 PM

I need to be able to set displays back to my local machine and run applications. This seems to be disabled in kubuntu and I can't find where to make the change.

Typical scenario:
Run xhost + on my machine
ssh into a remote machine
export DISPLAY=myipaddy:0.0
start remote app.

GNOME has a config for this in GDM I think but I can't find the equivalent in KDE.

I have changed my ssh_config to allow X11 forwarding.

Any ideas?

You mean start a application remotely and have it appear on the box you ssh in to?
if so then you run

Code:

xhost +

from the target box, then just ssh in and set the display to ":0.0"

If you mean you want to run an application from a remote system, and have it appear on your system, so you control it remotely, then you don't set the display to myip:0.0 or use xhost, you just ssh in with

Code:

ssh -X user@host

the display will automatically be set. Then you can start an app from a remote location, and have to appear on the box you are logged in to.

I don't think that is going to work for me since I have to su into a password less account. I'll keep digging, it has to be something simple, I've been doing this on all kinds of *nix for years.

"I found that I had to configure KDM in Kubuntu to listen on the network to accept connections to run X. Simply setting the DISPLAY variable on the remote system, typing xhost + on the local system and then running the X application on the remote system would not work.

The key file is /etc/kde3/kdm/kdmrc

In there is a line that says:-

ServerArgsLocal=-nolisten tcp

Just comment this out by putting a # in front of the line and restart X by logging out and back in again."

I have Kubuntu 7.04

I want to ssh in from work and launch a graphical app on my home desktop (gaim chat) so that it just sits in the tray (or is on-screen, I don't care) at home. I don't want to forward X11, nor control it remotely, nor see the application. I just want the app running at home on display :0 so that people can leave me a chat message on my home machine.

does this thread address that? Or should I start a new thread?

you should just be able to start the app like this:

Code:

user1@remote:~$ ssh user2@local
user2@local's password:
user2@local:~$ DISPLAY=:0 gaim &
user2@local:~$ logout
Connection to local closed.
user1@remote:~$
