Hi Folks,

I have developed a java application that I wish to host on my server for remote clients to connect to via FreeNX.

FreeNX is working well, except that the following line in my java code:

this.setExtendedState(this.getExtendedState() | this.MAXIMIZED_BOTH);

isn't maxmising with java application when I try and run my java app from the NX client.

Now, if I ask my NX client to start GNOME first, then run my program manually with within GNOME, it maximises ok.

My question is:

1) How can I set up GNOME (or KDE, or XFCE) to run a single application once a user logs in? Then ideally, once the user terminates this program, exit the GNOME session..

Thanks

Hi jonnytabpni,

I haven't used Gnome in a while but if i do remember correctly there is a session customizer.

Which means you can turn on applications to start up when you log in.

System -> Preferences -> Sessions

Go to the "Startup Programs" tab, click the Add button and either use Browse to add an application from the /usr/bin directory
or use the Command field and write the programs command in (the one to open it).

You can also add a name and a comment.

After your done, click OK then log out and log back in again.

If you need a bit more ino on how to do it check out this link.

For the second part of terminating and exiting, I can't help you on that one.
Google is your friend.

If I do find anything, I'll post back.

Hope this helps.

If you are only going to run a single application you really don't need kde or gnome. The more complex a desktop is the more complex that it will be to lock it down. If your application is able to handle windowing by itself or doesn't have secondary windows at all then you can even run it without a WM. If not, use a very simple wm that won't provide a menu or a launcher, and that doesn't have any default keybinding to launch a terminal emulator.

However, that doesn't stop the user from logging into a console and launching apps on that display manually, you can always disable VT switching and the c-a-backspace key combo to zap the server in your xorg.conf to cut that as well.

You should also google for something like "linux kiosk" to get some ideas.
