How to autorun a X program?

[Basudeb]

I am remastering 6.7.1 Live CD. Which file(s) I have to modify so that my application ( wxGTK application) runs after booting. I can now boot up the remastered iso and run the application manually from Terminal in su mode.

I have checked all available links on the net including the Remaster document, using which I am anyway doing the remastering. So, please give me a specific answer ( I am waiting for 4 months) just to get this simple answer from other forums.

I suppose that you use the LXDE.

You could create the directory /home/knoppix/.config/autostart if it does not exist. The next step would be to create a .desktop file for your application, e. g. /home/knoppix/.config/autostart/mywxGTKApp.desktop. Since you like to run that program as root, you could try out the following

[Desktop Entry]
Name=mywxGTKApp
Type=Application
Exec=sudo /usr/local/bin/mywxGTKApp
Terminal=false

You can use your favourite text editor to create such .desktop file. You can read more about .desktop files on the page Desktop Enty Specification.

Of course there are other places (directories) where you could put a shell script that runs your application, but the way described above would ensure that the desktop environment is already up and running.

A stupid question by me:
Do I make this addition in myremasterfolder/source/KNOPPIX/home/knoppix/.config/autostart folder?
Or should I do a chroot and then make the changes?

You don't have to use the chroot environment if you can find the right folder. The .desktop file should be owned by the user knoppix. You can use the chown command to change user an group if necessary.

Thanks, and it worked like a charm.
I am not sure why I have to really scour the sea bed for pearls. Shouldn't all these be in a nice little book that contains all that the Gurus said?
Thanks again, it ends my six month's odyssey. I will have to start trimming and slimming my live CD now.
