Launch Application at log on


Hello, my machine runs on linux.

How do i configure it such that as soon as a user logs in, it launches a flight simulator program that i installed.

What i want is as soon as a guest logs in, the flight simulator is launched and thus the guest is not able to access the desktop, only use the simulator. Kind of like a cyber cafe software.

Please help...

The cleanest way I can think of is to define a new gdm/kdm session that only starts your simulator (I suppose it is fullscreen and does not need multiple windows). That way, there's no desktop, no window manager, nothing but the simulator, so there's 0% chance of the user accessing the desktop
Besides, you'll save memory and CPU.

Yves.

HI, What is a new gdm/kdm session and does that mean that my machine will not be able to run other programs when the simulator is in use?

Suppose i wanted an administrator log on to be able to run other programs even go to the desktop. But when a guest logs in, they can only use the simulator.....how would i go about this....thanks in advance.

I'm not on Linux right now, so don't rely too much on the exact paths and filenames I give, but basically, it comes down to this.

I assume you run gdm because I haven't used KDM since ages
And I assume you won't be doing any administrative task under the same login as the simulator login

1/ Create a session script, let's say /usr/local/bin/XsessionSim:
Code:
gnome-screensaver &
/path/to/your/simulator
I just hope that gnome-screensaver's ability to propose swithing back to the login screen is linked to GDM, and not to the gnome desktop.

2/ Create the window manager session. For me, it is in /etc/X11/wmsession.d/; just copy a previous one and adapt it so that it executes /usr/local/bin/XsessionSim. restart X.

3/ On the login screen (GDM), select your simulation user, and change the session to the one you just defined.
For the administrator however, the session will remain what you currently use.

You should be able to switch between users by hitting the screen-saver keys-shortcut, if there's one; if there isn't, just configure xbindkeys and add it as the first line of your session script: "/usr/bin/xbindkeys &" (probably).

If that is not enough, you'd best abandon the minimalist path, and turn instead to an adapted window manager, such as Matchbox.

Yves.

[edit:]Now that I think about it, if you don't care for the screen-saver, you can just go ahead with xbindkeys, and configure it to launch /usr/bin/gdmflexiserver instead of the screensaver; you'd then remove the gnome-screensaver line from your script of course.[/edit]
