I want to run a开发者_运维问答 GUI application as soon as x starts up in Ubuntu. I thought upstart might work, so I created a conf file inside /etc/init/ but it seems that it's not working correctly.

myjob.conf

start on startup
task
    exec /home/camino/test/qt/guiapp

Any suggestions?

Oh, ubuntu...

Usually most distributions will let you start Xorg yourself rather than let a login manager do it such as GDM or KDM. If you run startx from the commandline, it will read the ~/.xinitrc and load any window managers or other stuff you put there. But since you have Ubuntu....

To run a script prior to GDM/KDM startup, you could either

1. Write your own Upstart script to run prior to GDM; or
2. Modify your system GDM script to run a custom external script (eg, your /etc/init.d/whereami script) as one of its initial tasks.
3. Run your Xorg-application before GDM/KDM runs, put the script in /etc/init.d/SXYYourScript where XY is lower number than the GDM one.

Also check /etc/gdm/Init/Default maybe is what you want.

I suggest you go with 3 since its more simpler.

But why would you run any Xorg app before the login manager?

Put it after any lines in ~/.xinitrc

You could make a script, myblabla.sh then put that in ~/.xinitrc
