How to start a dialog at startup after login in?

Question

I want to display a dialog at startup after the user log in?

How would you suggest to do automatically launch a dialog at startup?

Example of dialogue:

zenity --question

Answer 1

As this question states, it might depend on what display manager you are running, but you can try to add the zenity command to ~/.xprofile.

I don't really suggest you to add it to ~/.profile as it will try to execute it when you login in a shell (i.e. in terminal) and it will probably fail if it has not a display defined (for instance if it is a remote ssh connection).
