You are right. The script was running from clicking a python wx button, the issue I've just figured out is there is another command needs be run before it as following script.

exec su -l ${user}
killall gnome-panel

The "exec su -l ${user}" refreshed the change of user access permission, but lets user to log into another environment where the following "killall gnome-panel" won't afffect to the current parent environment which called script.

$ update_user_id.sh

In update_user_id.sh:

exec su -l ${user}
killall gnome-panel


The question is really, whether it is possible to make the subsequent login and changes to affect to parent environment? Or there is no way to make it work?

Thank you.

Kind regards.

$ update_user_id.sh


In update_user_id.sh:


exec su -l ${user}
killall gnome-panel

NAME

       gnome-panel-screenshot - GNOME screenshot utility

SYNOPSIS

       gnome-panel-screenshot [--window] [--delay=int]

DESCRIPTION

       gnome-panel-screenshot  is  the command-line interface version of the gnome-panel screenshot option. The gnome-panel screenshot option cap-
       tures the complete screen without the delay option. The command-line option is more versatile; it allows you to capture the screen image of
       a window, as well as the complete screen. gnome-panel-screenshot also allows you to specify a delay before the screen or window is captured
       into file.

       If the --window option is used, you must move the mouse pointer to the window to be captured. The --delay option is always  used  with  the
       --window  option,  to allow sufficient delay to set up the required screenshot. Once you have captured the window region, you are presented
       with a preview of the snapshot. You can then choose one of the following three options to handle the captured image:

	 o  Save screenshot to file

	 o  Save screenshot to desktop

	 o  Save screenshot to web page (save in ~/public html)

OPTIONS

       The following options are supported:

       --window        Capture a screenshot of the window in which the mouse pointer is located.

       --delay=int	       Pause for int seconds before capturing the window or screen

EXAMPLES

       Example 1: Capturing the full screen

       example% gnome-panel-screenshot

       0	Application exited successfully
