How run programs outside X to take effect inside X?

From the command line (what is not on X) how can i run a program to make effect on the X? Example set keyboard layout, or make the colors of the screen reddish, for the script what automatically runs after suspend.

The problem it want to be run from the X because otherwise there is no effect on that and maybe it will need to be run with the user account, but i can do that. That script doesnt run in the graphical user environment, that is the problem.

The program must be run from the same user who is logged in in X. You must set the $DISPLAY environment variable. The value is usually ":0", if there is only one local X session. You can find the correct value by opening a graphical console program in X, and typing

On the out-of-X session:

export DISPLAY=":0"

There are some command line programs for setting the behaviour of X programs. See man Xorg for start.

Or you can edit relevant configuration files of X programs to set them up. You would need some research.
