xprofile

An xprofile file, ~/.xprofile and /etc/xprofile, allows you to execute commands at the beginning of the X user session - before the window manager is started.

The xprofile file is similar in style to xinitrc.

Compatibility

The xprofile files are natively sourced by the following display managers:

GDM - /etc/gdm/Xsession
LightDM - /etc/lightdm/Xsession
LXDM - /etc/lxdm/Xsession
SDDM - /usr/share/sddm/scripts/Xsession

Sourcing xprofile from a session started with xinit

It is possible to source xprofile from a session started with one of the following programs:

startx
xinit
XDM
Any other Display manager which uses ~/.xsession or ~/.xinitrc

All of these execute, directly or indirectly, ~/.xinitrc or /etc/X11/xinit/xinitrc if it does not exist. That is why xprofile has to be sourced from these files.

~/.xinitrc and /etc/X11/xinit/xinitrc

#!/bin/sh

# Make sure this is before the 'exec' command or it won't be sourced.
[ -f /etc/xprofile ] && . /etc/xprofile
[ -f ~/.xprofile ] && . ~/.xprofile

...

Configuration

Firstly, create the file ~/.xprofile if it does not exist already. Then, simply add the commands for the programs you wish to start with the session. See below:

~/.xprofile
