Essentially, .xinitrc is only used by the startx script, which invokes
xinit. It's not used by any of the typical X display managers (xdm, kdm,
gdm, etc.). They typically have a different set of startup scripts they
use. In the case of xdm, there are system-wide startup, session and reset
scripts, which are specified in a resource file (typically, these are called
Xstartup, Xsession, and Xreset, and the resource file is xdm-config, all
located in the same system-wide directory). The startup and reset scripts
are always run as root, and are used (as their names suggest) to do special
tasks before and after the session is run. Furthermore, the Xsession file
(which is run as the logged-in user) will typically look for and exec a
user-specific ~/.xsession file.
If what you're doing in your .xinitrc file is fairly generic, you can
probably link it to .xsession as well, to use the one script for both
environments (startx/xinit and xdm/kdm/whatever). Of course, you'll want to
look at the system-wide session script for your display manager, to make
sure it does look for a user-specific script, and if so, which one.
