Some distributions automatically load the
~/.Xmodmap when a user logs on in X - if yours does,
consider yourself happy. One of the distris which doesn't do it is Gentoo,
while SuSE does.
Here is how you get it loaded automatically: You've got to open
$KDEDIR/share/config/kdm/Xsession
and insert the following code at the beginning of the file (but after the shebang #!/bin/sh):
if [ -f $HOME/.Xmodmap ]; then
/usr/bin/xmodmap $HOME/.Xmodmap
fiNow save, logout and log in again. Your modmap should have been loaded now.
Xorg (at least in version 7.0) has an xinit script at
/etc/X11/xinit/xinitrc that loads a global
Xmodmap file for all users. The default location is
/etc/X11/Xmodmap. Since KDE doesn't automatically
do this, you should add it: Open the Xsession file (as described above)
and add the following line:
[ -f /etc/X11/Xmodmap ] && xmodmap /etc/X11/Xmodmap
