Of course international user > should > restore their national fonts. do you have idea how does xdm/kdm stops the X servers ? and could you give a try to bruby Xserver menu ( you'll find a link in the how-to and on the contrib page) i have to update the Xserver menu page a bit, i found out that kdm do not use [kde-prefix]/share/config/kdm/Xservers & it doesn't use it's own /var/run/*.pid but the one from xdm, so if you want to test it with kdm modify the line in restartDM.sh. and under xdm/kdm the by reseting the display manager to activate the changes does not end the current session on the X from which the bruby_X was called (need to test it a bit: when, why, how xdm/kdm restart the X servers) > I have troubles with my bunch of Nvidia.
