You need to use 'su -m', which leaves the environment, including the DISPLAY export unchanged from the current user, but changes the userid to the user you want to switch to. You can then run your x program as the user you wish to use. I believe this is a MIT-MAGIC-COOKIE issue and is reasonably well documented in the questions mailing list archive. In your previous KDE life, were you using XFree86 v3 and now you have switched to XFree86 v4? This is one of the first things many users run into after they switch.
