Obviously, it's an authorization problem, but I'm not sure where to look. System is Slackware 8.0 with considerable modifications. X is 4.1.0, kernel is 2.4.18 (although I doubt this matters). I have a newly compiled XFree86 4.2.0 ready to go when I sort this out. Any takers? Thanks, Kurt -- Tuesday is the Wednesday of the rest of your life.
