I tried to use the very new XFRee86-4.0 server, but ran into problems with .rpm dependencies. I eventually gave up and tried to get my system back to its previous state. To my chagrin, it now can no longer run X. I'm using the same XF86Config file as before (I backed it up), and root seems to be able to run X, but when users try, they get
Authentication failed - cannot start X server
Perhaps you do not have console ownership?
How can I fix this?
