Greetings, list....

Below, please find Xorg log for the recurring error message. This occurs
consistently; with or without loading radeon via rc.conf; and no updates
since early Saturday, February 11, EDT, seem to remedy the situation. It
appears to be related to a bug reported elsewhere, where X or the window
manager fails to start; but I could be wrong.

That said, to where should I post this...-bugs or -x11?

===End error===

This is with my user account, employing windowmaker; with root, XFCE
fails in a similar manner, and on one occasion dumped core. No core
dumps with the user account. Other than this, I have no clue.

Thanks for any help,

Joe
