You MUST have "Screen n" keywords in every single device section in
multihead configurations.  Your X server is misconfigured.

There may or may not be additional problems once the X server is
configured properly.  Please correct this and provide a status

Note: our config tools do not properly configure xinerama or other
multihead.  You must configure it manually.
Comment 6 Mike A. Harris 2005-05-10 18:16:41 EDT
The problem reported here is due to X server config file misconfiguration.

While it is true that the X server should not crash even if it is
misconfigured, such a crash is a corner case which is not something that
would work even if the server were fixed to not crash under this
misconfiguration.  As such, the server crash is a low impact bug that
doesn't affect normal supported X server usage.

Please refer to the X server documentation for assistance in configuring
triple head setup, as our tools do not support configuring such setups

Closing bug "NOTABUG".
