Crashed server log
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.
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
