There's nothing in /var/log/Xorg.0.log, and X config was attached.

Using strace kills X - there's no output in the logfile, and it's unuseable.

I tried to get a second X running (to run sysprof from there).
But sysprof needs to be compiled - so I need the kernel sources.
I have the sources (custom kernel) - but the module doesn't load ("invalid 
module format").

I have to do some tracking what's wrong.


I now tried to use strace on a second X - but for the other user X didn't 
hang.

Any ideas?


Regards,

Phil
