hello roman,

what i have to propose is not necessarily a solution, but simply another
step in your troubleshooting.  from what i understand, xorg can usually
automatically detect hardware and make a working configuration.  all you
have to do is move (remove or rename) xorg.conf.  when xorg doesn't find
that file, the automatic detection takes over.  if you're lucky and x comes
up with the setting you want, you know that there was likely a problem with
your xorg.conf.

whatever happens, /var/log/Xorg.0.log should have some pretty detailed
analysis, given the various autodetection tests.  it may help you to work
backwards to try find the problem (or not even bother, if it works!  :)

as i say, this is only another step and most likely not a solution.
hopefully someone else will chime in with a more helpful suggestion.


good luck,
epi
