Howto configure /etc/X11/xorg.conf automatically?

[Carlos Lang]

try

$ sudo Xorg :1 -configurewhich produces a xorg.conf.new file.

Then move that file to /etc/X11/xorg.conf.

re: from Xorg man page:
-configure
When this option is specified, the Xorg server loads all video
driver modules, probes for available hardware, and writes out
an initial xorg.conf(5) file based on what was detected. This
option currently has some problems on some platforms, but in
most cases it is a good way to bootstrap the configuration
process. This option is only available when the server is run
as root (i.e, with real-uid 0).
best of luck.
