As some e-mails ago, I'm trying to play beryl in my laptop.

I successfully configured my xorg.conf (thanks to the comunity for the
help that allowed me that).

The problem:

When I boot the laptop without external LCD/CRT, beryl is working fine,
but when I boot it with the external, it recognice fine the external LCD
and don't want to allow beryl run.

What beryl says:

=== BEGIN ===
$ beryl --test-only
* Beryl system compatiblity check                            *

=== END ===

Searching the web I readed that with "driconf" util I can try to solve the
problem. I had installed driconf 0.9.1 successfully, but I don't know how
to change that parameters.

Does anyone used driconf or knows how can I solve this problem with

   Centos 5 (kernel 2.6.18)
   Xorg 7.1.1
   driconf 0.9.1
