CentOS - Jul 2007 - "driconf" to try to solve "texture size" problem with beryl+radeon+dualhead+mergefb

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

=== 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
beryl/compiz?

Distro:
   Centos 5 (kernel 2.6.18)
   Xorg 7.1.1
   driconf 0.9.1

Are you trying to span your display across the laptops LCD and the  
external one? If so, does your final total resolution happen to be  
2960x1050?

It looks like that's where the issue is, however I haven't played with  
beryl in quite some time now...

I have a Radeon X600.

I don't stand fine how I can change that "things" you said. Could
you
explain a bit how can I change that parameters? What configuration files /
programs must I change/run? How?

As I said, I have no knowledge about Xorg graphics architecture or any
graphics related parameters.

I can change any xorg parameter, or any configuration file using your help
(or any link that anybody post here). But I think, at this point, my
xorg.conf is well configured (thanks to the xorg buys for their help) and
must be any other configuration file or perhaps I must think in wait for a
new beryl release or a new driver release. I don't know yet.

Thanks

Conclusion:
   1) I only can use beryl (with this videocard) in a resolution less than
2048x2048 (adding the 2 screens resolution).
   2) In the future, perhaps beryl do the trick.

Thank you very much your answer!!! (you have a beer here!!!).

As some guys apoint to me, I have to restrict to the maximun texture size
my desktop size to allow beryl work with dualhead.

Ok. I do it and ??its working!!

My trick has been to use the second monitor "below" or
"above" the
primary, then my desktop fit into texture size window.

Now I'm happy and can enjoy beryl with a dual head configuration with my
desktop.

Thank you very much to all people that allow me to do that with their help.

In some days/weeks I'll write this into beryl wiki to share my experience
with the comunity.

Thank you very much again.
