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!!!).

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?

Well as said it's not possible to increase the max announced texture size beyond 2048. You've got a r300-based chip, so you don't have the allow large texture option in driconf, this is r100/r200 only as r300 always announces the maximum.

...

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.

There is nothing you can do. At least your chip shouldn't suffer from the 3d coordinate limit, maybe a future beryl release will do the trick.

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: Checking maximum texture size : failed

Root window size (2960/1050) is bigger then maximum texture size (2048x2048) 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?

Radeons have a texture size limit of 2048x2048 (well pre-r500 radeons), so there is not much you can do. The driconf setting you're refering to was to allow larger textures which might not fit into video memory under some circumstances, but this is the default now and it won't allow larger than 2048x2048 anyway (btw software mesa may have the same limit, but obviously this is not really set in stone). compiz/beryl may work around this by breaking the too large textures up into smaller ones, though I'm not sure if there's work going on in that direction. It won't be very efficient, neither. If you have a pre-r300 radeon, you would hit the 3d coordinate limit too (2048 too), which would need to be solved at the driver level.
