"driconf" to try to solve "texture size" problem with beryl+radeon+dualhead+mergefb (ANSWERED)

[ArcosCom Linux User]

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!!!).

Regards
