hi all, thanks to both, archived and close to "real-time" help from  
the users of this list i've got DRI working on my T41 with the 7500  
radeon little card.

since a week im trying to fine tune my server layout to control my  
external monitor 19" sony multiscan CRT.

i have managed to get the layout i want. withouth a clone desktop  
from the LCD but 2 independent spaces. perfect for presentations.

but when i copy paste the server layout from one xorg to the other i  
loose DRI and get the message of DRI disabled -- Dual Head  
Configuration is not working with DRI at present. Please use the  
radeon MergeFB option if you want Dual-head with DRI

below is my xorg.conf, i hope is all a question of bad  
synthax...though i tryied using MergeFB "True"  or "true" or  
"on"...DRI works fine in other configs that dont involve 2  
screens...i get 1200fps under my own glxgears realms.

as always your help is very much appreciated.
