hi, Id like to know how to set up dual head in clone mode with different res, since at the moment the big desktop sucks and using right\left of will disable compiz. in aticonfig --help I read:
--dtop, --desktop-setup=STRING
clone 2 screens - same content, allows for different refresh rates/resolutions

but how to set different res? I tried with --mode2=W1xH1,W2XH2,W3xH3,...
but it didnt work, it doesnt modify my xorg.conf
any idea?
