(I assume you mean OpenGL software rendering) I don't think this is possible with the current scheme, we simply need to disable the DRI if the virtual resolution exceeds 2048 in either dimension. -- Earthling Michel Dänzer \ Debian (powerpc), XFree86 and DRI developer Software libre enthusiast \ http://svcs.affero.net/rm.php?r=daenzer ------------------------------------------------------- This SF.net email is sponsored by Dice.com.
