Like Jon said the hardware can do it but the XFree86 driver doesn't allow it. AFAIK it doesn't even allow XAA acceleration on the secondary head. I can run multiple 3D apps simultaneosly on both heads of my G400 with DirectFB. But currently DirectFB's multihead capabilities are limited so it only works with a TV as the secondary display. -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
