81. here could be several reasons for not using DRI As far I know only one graphic card in a system can use DRI The Nvidia closed source driver does not support DRI In case one of this reasons applies to your system you do not need different XFree configuration files for the different displays You can configure your system for Xinerama using the tools provided with your distribution and reading The Xinerama HOWTO so when the system is used by a single user he she could switch to Xinerama desktop and use all available displays for a bigger desktop Once configured for Xinerama only small additions are needed to achieve multiple independent desktops All you have to do is to add new layouts which use single screen definition and have independent input devices well this is actually needed only for the mouse devices as the keyboard is managed through the vt n option If you have configured Xinerama in the following way Section ServerLayout Identifier Simple Layout Screen Screen 2 Screen Screen 1 RightOf Screen 2 InputDevice Mousel CorePointer InputDevice Keyboardl CoreKeyboard EndSection To achieve multiple independent desktops you only have to add layout definitions for a single screen Section ServerLayout Identifier first Xserver Screen Screen 1 InputDevice Mousel CorePointer InputDevice Keyboardl CoreKeyboard EndSection Section ServerLayout Identifier second Xs
