Hi, I installed the NVIDIA drivers from LIVNA to get my dual-head setup working as the stock xorg nv driver is totally broken when two monitors are connected to the same graphics card. Now I wanted to test the shiny new graphics effects offered by compiz, but I can't get compiz to work at all. It always tells me: compiz: No RandR extension Right now I'm running metacity without any problem. Best regards, Bernd.
