All, I've spent some time and googled for as much time and I can't seem to get the desktop-effects to work smoothly on my laptop. I have a Toshiba Tecra A6 and according to the Xorg log file, here's the information about my video adaptor: (II) NVIDIA(0): NVIDIA GPU Quadro NVS 110M (G72GL) at PCI:1:0:0 (GPU-0) (--) NVIDIA(0): Memory: 262144 kBytes (--) NVIDIA(0): VideoBIOS: 05.72.22.54.17 (II) NVIDIA(0): Detected PCI Express Link width: 16X I'm using Fedora 7 with the latest updates and the Nvidia 100.14.11 driver. Whenever I use desktop-effects and the CPU / hard drive are under load, the mouse gets jerky and intermittently unresponsive. Does anyone have any suggestions? Thanks, Brian
