Hi there: I tested the Fedora 13 TC live images for Gnome and KDE with mesa-dri-drivers-experimental on an Nvidia Quadro NVS140M (http://www.smolts.org/client/show/pub_f6255243-d01d-4bd3-b9bc-50356f57ff9c). KMS works nicely, glxinfo confirms dri with nouveau/gallium. With the Gnome spin, desktop effects (shadows, cube, wobbling) work flawlessly. With the KDE spin, desktop effects (OpenGL) can't be enabled unless forced (disable feature detection), and then X hangs. I know what "experimental" means, but I'm wondering if others experience the same or that should be reported. Michael
