+1 to this The nvidia blobs do work well as long as you use them the way they were intended to be used. The way they were intended to be used is the same way Windows uses them, the Linux and Windows drivers share the bulk of the internal code and Linux feature set most definitely is not the driving force here :-) Which means some awesome things the X server can do simply do not work with the blob. The blob also rips out most of the OpenGL and framebuffer code and replaces it with it's own mysterious black magic, this can add more wrinkles. And finally, the Nvidia blob is not at all integrated with the kernel in any meaningful way, so your running kernel usually ends up 2-4 versions behind current. -- Alan McKinnon [email protected]
