Lagging as usual (almost 2 revisions behind), the proprietary NVIDIA display driver is broken with the current Linux kernel. If you want to get it running, you can use this patched driver:
(this is just the kernel module, you must install the 169.12 gl libraries along)
To compile, just run make module-install. For the curious, you can take a look at the diff.
I really hope we’ll get a shiny free and open source NVIDIA driver soon instead of this ugly blob.
