From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Proprietary nvidia driver consists of (at least until recently) from two parts - closed userspace part and open kernel part. Those parts talk to each other with some protocol they change every once in a while and the only combination they support is that kernel module and userspace part must be of the same version. When they mismatch you still get video, you don't get acceleration. And reboot fixes the problem.
AKA bad engineering.
