What you're describing sounds suspiciously like Mac OS X. It's based on FreeBSD and the Mach microkernel, and it has a GUI that is drawn through OpenGL on supported hardware (Quartz Extreme). Also, the guts of the OS are open-source (Darwin), but the GUI (Aqua) is closed. And, Apple just released their own version of X11 which hardware accelerates it through Quartz, and does some of the window drawing with the Quartz engine. And a couple of months back, someone released GTK+ libraries for Quartz which enable Linux applications to be ported over to the Quartz window manager easily.Lord MJ wrote:Well for an OpenGL front end. Some commercial company can take the from what I hear, near perfect, FreeBSD 5 kernel, and develop an OpenGL front end to it, and release it commercially. WIth the kernel remaining open source, but with the front end being a commercial product (with adequate documentation of the api for developers) they could even engineer it so that X apps could be emulated in the new graphics scheme.
Such an operating system would kill Windows in the desktop market if not for the fact that windows is already deeply entrenched, and lots of marketing capital would be needed, plus OEM agreements.
So, basically, someone's already done it And it's not exactly killing Windows on the desktop, although if someone was going to do it, it would be Apple.
