If a developer was still interested in developing video code, he or she could always look to the kernel for something to do. The X server for the frame buffer is already available as Xfree86-FBDev and has shipped with some distributions. Disadvantages of the Frame-Buffer Driver One of the largest downsides of the new kernel driver system, and the one that has been getting the most attention, is the question of stability. The answer is simply no. It is my opinion that Linux developers reach a higher standard than some other software developers do.
People accept that risk daily.
The new driver system has less supported hardware than its legacy counterpart. In contrast to XFree and to a lesser extent SVGAlib, that is an order of magnitude less support. The video subsystem today is a lot like the sound subsystem was yesterday, i.e., it supports very few cards. With time and patience, developers will no doubt make this new system as robust as possible. Lack of Acceleration Also, the frame buffer is not meant to be a generic base for an acceleration architecture.
