The Challenge In Delivering Open Source GPU Drivers
yuhong writes "After the recent Intel Sandy Bridge launch left Linux users having to build the latest source from Git repositories in order to have full support for the integrated graphics, Phoronix looked at the problems involved in delivering new graphics drivers for Linux."
They did release drivers for the latest kernel, and they work great. However, you do need bleeding edge versions of the entire graphics stack to use them. This is a problem when combined with non-free ATI and Nvidia which always lags behind with no way for maintainers to get them up to speed.
In other words, a distro can include "old" kernels/drivers/X-servers with non-free ATI/Nvidia support XOR newer and less tested ones with the latest Intel support.
Either way, it's a reduced user experience and that's what TFA is on about.
