X11, Window Managers Have you ever been annoyed by Linux' lack of a coherent graphical boot process? Graphics hardware causing problems during sleep/wake cycles? Problematic virtual terminal switches? Kernel-based mode-setting, a new feature of Xorg still in heavy development aims to solve many of these problems by moving the mode-setting code from the user-space X driver into the Linux kernel. Phoronix takes a look at this new feature.

X is *cough* rotten *cough*.

No. Hibernation *does* work in Linux. I'll prove it right now by hibernating my laptop and restarting it. There. See? It worked! What you are forgetting is the huge volume of disparate, broken hardware out there that has been "fixed" by the manufacturer with a Windows driver update. That's what makes hibernation so difficult to solve in a general way. Confining low level control of the video hardware to user space, while depending upon the kernel to do the hibernate/wake up is a recipe for unreliability across the broad range of commodity hardware available.

I would not trade X for any other display system available. And I continue to be puzzled by the tendency of some to unjustly criticize it at every opportunity. What's rotten, and has been for a long time, is the fact that, for whatever reason, control of the basic state of the display hardware has been shunned by the kernel devs.

Don't get me wrong. The complex stuff belongs in user space. But responsibility for something so basic as setting the graphics mode lies squarely within the domain of the OS kernel.

We've been talking about something like this for at least 11 years. Linus rejected the original GGI out of hand back in 1997 or so. And here we are just getting this functionality which has been so sorely lacking for so long. And the delay was certainly no fault of X's.
