It pains me that there's still no comprehensive user docs for kernel features. Everything from hybrid graphics to power-saving to cpu frequency scaling keeps changing from kernel to kernel, and you need a PhD in kernel hacking to know how to use any feature of a specific kernel. I've searched forums for weeks trying to gleam enough information to just get a graphics card to work.

I'm still having an issue where double-finger-touchpad-scrolling causes my X server to core dump, and I can't force the X server to actually dump a core file, because I can't run `ulimit` before the X server runs. You're kind of just shit out of luck as a Linux user.
