Ken is pretty much right on, but I'll add my thoughts.

Right when 7.3 was released, I thought about pushing it into BLFS (I
even have the wget/md5sum files basically completed). But, I've been
following xorg a lot closer in recent months, and 7.3 was not the best
release. Input hotplugging landed and brought a ton of new bugs with
it. Also, there's a lot more RandR-1.2 usage in the server and
drivers, which has new, subtle bugs.

The book should definitely wait for xorg-server-1.4.1. 1.4 had a ton
of bug reports and crashers. It's worked pretty much fine for me,

Watch out for the hal/dbus input usage. It's pretty cool when it
works, but there are definitely bugs. You may not want to bother

I think they're pretty much the same. Just pixman is new. Mesa 7.0+ is
just bug fixes, and I believe it's still source compatible with

There's no reason not to use xcb. There was the issue with locking
bugs in binary clients (source ones have probably had the bugs fixed),
but you can work around them with the environment variable. I've never
had to use it, and I doubt you will, either.

pciaccess was actually merged after 7.3, so the 7.3 drivers won't need
it. If you jump to xf86-video-intel-2.2.x, then you'll probably need

Between the input hotplugging and the extended input devices work that
got in, a bunch of input drivers broke. Evdev is a generic input
device for Linux (meaning it handles keyboards, mice, joysticks,
etc.), and xf86-input-evdev is just a layer over it.
It's the only driver that works correctly with input hotplugging,
which is why they were saying it's required. However, if you don't use
that, then any of the drivers should be fine. Evdev is pretty nice for
"just working", anyway. If you have a mouse with a lot of buttons, I'd
say give it a go as it usually works right out of the box.

It's a predecessor to 1.4.1, and I'm pretty sure the slowness is just
due to the high amount of bugs introduced. 1.5 will be the server for
