The gentoo thread (from last year) which I was reading suggested that
startx, but also DEs (depending on the driver, intel was ok,
modesetting was not) were broken at that time.

But apparently some people have been using recent versions of the
book on desktops without this problem.
Yes, I'm one of those people. :-) I believe the above might be outdated.
I am using an older ATI card (I don't game, so $25-30 bargain buy for
all of mine, though I just realized that I still have the kernel
parameter amdgpu.si_support=1, though I now forget exactly why it was
put in there):
07:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series]
Having never experienced the issue, I am not fully versed in the topic,
but in X log I have (forgive the root prompt, I'm currently chrooted):
root@lfsdt1 [ /sources/temp ]# grep modesetting /var/log/Xorg.0.log

This is from RL3 with a newly created user who has no group membership
and no suid X binary (I do have the suid wrapper). I just can't figure
out what is different for me. Bruce's proposed build order (elsewhere in
the thread) looks a lot more similar to mine than his previous ones, but
even looking at his previous build order, I couldn't see anything (after
fixing my previous elogind dependency for xtrans). I mean, we've been
building without suid binary on systemd for some time, and never had
issues AFAIK. So for the moment, I'm just at a loss as to why it works
for some but not all. I'll plan on buying some different hardware in the
second week of August and revisiting it at that time.
For now, I'm working on the bootscripts. Some changes are required in
the standard boot order from the Makefile.
