[gentoo-amd64] xinerama in xorg-x11-7.0-r1?

[gentoo-amd64] xinerama in xorg-x11-7.0-r1?

[Peter Humphrey]

I decided to install a Gentoo KDE system on this box, to try once again to 
find a way of giving it a civilised look, and while I was at it I thought 
it a good idea to try out the new X window system. I followed the howto at 
www.gentoo.org/proj/en/desktop/x/x11/modular-x-howto.xml and all seemed to 
go remarkably smoothly.

Now I'm looking around for oddities, and this one puzzles 
me: /var/log/Xorg.0.log says '(II) Initializing built-in extension 
XINERAMA'. I know the use flag is not set because 'USE="-xinerama" emerge 
-upDvN world' gives no packages to update, whereas omitting the minus sign 
causes a whole lot of packages to be updated (but not libXinerama).

$ qpkg -I -v libXinerama
x11-libs/libXinerama-1.0.1 *

What caused this library to be built? I see this:

$ equery d libXinerama
[ Searching for packages depending on libXinerama... ]
x11-base/xorg-x11-7.0-r1
x11-apps/xdpyinfo-1.0.1
x11-libs/gtk+-2.8.12
x11-libs/qt-3.3.4-r8
x11-libs/qt-4.1.1
kde-base/ksplashml-3.5.1

Is this a problem, or am I just being fussy? Quite possibly, the 
modularisation of X is not yet finished and this small anomaly will go away 
soon.

It isn't that. I looked in the corresponding Xorg.0.log on another system on 
the same box and found the xinerama extension being loaded there too, in 
spite of the use flag's not being set there either.

So the question is why X is being compiled with xinerama support when it's 
been told not to.

I'd still be inclined to consider it an issue with the new modular X. 
Not all is yet entirely smooth going with it.

Also note that Section ServerFlags of xorg.conf can contain an Option
"Xinerama" line.  Previously, even if Xinerama support was compiled, it
was off by default unless you had that option listed and it wasn't toggled
off in the option (the option defaults to on if found, so on doesn't have
to be specified).  Assuming you don't have that option listed, perhaps
the default has changed, and it now defaults to on under certain
circumstances?

I wouldn't have noticed it here as I run dual monitors (altho I have
xinerama off because I'm running the radeon driver in merged framebuffer
mode, with its pseudoxinerama, so I don't need the extension turned on) in
xinerama mode (well pseudoxinerama, without the extension, as explained).

I'd check and see if there's a bug on it, and consider filing one, if not.
If the change is intentional, it should no longer have that flag, so
obviously, there's either a bug in the support being added, or in the flag
still being there but not honored.  That's a bug that needs filed, unless
there's already one on it.

Ok.

Perhaps, but it seems odd that the feature has been compiled in at all. And 
no, I have no such line in /etc/X11/xorg.conf.

Ok. Done.

Because the xinerama USE flag doesn't apply to x.org?

The xinerama use flag enables support for the extension in clients. 
It is a hard dependancy of an x.org server installation however.

Indeed, it seems to be.  I don't see the flag there any more, altho I
could swear it used to be.  <shrug>

Boy, I seem to have hit a bad streak of "wrong", lately. =8^(

You are not wrong here!  From the changelog:

  02 Nov 2005; Donnie Berkholz <spyderous@gentoo.org>;
  xorg-x11-7.0.0_rc1.ebuild:
  Remove xinerama USE flag and make it mandatory. A large number of
  applications have mandatory xinerama, so having the library optional makes
  things unnecessarily complex.

Thanks!  That makes me feel better! =8^)  Such a string of bad luck, I was
beginning to wonder if this is how Alzheimer's or mad cow disease starts
or something, especially when I could have sworn the flag was there!

I must have figured things out and merged it right about time they removed
the flag.
