Please find below an email and patch by Rik Faith to make XTEST work with Xinerama. I have backported this to a 4.2.1 version on my debian box and it worked. Could someone add this to cvs? it shouldn't be a lot of work.
Thanks
Erik

[This was posted to [EMAIL PROTECTED] last week,
but I didn't get a reply. Sorry if you've seen it twice...]
I recently noticed that several extensions are not xinerama-aware.
For example, Extended-Visual-Information will report visuals for two
screens even when xdpyinfo reports only one screen present (i.e.,
because of Xinerama). I suspect an issue with MIT-SCREEN-SAVER but have
not investigated -- does anyone use an MIT-SCREEN-SAVER client with
Xinerama (beforelight seems to be the only one).
The XTEST extension performs computations relative to the internal
screens, even though a client (e.g., x2x) obtains information about a
single large Xinerama screen. Below is a patch to Xserver/Xext/test.c
that will fix this problem (against the xtest.c that should be in the
XFree86 4.3.0 tree). I have verified this patch does not alter the
results of the X Test Suite when it is configured to run with the
XT_EXTENSIONS=Yes flag. I have also verified that x2x works as expected
with this patch, and not without it.
I used: http://www.netsw.org/x11/extensions/x2x/x2x-1.27.tar.gz
(Note that because of the way the other XTEST code (e.g., IIRC, the
client-side library) is written, I was unable to write a xinerama-aware
client that could do anything to trick XTEST into doing the expected
thing. For simplicity, I suggest fixing it here.)
Thanks for your help, Rik Faith
