<PRE>This is explained in Bug 4742:
<A HREF="https://bugs.mageia.org/show_bug.cgi?id=4742">https://bugs.mageia.org/show_bug.cgi?id=4742</A>

But to summarize, xscreensaver-demo in Cauldron does not work, it comes up with an empty list of screensavers.  This list comes from reading the &quot;programs&quot; entry of the /etc/X11/app-defaults/XScreenSaver file, which is read using the XrmGetResource API of libX11.

XrmGetResource calls XrmQGetResource (in src/Xrm.c) which starts by doing:
if (db &amp;&amp; db-&gt;linfo.lock &amp;&amp; *names) {

and if that is false, it refuses to even try to read the entry from the app-defaults file.  I ran xscreensaver-demo in gdb, and db-&gt;linfo.lock is 0, so this doesn't work.  In Mageia 1, XrmQGetResource starts with:
if (db &amp;&amp; *names) {

and although db-&gt;linfo.lock is still 0, it doesn't matter and it works.

Can we patch our libx11 to go back to the old way, or is there a better way to fix this?  I don't have a deep understanding of the meaning of this code.  Maybe Thierry or someone else does?
