I get that *some* lib was a likely candidate, and that reinstalling the right
package should be the solution. What I don't see is the connection between
the error message and the package name string "kdelibs4c2a" that Mike
correctly identified.

Likely a combination of user error and package mangler error. I had tried to
update to v14, but after an hour of seeing upgrade candidate messages scroll
up the screen without noticing evidence of actual progress, I Ctrl-C'd out,
restored the old sources.list, and from there dont' remember what I did and
didn't do. I've since done an update that included somewhere between 250 &
300 packages, and all seems good now with that installation.

As it's a multiboot machine, with old HD and new Asus A88X-Pro
motherboard/RAM/CPU/video, I have to get all working acceptably, and I've hit
another big snag Google isn't helping with. The owner's vision is somewhere
in the bottom 2%, very poor. One of his workarounds is using a 42" TV screen.
Another was apparently installing/configuring some accessibility package that
made his mouse pointer easier to find in KDE3 in openSUSE 11.3. Using his
11.3 user data for a fresh 13.1 installation, his mouse pointer totally
disappears as soon as login painting completes, and it stays gone. With a
virgin user the pointer works normally. I've tried going through
.kde/share/config/ looking for mouse configs to zero out, but that hasn't
worked, and neither has looking for suspect package names among a complete
package list. I found he had downloaded 140787-LargeCursors.tar.bz2 and
installed that, but no help from it either.

Also, many sound devices are showing up in lsmod, apparently confusing both
automatic and manual configuration attempts. Alsactl init in Squeeze returns
instantly, writing nothing anywhere I can find. According to YaST2 on
openSUSE 13.2, there are 2 "cards", ATI as card0 using snd-hda-intel, and FCH
Azalia as card1, also using snd-hda-intel.
