tdecmshell screensaver

That's what I was reporting when I got side-tracked with the "Is there a Master list of what is rename K->T or K->TDE"... It loads when called with tdecmshell, but not from kcontrol:

I can select and test all screensavers fine. So I was concerned that it was a problem with kcontrol killing the screensaver process when it would actually complete.

vboxvideo is loaded, so there is something preventing OpenGL/libGL from finding the libraries and modules despite being loaded and available...

I don't understand the libpng issue, but apparently something kde4 had to fix with a binary patch 'commit 7f6d066398eafb8b0bc5196d438e8d931cddcad8' to fix an icon. It was done by Andrea Scarpino at kde.org.

That may be something we need to do for TDE. I have no ideas what that icon would be doing in screensaver tdechshell??

Apparently you can use pngcrush or optipng to fix the image.

pngcrush -fix -force old.png new.png optipng -quiet -force -fix foo.png

If this png error is goofing something up in the tdecmshell code, it could be the root cause of the problem...
