OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU 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. See: https://git.reviewboard.kde.org/r/110314/ diff --git a/data/images/nickicons/alternative/irc_normal.png b/data/images/nickicons/alternative/irc_normal.png index 346500337b0ee0e0a16355e17e61beed87498396..848eed56f52346ebda109580d9d7693f108a870d 100644 GIT binary patch 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 See also: https://bugzilla.redhat.com/show_bug.cgi?id=1015691 If this png error is goofing something up in the tdecmshell code, it could be the root cause of the problem... -- David C.
