All, I have noticed that when looking at kcontrol Appearance/Themes Screensaver, the dialog begins to open, then kcontrol crashes. This happens every time. On an odd instance, all of the screensavers will appear, but now it craters 100% of the time. I have looked at the xsession-errors log and it indicates the following: [tdeinit] Got EXT_EXEC 'tdecmshell' from launcher. libpng error: IDAT: invalid distance too far back OpenGL Error: DLL Loader couldn't find/open VBoxOGLpackspu.so X Error: BadWindow (invalid Window parameter) 3 Major opcode: 19 Minor opcode: 0 Resource id: 0x3800006 Apparently, the file that cannot be located is hidden in plain sight: 14:22 valhalla:~> find /usr/lib -name VBoxOGLpackspu.so /usr/lib/VBoxOGLpackspu.so I can confirm that the crash corresponds to the 'OpenGL Error: DLL Loader couldn't find/open VBoxOGLpackspu.so' message, but why is it not finding the file it is looking for at /usr/lib/VBoxOGLpackspu.so? -- David C.
