You got it.
I've found 'KSystemLog' really useful in helping to see clearly what is what, then being able to search around the internet including this forum with the datails provided.
For example on my system Xorg.log keeps popping up an information message:
"FreeType: couldn't find encoding 'iso8859-14' for '/usr/share/fonts/drakfont/ttf/LiberationMono-Regular.ttf'"
I've tried everything I can think of to fix it. Apparently, it's a bug inherited from Mandriva. Perhaps a future update will take care of it.
I haven't noticed any hit to system performance so I try to ignore it as well and not to let it get to me. Although... I could after all the time I've spent trying to make it go away.
