Hi, Folks, and Merry Joyous Happy Ho-Ho Winter Solstice Thingy,
Just thought I'd drop a little info on y'all today (won't have time tomorrow and I would have probably forgotten it by then, anyhow...)
If you upgrade a machine with a "clean install" of PCLinuxOS 2010.xx KDE4, but you preserve the user's ~home folder, you may notice a ghostly square that covers the upper quadrant of the screen, and leaves a trace running down the middle and to the left.
In my case, it was my wife's computer, and I had just convinced her she finally needed to upgrade away from Mini-me 2008 to be able to do more with it about a month ago. We did the upgrade, and she asks me Tuesday why her screen has this odd ghostly rectangle traced on it...
I racked my brain, I checked everything I could think of - no dice. Hmm... look at another user (e.g., the root user), and no problem whatsoever - then it hits me: the wife still has a .kde3 directory in her ~home! Look a bit, scratch my head some, then decide, "whiskey, tango, foxtrot, over?" and delete the .kde3 folder.
Voila, the ghostly rectangle disappears! So far, no ill effects on any other programs except abiword, and that turned out to have another solution already posted here
So... y'all don't drink too much wassail, eggnog or other adult beverages during the holidays, and stay safe! (If you do drink, for sure don't drive!)
Peace, Love, and PCLinuxOS!
