Okay, thanks to some bad memory, I've been working through numerous kernel panics. It's only now that I realize that I cannot use X11 anymore, as well as NeoOffice. So, GIMP is non functioning as well as my word processing suite. I tried removing and reinstalling X11 and it has not helped. Basically X11 opens, then quits (no error report) and takes whatever application was depending on it with it. I'm loathe to re-install the operating system, but I'm afraid an archive and reinstall will transfer whatever has X11 and NeoOffice broken over to the new install. Can multiple kernel panics do something like this?
