Thanks to everyone for their help with my xterm font problem. It appears the XTerm.ad file is used to set the resource, and that for my account the font for fixed is Helvetica under KDE. Judging from current cvs, XTerm.ad no longer sets the font resource at all. However, the date of the fix to http://bugs.kde.org/show_bug.cgi?id=11898 appears well before 2.2.2, so there are still some loose ends. I sent Stephan Kulow, who committed the fix, a query.
But on to the next problem. While trying to verify what my fixed font setting was, I opened the control center. It's in bad shape. The icons/tree appears at the left, but nothing else. There is no vertical bar separating that pane from the rest of the window (I recall there was one), and nothing is displayed when I select an item except a blue band, the height of a normal line of text (or of the icon) stretching to the right hand side of the window. Any ideas what's going on? My first thought was that some KDE 3 elements had snuck in (I'm in testing), but as far as I can tell they haven't. 2nd possibility: font troubles again. I have a lot of font problems, including invisible and missing fonts. And I've been fiddling with fonts while working on the other problem, including taking bit-mapped fonts out of XftConfig (which I think KDE 2 uses--but I also think it can't handle bit-mapped fonts). And anyway, I don't see an empty pane, but just a highlighted line stretching across the window. 3rd possibility: it's been like this awhile, and I just haven't noticed. I would upgrade to KDE 3.1 and be done with worrying about KDE 2.2, but I lack the disk space to do so until I do some housecleaning. Plus I'm having a lot of problems, and it might be wise, or at least informative, to solve them before upgrading. Random thought: I've noticed some other windows coming up that stretch way off the right of the screen. I don't know if they're infinite, but they are certainly large (most apps fine, but Advanced Editor shows this problem). Perhaps the part with the tree for KControl is suffering from the same disease, and crowding out the right-hand pane.
