    gentoo is about 'doing it yourself' and 'emancipation of the user' and not
    about 'holding your hand'. It is not gentoo's fault if you act stupid.

    Section "Monitor"
           Identifier   "Monitor0"
           VendorName   "WDE"
           ModelName    "LCM-20v5"
           Option      "DPMS"

  Opinions differ about what constitutes stupidity.  I'm not much interested in yours and I don't speak about mine, in part because neither one clarifies anything.  Opinions about usefulness are another matter. Why not dispense with portage and have everyone compile their own from tarballs -- just publish a list of packages and patches; then you'd really not be holding hands.  It seems to be a matter of degrees and judgement.

  Modifying the monitor section made no noticeable change.  There's still a 24-pixel bleed off the right edge to begin with.  I can fool with settings to make it bleed left instead, but there's no setting that affects pixel spacing.  I like the cleaner monitor section, though.

  I'm back to thinking about modelines.  Any better ideas?

  Let's not rule-out the possibility that this might be an issue with a bad video card. I once thought I had a bad monitor because of horizontal and vertical bleeding and it turned out to be the video card. Try the modelines, if it does not work, swap video cards. Below is a section pertaining to modelines from my config. User gtf  to generate proper modelines for your monitor.

  you can omit the identifier if you don't have a 22 inch minitor.
