Addendum to report: It turns out that my Horiz/Vert timings were off.
I consulted my monitor's manual (blew the dust off it, in fact) and
noted that the settings that dpkg-reconfigure chose for it were
incorrect. They've been incorrect for about a year, but something in
the most recent release ran into that bug.
