Turns out it runs an Intel 815 video chipset, which is not supported by the updated version of the Intel driver (Bug <a moz-do-not-send="true" href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1389904">1389904</a>). My repair involved temporarily installing an ATI video card, then in Synaptic forcing a downgrade to the original version of xserver-xorg-video-intel, and finally locking that version of the package. So far the software updater seems to respect that. Then I removed the ATI card and successfully booted. But collateral damage included a broken plymouth splash screen. It is now a white screen with full-height thin vertical black bars and some occasionally recognizable pieces of the expected splash. I tried "sudo dpkg-reconfigure plymouth" and that did not fix it. Also in /etc/default/grub I un-commented and set GRUB_GFXMODE=1024x768 and then "sudo update-grub" but that did not work either. Does anyone know how to fix this? </blockquote> Aere Greenway on the Lubuntu list pointed out that I mis-observed. This behavior was already present even before I started troubleshooting, and I confirmed it with a fresh installation on a spare hard drive. </body> </html>
