While tinkering today, I managed to bring my ZaReason BigLap to its knees by installing an incompatible video driver. No matter, James’ post over at elwoodicious guided me to my /etc/X11/xorg.conf file, which I thought I’d probably have to nurse back to life using his xorg.conf as an example.
But somebody upstream in my Kubuntu stack was thinking ahead: hey, this guy doesn’t know what he’s doing when it comes to video drivers. When I rebooted to command line, I found backups of all my interim xorg.confs from earlier this afternoon. Replaced the corrupted one with a backup just by looking at the timestamp, resumed the boot process, Booyah Achieved.
