I wish to add on a couple of details.

First, if the external monitor is plugged in when I boot the system, I can freely switch between laptop monitor and external without problems. If I ever unplug the external monitor and plug it back in, or if I plug it in after the system is booted, then trying to run any xrandr command (including xrandr --dry-run) locks the system.

Second, I find that in /var/log/messages, I have a block of 20 to 30 ^@ characters and then normal bootup messages, as if the last program logging to syslog dumped null data before crashing and then the system booted up normally.
