I have figured out what I need to do to reproduce this bug. Basically, if I start the laptop without the external monitor, log in, and then switch from internal to external monitor using the screen resolution control panel, then everything works fine till the next reboot. Next time I reboot, if the external monitor is attached at boot, then the problem will occur. To fix, I need to log in, switch to internal display only, reboot with only the internal display, then switch back to external display. This is really annoying and takes a lot of time. It appears to definitely be linked to the fact that I started using the frame buffer device in order to be able to switch monitors.
