I have some additional data about this bug. Just restarting X doesn't trigger xrandr to re-poll for the new monitor. I have to reboot before I can connect to a new external monitor.
I also found a ton of these lines in my /var/log/messages: Nov 27 22:07:16 x200 kernel: [ 474.120523] i915 0000:00:02.0: VGA-1: no EDID data Nov 27 22:07:16 x200 kernel: [ 474.126200] i2c-adapter i2c-0: unable to read EDID block.

So could this be an issue with i915 or the i2c modules? $modinfo i2c_algo_bit filename: /lib/modules/2.6.31-16-generic/kernel/drivers/i2c/algos/i2c-algo-bit.ko license: GPL description: I2C-Bus bit-banging algorithm author: Simon G.
