10.7.3 incompatibility?

[qthatswho]

Workaround posted in these forums is not working for me. I think this is because I cannot get into safe mode with an encrypted disk (FileVault2). I've tried resetting PRAM (Cmd-Opt-P-R) and resetting nvram, to no avail. Any time I plug in the DisplayLink adapter, I get a blue screen, and my machine is hosed (even sleeping and waking with displays disconnected does not recover.

I really need the use of my second display, even in landscape mode. Anyone else got any suggestions for resetting display settings?

Thanks,
