--- Comment #2 from Sebastian Rose rose@semkath.de 2013-02-24 16:57:38 --- That explains why the 3 monitor setup works, but 2 monitors plus a projector don't: two of the monitors are the same. Interestingly enough, it works completely fine for any kernel < 3.7.0. I have been using this setup since at least a year or so and never had any problems with 3 different display units (until 3.7.0). Considering what you said that confuses me, since it shouldn't have worked as problem-free as it did, should it?
