My latest kernel installed after upgrading from 14.10 to 15.04 is:
linux-image-3.19.0-15-generic
To boot properly into that one, I have to use the safe mode and then resume as described in this bug report. It works, but then my second screen isn't enabled.
I noticed when I boot into an earlier kernel, there are no problems, for instance:
linux-image-3.16.0-34-generic
Booting in this kernel, gives me a proper working screen.
