Status of multi-monitor support

[Guillaume Pothier]

Hi, I'm starting to get a better idea of how all of this works now. I
started hacking on plasmaapp. Kephal will actually make the code
simpler as it provides finer-grained signals (screen added, removed,
moved, resized), so the behavior of adjustSize can actually be split
between the corresponding slots (I started doing that).
Question: Plasma::View has an "int screen" attribute, that currently
indicates "the xinerama screen number; -1 for no screen". Is that ok
to replace that with a "kephal::Screen *screen" attribute? I think it
should be ok, as kephal would be ultimately responsible of choosing
between xrandr and xinerama, hiding those details from plasma. Or
maybe the attribute could remain an int, but it would be a kephal
screen number instead of a xinerama screen number?
