Does AIX support the Xrandr extension?

[Volker Simonis]

Hi Ichiroh,

thanks a lot for the pointers.

Up to now, I tried to only depend on "official" IBM packages (i.e.
original AIX packages or packages from the "AIX Toolbox for Linux
Applications" [1]) for both, the build and at runtime. I'm not sure
how "reliable" the packages from perzl.org are, but in general I want
to avoid unverified dependencies.

That said, I don't know Xrandr makes any sense on AIX at all. As far
as I can see, it hasn't worked until now anyway. Or can anyone report
any successful usage of Xrandr on AIX with these packages?

Thank you and best regards,
Volker
