Have have the package referred to installed and I have also got the oyranos package from slackbuuilds.org installed.

Neither of these installations appear to have provided a KDE system-settings color management icon through which one might be able to set color profiles for all CMS-aware applications. I can set relevant color profiles (through .icc files) for those applications which explicitly allow that (eg GIMP, digikam) but the idea of these more general purposes packages is that you should be able to set (for example) your monitor profile for all apps which can make use of it.

Looked through Alien Bob's ktown repos but cannot find kolormanager or anything like that.

Anybody know how CMS should be implemented in KDE (or XFCE) ?

Thanks.

I've been using dispcalgui, it does the trick with the help of argyll cms and calibration hardware. You should be able to load a monitor profile using argylls utilities or xcal. I don't know about kde, sorry.
