This on the newer xorg-server with KMS options? We are using GDM as the login manager, not sure if that would make a difference. Also, this may be related or not, but I've seen a number of cases in KDE where it spins up "upowerd", and that takes 100% of a core. Can't find a cause for it though, seems like it happens at random times on my desktop / laptop, maybe once a week or so. I've got a couple of systems I'm leaving up again, will try to get some additional details on this. We've run into this on probably half-dozen systems at the iX office, and they ended up having to switch to LXDE as a work-around, but would prefer to run KDE :) -- Kris Moore PC-BSD Software iXsystems _______________________________________________ kde-freebsd mailing list kde-freebsd@kde.org https://mail.kde.org/mailman/listinfo/kde-freebsd See also http://freebsd.kde.org/ for latest information
