It sounds as if the primary monitor is using DPMS in Xorg, if you're running X, or some similar energy saving feature. Check SystemSettings > Power Management > Display and Brightness. Meanwhile back at the ranch, I think my Gkrellm dock panel problem is related to KDE 6 not identifying the Gkrellm window as a 'dock/panel', probably because the Gtk2 code is far too old to integrate with Plasma. :-(
