I tried KDE (which is great), but this required the NVIDIA driver. However, this driver conflicts with my modem. If the driver is loaded, then the system locks up when accessing the modem. If I remove the NVIDIA driver from /boot/loader.conf, modem works fine. I tried moving the modem to different slots, but no joy. (The modem likes the slot it's in, but not the others.) Any help would be appreciated. System running 4.8-STABLE with X11 & NVidia built within last week.
