I first moved .xinitrc out of the way so I would load the default wm, "twm". It only took a couple of days and I lost the mouse cursor. I had a spare slice on a separate disk, so I installed the i386 version of 7 Beta 2 from CD. I updated it to stable and installed most of my packages, including XFCE4. I made the mistake of copying over all of my config files from the AMD64 version and the problem recurred. I then cleaned all of my packages with pkg_delete *. I cleaned out my home directory and /usr/local. I then reinstalled all of the necessary packages. It took a few says but it happened again. I moved my .xinitrc out of the way and was using "twm" since last Friday. About an hour ago I returned to my computer and the mouse cursor was missing. Evidently, the problem is something to do with my hardware that the "nv" driver does not like. I guess we can close this out as weird hardware problems. For the record, here is what I have: A8N-VM motherboard with 2 Gig of RAM (4x500) CPU: AMD Athlon(tm) 64 Processor 3200+ (2009.16-MHz 686-class CPU) On board video is GeForce 6100 Wireless mouse and keyboard through a PS2 KVM (happened before the kvm installed) If anyone needs more information I will be happy to provide it but for me, I will just live with it.
