Earlier today I left my desktop machine to attend some presentations.
I left the screen locked (via xscreensaver-gnome-4.06). When I came
back, I found the system at the xdm login screen. I figured at the
time that in my hurry to get to the presentation, I must've selected
"Log out" instead of "Lock screen" from the GNOME panel.
Later, I discovered my machine had actually rebooted after a panic,
apparently induced whilst running the "starwars" screen saver:

I installed the NVIDIA drivers for FreeBSD shortly after their
availability was announced. I also upgraded my kernel and userland
~Nov 15 in light of some recent security advisories. Prior to this,
I've never encountered any panic whilst leaving my screen locked.
As an aside, I know the NVIDIA drivers are for 4.7-STABLE (which I
run). But, if I build and install a new kernel, do I need to
re-download and re-install the NVIDIA drivers to make sure they are
still in sync with the kernel I have now? (It's conceivable that in
the kernel upgrade some kernel data structures/API *may* have changed
relative to the one for which the NVIDIA driver I have was built,
rendering the existing NVIDIA driver incompatible.) So, what is the
best way to keep the NVIDIA drivers "in sync" with my system?
(Or, in lay terms, how can I tell if that panic was due to a bug in
the NVIDIA driver or due to an out of date module?)
Cheers,
Paul.
