I've since spoken to other people, and I've had it suggested to clean my
laptop's fans. Perhaps the frequent slowdowns is from something as
simple as overheating GPU. I'll give that try first. I also upgraded my
nvidia drivers, and the latter problem of the complete optirun crash
hasn't occurred since then (although it was intermittent previously).

I'm not sure sure about that. As I mentioned previously (below), I get
the same (abbreviated) error message under "normal" conditions when no
optirun applications are running. It seems like that error message is
possibly unrelated to my crash. It seems like it's just reporting an
error in the log?

Thanks again for the reply. Cheers,
Lee.
