It is not just Nvidia. Suspend to disk (hybernation) worked fine on my laptop for years. Then something changed in the kernel and now although it will hybernate, waking up causes all sort of failures and crashes. It is a kernel bug, I found out that someone reported it last year, but it has not been fixed yet it seems. On another PC both hybernation and sleep have gone through a cyclical pattern of working or not working over the years. Thankfully now they are working! :-) -- Regards, Mick
