I’ve had this issue with my PC (where sleeping would cause the system to not recover) I found something that worked for me online, let me know if you would like to try. But must admit it appears to have been sorted naturally now for approx a year or so at my end. This was a particular nvidia issue as well.

The clock may roll back to 1939.

But try changing it via tzsetup as root.

Hello, I’m far from an expert but I had a similar issue on my desktop, running mint and an Nvidia GPU. After looking at a lot of places for an answer one that did work for me was below

Ust/bin/Nvidia_sleep.sh. (off the top of my head it is something like this, can confirm later if you can’t find it.)

At the top put in “exit 0”

See if it works for you. But it seems when I get an update it does at times get overwritten.
