If you only knew how much I love that this was voted down. The entire incentive system for "helping" people on here is broken and perverse. People who do not buy into your incentive system fully are discouraged from helping at all. I've been helping people for years and have never needed someone to offer me "reputation points". Just weird.

So, here's the thing... It wasn't a bug, it was a mis-configuration. How do I know? Because I had the same problem and I fixed it myself. The solution: edit /etc/gdm3/custom.conf to include the line: WaylandEnable=false This detail matters because the author of the original question states he has an Nvidia GPU, which is broken with Wayland and is what is causing the sleep issue. Too bad nobody will see this because it was down-voted and a comment that is wrong was up-voted. I guess "it's a bug" has been decided...
