I had the same issue in a ZBook G5 but interestingly enough I got this working.
Some background: I had used the Nvidia drive 460 with success. However due to a small mishap, I had to reinstall Ubuntu. Second time around, though I go the error reported here. I tried installing the drives directly via the "Software & Updates -> Additional Driver" application and via the packages (never NVIDIAs scripts). But these did not work. But the following 2 steps seemed to get this doing: 1. Configure the use of the suspend and resume scripts shown here: https://download.nvidia.com/XFree86/Linux-x86_64/460.39/README/powermanagement.html 2. Use the "Software & Updates -> Additional Driver" application but use the "NVIDIA Server Driver metapackage ... (proprietery)" and *not* the "NVIDIA driver metapackage ... (proprietary, tested)" Tests show both NVIDia profiles work now on resume. It would be interresting to get feedback from others. If this in fact does work, then one needs to know what is the diffference between the above two options.
