Recently, I have upgraded Opensuse Leap to version 15.6 on 5 PC-systems – all with (different) Nvidia graphic cards. I sadly must say that the present Nvidia driver of version 570.86.16 is, at least in its corporation with the kernel and other components of the present Leap 15.6, unreliable or even buggy:

The resume process from “Suspend to RAM” does not work reliably on any of the systems.

I get black screens with only the mouse cursor showing up, on other systems totally black screens, on some systems the SDDM login screen turns up after more than 2 or 3 minutes wait time – but not always.

Unfortunately, after many experiments, I have no real solution for this. You can try to go backwards to driver version 550 – but due to complicated package dependencies this is no easy endeavor either.

Therefore: Linux admins who have not yet updated Nvidia drivers to version 570 should keep their older versions.

Version 570 is the last available one of the Nvidia driver in the Opensuse repositories. It is not the official stable version – which actually is 550. Why the Opensuse people have placed the 570 version already into their repository can be discussed.

As energy saving is in my opinion something important, I hope that both driver developers and Opensuse developers solve this problem in the near future.
