I only use FOSS DDX, so cannot make any such suggestions.
The FOSS driver gives me a non-black screen, but is very slow in painting it.
There are these FOSS drivers available for NVidia graphics: FBDEV VESA Nouveau DDX Modesetting DDX The first two are generic, primarily for emergency and/or troubleshooting use. They are both very very slow. Normally one of the first two is used for X when the nouveau kernel driver is blacklisted. The Nouveau DDX and/or kernel's nouveau are typically blacklisted when a non-FOSS NVidia driver is installed. This prevents use of the two competent FOSS DDX. I believe this accounts for your "very slow in painting". I would like to have seen your Xorg.0.log and/or 'inxi -Gxx' output from before installing the NVidia drivers to be sure. The blacklisting probably survived the upgrade from 15.0 to 15.1, without a corresponding NVidia driver matching the 15.1 kernel. The modesetting is the upstream default, but a default openSUSE installation installs the upstream optional xf86-video-nouveau DDX package, preventing its use until such time as the optional DDX is uninstalled, or the modesetting DDX is specified through /etc/X11/xorg.con*. I use only the modesetting with all non-ancient NVidia graphics that it supports. Its every bit as fast as my eyes can follow on 2560x1440. I had a 3840x2160, but returned it for several reasons, among which eyestrain trying to configure it to eliminate the eyestrain. -- Evolution as taught in public schools is religion, not science.
