I see that the Developers have added "libglvnd" to the Tumbleweed repo:

From that thread, I deduct:

Add the repro which appears to be:
zypper addrepo http://download.opensuse.org/repositories/X11:XOrg:libglvnd/openSUSE_Tumbleweed/X11:XOrg:libglvnd.repo
zypper refresh
zypper install xorg-x11-server
Get the latest Nvidia prop driver,
Patch it
install it

So once all that is installed, How do I actually use it, i.e., make my mukless system use the nvidia card with the Nvidia prop driver vice the intel card?
Is it automatic?
Where & what are the options if any?
Does it work with Nvidia Prime?
What else do I need to do before I start -- like remove some packages?

Thanks for your insight!
