515.76 has no prime support?

can’t tell if this is a bug or normal thing. i updated to nvidia driver version 515.65 to 515.76 and the prime support appears gone. as does opengl and vulkan. is this a bug or is that some sort of cuda only driver? how would i enable prime on this driver if it isn’t a bug. i had to install this version from nvidia’s site

uninstalled the broken propriatary driver and well… Traceback (most recent call last):

somehow have prime now after instaling 5 diffrent things, but i am havng trouble. roblox uses xdg open, and cause of this, it bypasses the flatseal rule to use nvidia card, any idea how to fix this? blender also has trouble
