Hello,
I have installed the nvidia driver (390) from the RPM fusion page, everything seems normal, when I updated the 5.17.xxx kernel version the nvidia module did as well.
But now, I update the kernel to the 5.18 and my pc is using noveau, I tried to install again akmod + nvidia driver the same way as before, and the problem continues, the terminal tells me that I have already installed the nvidia drivers, but noveau still appears, I tried to blacklist noveau and the same problem.
Please help, sorry for my bad English
