Trouble installing Nvidia drivers and OS claims I got a graphics unit I don't have?!

Uh okay, so, I installed openSUSE recently on my desktop after a long dryspell where I only used Windows, and I just wanted to try out how well Proton on Steam works, hoping to get away from Windows for good this time. For that I wanted to install the proprietary Nvidia drivers so it wouldn’t run like ****.

Well now… it would only boot into CLI when I first did it, so I zypper rm’d it and took a look at what my PC says about that, wondering if I had to deinstall some other driver before that. And here’s the funky thing. I am running a desktop PC using an Intel i5 4670K. This is correclty identified by the OS. However… it also claims I have a Xeon E3-1200 display device. It doesn’t list it under CPU, it just lists it under display device… My GTX 760 is the only device I have installed.

Additionally, I have this package suse-prime for Optimus-related ****, which is clearly out of place on my desktop PC with no Optimus-hardware in sight. I can’t even remove it. WTF is going on? Is my installation broken? Should I reinstall openSUSE from scratch and try again? Could this mess have been introduced with a faulty nvidia driver installation, should I roll back to the state before I even attempted the installation? Has anyone ever even encountered this problem before? Is it supposed to be this way? This is mildly confusing and irritating.

And either way… for my booting to CLI problem, should I just blacklist nouveau as I did on my old broken T510 when I ACTUALLY had Optimus-technology installed? I’m kinda too depressed to try out everything right now so I’m hoping someone else with more experience or know-how has good answers. If I don’t get anything, I’ll go through the process some time later next week whhen I have the mental ressources and share my findings.

Thanks in advance for any attempt at helping me out.

What exactly is “it”?

also claims I have a Xeon E3-1200 display device. It doesn’t list it under CPU, it just lists it under display device… My GTX 760 is the only device I have installed.
Intel says you are sporting one of its GPUs. Confirm this by running ‘inxi -Gxx’ and/or ‘xrandr --listproviders’ and/or ‘lspci -nnk | grep -A3 VGA’ while X is running, by booting using nomodeset if necessary to get X to run, preferably without having anything blacklisted.

Additionally, I have this package suse-prime for Optimus-related ****, which is clearly out of place on my desktop PC with no Optimus-hardware in sight.
Prime for Optimus was made easier for those who need it back around February. Intel GPU + NVidia GPU is the foundation upon which Optimus is built.

I can’t even remove it. WTF is going on? Is my installation broken?
Maybe your BIOS is broken. Did you check in it to see about disabling IGP (Integrated Graphics Processor) or making PEG (PCI Express Graphics) the default or primary?

That can happen

should I roll back to the state before I even attempted the installation? Has anyone ever even encountered this problem before? Is it supposed to be this way? This is mildly confusing and irritating.

And either way… for my booting to CLI problem, should I just blacklist nouveau as I did on my old broken T510 when I ACTUALLY had Optimus-technology installed?
If it was here I would have worked through the CLI issue before attempting NVidia driver installation. Both Intel and NVidia GPUs can be run on the very same DDX driver - modesetting. To actually make both use modesetting typically requires a bit of setup, either an explicit driver specification in /etc/X11/xorg.conf, or removal of xf86-video-intel and xf86-video-nouveau.

Possibly what you are up against with the black screen issue is this nouveau bug in the 15.1 4.12.14-lp151.28.4 upgrade kernel. The release kernel 4.12.14-lp151.27.3 doesn’t have the problem, so maybe the place to start is to try the release kernel and remove the upgrade kernel.

Additional clues might be found by enabling boot messages to scroll by during init. Either hit ESC right after making your Grub selection, or edit the boot stanza with the E key to remove splash=quiet and append plymouth.enable=0, so that you might recognize where something is going wrong to leave you stuck in text mode.

Since this is a desktop machine it is not Optimus just has two GPU Intel and NVIDIA

You should be able to disable the Intel in the BIOS to simplify things.(generally not possible on Optimus laptops) Also be aware of the broken nouveau driver in the latest kernel. Either install the NVIDIA driver or drop back to the original install kernel
