After weeks of struggling with a once stable Fedora 27 with Hangs, restarts and "ooops something went wrong" screens, I found that now the AKMOD are available for NVIDIa. I checked various pages to check and seems that the following was the best option ( from RPM fusion )

dnf install xorg-x11-drv-nvidia-340xx akmod-nvidia-340xx

dnf install xorg-x11-drv-nvidia-340xx-cuda #optional for cuda up to 6.5 support

dnf update -y

SO, following the install and dnf updates, I installed it as su and did a ghard reboot - almost expecting the "oops something went wrong" as before Thankfully, this time Fedora28 started BUT with the following errors "NVIDIA Taints kernal" and suggested I use the Nouveau driver ( which hangs my system)

PLEASE can someone let me know how to get my Fedora 28 stable with an NVIDIa card as I really cannot spend more hours constaly reinstalling...I know that this is all here by the grace of some very generous hardworking people and I do thank you but I have lost so many hours now - PLEASE HELP

What is the best way to install NVIDIA drivers ? I have look ed at the NVIDIa page, the RPM page and thes epages and always end up with wrrors.. I tnever used to happen

Many thanks for all your hard work and hopefully for an answer

Tainting the kernel just means that the folks maintaining the kernel can't work on any kernel bugs you report because there are third-party, closed source modifications to the kernel. As long as your system works, or your kernel isn't crashing, it's not a problem. (Personally, I think they should try to reproduce the issue with a stock kernel to see if the mods are involved, and only close it if they can't, but it's not my decision to make.)

kernel taint is because you elected not to make a digital signature, when you installed the proprietary. I did not make one, so I also get the kernel tainted messages, but found no degradation in any of the operations on the system. I treat the kernel taint as a warning only, and just ignore it. if you do want to digitally sign the driver, so that SELinux likes it, the readme for the driver gives very detailed instructions as to what is expected.

go to this link, and download the driver version you want, I run the very last one, at this time it is 396.24 and I have zero issues with it. Even when kernels are updated, dkms will rebuild the module, and the new kernel will boot with the driver already installed. Can not get much simpler than that. after the start terminal, you can simply copy and past the steps, you might want to copy them to a text file and print it, so that when you reboot to text mode, you can refer to them.

start terminal

sudo -i
dracut --omit-drivers nouveau /boot/initramfs-$(uname -r).img $(uname -r) --force
systemctl set-default 

login as root

dnf install kernel-devel-$(uname -r) kernel-headers-$(uname -r) gcc dkms acpid
bash /dirofsavedfile/ 
systemctl set-default

if all goes well, you will have a fast video driver, that takes full advantage of the capabilities of your video card. My 970GTX with 4gig ram give a score in glmark2 of just over 5700 fps. Some of the tests are higher, but that is what the average is. if you have glmark2 installed, after you get the driver installed, run it as glmark2 --fullscreen and tell me your score, and what model of video card you have. I would be curious to know how it does. hope this helps.

I shall do this as soon as I have some other issues cleared up. Thank you Very Much and I shall report my test results ;-) BTW, my card is an old GT240

I recommend using the default open source drivers "nouveau" which are shipped as part of Fedora. Do not install 3rd party software which often fails to comply to basic API stability.

sadly, as I mentioned in the original post, the Nouveau drivers tend to make my system hang on a very regular basis - never have found out why
