Bug 4868

It's removed because fedora plans to update to xorg-server- 1.20 after GA.
It's unknown when nvidia will release an updated driver for 340xx, and we won't hold xorg-server 1.20 for such legacy release.

So plan is to re-introduce this 340xx driver once the xorg-server 1.20 support lands for f28+

Please grab the driver from f27 as a workaround.

340xx has no active maintainer.

Do you mind explaining how to do that?

Hey ufa,

To install the nvidia340 drivers from fedora 27 on fedora 28 you need to download the RPM packages from https://fedora.pkgs.org and install them manually.

I made an install guide for anyone that needs help doing this:
http://pc.cd/LtrctalK

I also uploaded the RPMs (64-bit only) to my pCloud to make it easier for anyone else that needs to use this workaround. Download link:
http://pc.cd/73gctalK

Hope that helps!

Thank you p0wnder, but it didn't work.
I was greeted with the sad computer face, that happened when I booted fedora 28 the first time after the update from 27.
But thanks anyway

Did you disable SELinux?

In order to install the 340xx serie on f28 with rpmfusion one can do:
dnf install xorg-x11-drv-nvidia-340xx kmod-nvidia-340xx --releasever=27 --nogpgcheck

(Use nogpgcheck if you haven't already imported the f27 rpmfusion-nonfree gpg key).

This is documented at 
https://rpmfusion.org/Howto/NVIDIA#Latest.2FBeta_driver

Please keep in mind this is not supported yet because the xorg-server might be updated to xorg-server 1.20 in f28, breaking this driver.

When nvidia will release an updated driver for xorg-server 1.20 we will re-introduce the driver in f28.

Hi Nicolas,
thank you for your reply. I am still unable to use the NVidia driver on Fedora 28. 
I think it may have something to do with the 4.16 kernels. On my dmesg:

[seg mai 28 11:58:49 2018] ------------[ cut here ]------------
[seg mai 28 11:58:49 2018] Bad or missing usercopy whitelist? Kernel memory exposure attempt detected from SLUB object 'nvidia_stack_t' (offset 11864, size 3)!
[seg mai 28 11:58:49 2018] WARNING: CPU: 1 PID: 997 at mm/usercopy.c:81 usercopy_warn+0x7d/0xa0

...

I would stick with nouveau, if it didn't random freeze my system from time to time. 

Best wishes.

Maybe you could have a look at patches produced for 340xx serie of nvidia drivers, or even any others series.

This is likely that the nvidia-340xx driver will already need patches for 4.16 kernel on f27, so one would need to update the package.

Is this the driver we are waiting for?

"Added support for X.Org xserver ABI 24 (xorg-server 1.20)."

Never mind, it's a different version from 340.xxx

NVidia has now released a version of the 340.xx drivers with the following fixes:

"Updated nvidia-installer in the 340.xx legacy driver series to default to installing the driver without the NVIDIA Unified Memory kernel module if this module fails to build at installation time. The 340.xx legacy Unified Memory kernel module is incompatible with recent Linux kernels, and the GPU hardware generations that the 340.xx legacy driver series is intended to support do not support Unified Memory.

Added support for X.Org xserver ABI 24 (xorg-server 1.20)."

This may allow the 340.xx drivers to be built.

Oops, that was a link to the ARM driver.  Here's the link to the x86 driver.

Apparently we need someone to maintain this package... even if it is a minimal one excluding stuff like cuda.

We always need volunteers to maintain packages.

I might be doing something wrong, but I don't see the kmod-nvidia-340xx package on koji nor for Fedora 28.  Just the xorg-x11-drv-nvidia-340xx package.

I don't think that anything will work without the kmod-nvidia-340xx package?  Is this built and available somewhere?

I'm also having problems downloading and installing the driver. I think it is not ready yet.

Is it this?

There is an infra issue that prevented theses packages to appear
This is now fixed on the primary mirror and will be fixed on local mirrors in the next few hours.

It worked, thank you so much!

Confirmed that akmod-nvidia-340xx also works now under Fedora 28, including after multiple kernel updates and rebuilds.

Thank you so much!  

This prevents my not-really-old laptop from panic shutting itself down every 10 minutes (even when relatively idle) to prevent overheating and damage from the nouveau drivers.  These "legacy" drivers mean a lot to people who have perfectly usable but not-the-latest hardware.  Thank you.    Please keep these as a priority when new Fedora releases are made.
