Install Nvidia Optimus Graphics Drivers on Fedora 26
※ Download: Install nvidia drivers fedora
You can find which driver you need here: My install script was: dnf update dnf install akmod-nvidia-340xx. You should disabled it or after a successful installation of the kernel module you must sign it, which is not the goal of this howto.
Configuration for headless systems Your system might only be used for CUDA development and not require the X server to be running the driver at all, so you might want to tweak the configuration a bit to make the system load for example the Intel driver as the main display and just the Nvidia driver for calculation. Every time dracut runs, it will consult the following list and make the necessary exceptions when creating the initramfs image. The PPA is currently in testing but you can nonetheless get working Nvidia drivers from here.
Install Nvidia Optimus Graphics Drivers on Fedora 26 - You should disabled it or after a successful installation of the kernel module you must sign it, which is not the goal of this howto.
Until recently, I have never had an opportunity slash bothered to try on a system with Nvidia drivers. I did a similar thing with other RedHat family distros, like CentOS and Scientific. But not Fedora, and I did encounter some issues. In this guide, I will show you several methods how to safely install Nvidia drivers in your Fedora distribution so that you can make the best of your graphics card. Today you will learn how to approach the problem and get the system up and running, as well as recover from potential bodges that may arise. Anyhow, enough teasing, after me, lads. System running, system updates The very first thing you will want to do, once your Fedora boots, is to fully update the system. This is crucial, because you want the running kernel and kernel headers, identified by the kernel-devel package, to be identical before installing the Nvidia drivers, otherwise the procedure may fail. Repeat until no more updates are available. Nouveau out, Nvidia in If you browse the Web carefully, you will notice many guides telling you how you can discover whether your machine is Nvidia-capable so to speak. I will skip this step, because the whole reason you're here is because you know that your machine has an Nvidia card, and this is why you want the appropriate drivers for your system. However, if you still feel somewhat insecure, check my Linux guide first. Now, on Nvidia-enabled systems, by default, you will have the open-source Nouveau driver running. It will have to go before you can use your Nvidia driver. But we will not try anything manually for now. We will attempt simple, automatic methods first. Additional repositories You will need to configure additional repositories before you can search and install the desired drivers, because Fedora only ships with FOSS stuff by default. I have highlighted how you can configure repositories in a RedHat-family friendly repo , originally written for , but still quite useful here. Alternatively, you can use a tool like , which will do the same thing for you. It will automatically configure the extra repositories, like RPMforge, renamed , and then allow you to install the Nvidia graphics drivers. If you do not feel comfortable using this tool, you can then install the drivers on your own using the yum package manager from the command line. Basically, what you need is: yum install akmod-nvidia xorg-x11-drv-nvidia-libs The first package, akmod-nvidia, will automatically recompile your kernel module for new kernels on every boot, if necessary, which means you will not have to manually reinstall drivers every time there's a kernel update. You can also try kmod-nvidia, for that matter, only you might not have the comfort of automatic driver updates. After the driver is installed, you can reboot. In theory, you can just stop the graphical interface, unload the Nouveau driver and load the Nvidia driver, but that's too much hassle for most people, so reboot is a much simpler option. Indeed, if everything went well, you should have your Nvidia driver up and running. Problems with Nouveau, black screen You may end up with a black screen instead of a lovely, usable desktop session. There are many reasons why this could happen, but in your cause, it's probably a conflict between graphical drivers or the desktop session configurations. You will need to work on one of the virtual consoles Ctrl + Alt + F1-6 to try to resolve your problem at this stage. Verify Nouveau is not loaded To do that, you will need to use the lsmod command, best as root: lsmod grep nouveau If you get any naughty output, it means the driver is loaded, which explains why Nvidia is not, which would explain why your desktop session is misbehaving. Therefore, we need to disable Nouveau. We will first try a one-time blacklisting from the command line before creating a permanent blacklist rule. If the system enters the graphical session, and the Nvidia driver is properly loaded, then all is well. You will just need to add a manual rule that blacklists Nouveau from loading. Again, this can be done permanently by editing the GRUB command line, or by creating a module blacklist rule. For the first, you have more than extremely detailed and GRUB2 tutorials to get the desired results. A more elegant way is a permanent blacklist. Every time dracut runs, it will consult the following list and make the necessary exceptions when creating the initramfs image. Of course, you will need to make the initramfs file the first time after creating the blacklist rule. Personally, I recommend the GRUB change, because it is so very easily reversible. And don't forget backups, because if something wrong, you will be able to recover easily. The file is created on Nvidia driver installation, or at least modified from whatever was configured earlier. To that, you might want to move this file aside, creating a backup, then restore Nouveau and boot, to see if this fixes the problem. It is also possible that you may have already moved this file aside, and now that Nouveau is disabled, Nvidia can load, but there's no configuration in place. Manual method This is your last resort. However, luckily this procedure is identical for most distributions out there, including the Ubuntu family, and friends. You will need to install all the necessary build tools first. Then, you will need to drop into runlevel 3, followed by a manual installation of the Nvidia driver. Finally, load the graphical session.

That's the sensible way of doing, but you know. Anyhow, this guide has taught you many things. First, how to add new repositories to our Fedora. Then, how to use easyLife or manually install Nvidia drivers. We also learned a bit about compilation and build tools and such. We then debugged driver problems, learned how to blacklist modules using GRUB command line or the system modprobe list, how to edit or fix the Xorg configuration file, manual install, and still more besides. And we have references for Ubuntu, openSUSE and CentOS, so it's all milk and honey from here on. Which makes this guide one hell of a useful thing to keep around.
To determine which driver you need to install, you'll first need to find your graphics card model. Unfortunately, NVIDIA provides many services that are simply indispensable for many researchers. Problems with Nouveau, black screen You may end up with a black screen instead of a lovely, usable desktop session. When I try to reboot, it never reaches the Graphical login interface. Can you please help me with this configuration. Determining your card model NVIDIA has several driver series, each of which has different hardware support. X -configure Copy xorg. Again, this can be done permanently by editing the GRUB command line, or by creating a module blacklist rule. It contains a SUID binary that creates the device files and set the appropriate permissions when automatic device creation is not available. Download drivers using following link.
