Fedora

You can download Fedora here:

• https://dl.fedoraproject.org/pub/fedora/linux/releases/

Create root password

$ sudo passwd root

Add user to sudo

# usermod -aG wheel cheo

cheo must log out and log in again for the changes to take effect

Update repository

There is a bug in Fedora 30 when trying to update the repository. Issue the command below only on Fedora 30:

$ sudo echo "zchunk=False" >> /etc/dnf/dnf.conf

• On Fedora 29 or 30, issue these commands:

$ sudo dnf clean all

$ sudo dnf update

Install CUDA drivers (not toolkit) and nVidia drivers

Important: these instructions assumes that Fedora 29 has been installed without an nVidia graphic card plugged in, in order to avoid the OS installation to setup nouveau drivers automatically. Nouveau drivers will prevent nvidia drivers from installing, so we don't want nouveau in our system.

Warning: There is a known issue with default Fedora 29 display manager GDM when installing the nvidia drivers: after login, the screen remains black. To solve this issue, follow any of these two solutions:

Solution 1

• Edit /etc/default/grub and remove rhgb from line GRUB_CMDLINE_LINUX="rhgb quiet"
• Rebuild grub config file:

## BIOS ##

$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg

## UEFI ##

$ sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Solution 2

Install a different a display manager. I choose the LightDM :

$ sudo dnf install lightdm

Disable GDM during the startup and enable LightDM:

$ sudo systemctl disable gdm

$ sudo systemctl enable lightdm

Reboot:

$ sudo reboot

CUDA driver installation

You can download Fedora 29 from here in case you want to perform a fresh install.

• Once Fedora 29 is installed without any nVidia card plugged in, download the Linux Fedora 29 x86_6 runfile(local) from here.
• Install de following packages:

$ sudo dnf install make elfutils-libelf-devel

Install the kernel headers and development packages for the currently running kernel:

$ sudo dnf install kernel-devel-$(uname -r) kernel-headers-$(uname -r)

• Regenerate the kernel initramfs:

$ sudo dracut --force

• Change default run-level to "3":

$ sudo systemctl set-default multi-user.target

• Turn off the computer

$ sudo poweroff

• Unplug power cable
• push power buttons in PC and monitor to release all condensed electricity
• Plug in the graphic card
• Turn on the computer
• Login from prompt
• cd to the directory where you downloaded Linux Fedora 29 x86_6 runfile(local)
• Install Linux Fedora 29 x86_6 runfile(local):

$ sudo sh cuda_10.1.243_418.87.00_linux.run --silent --driver

• Change default run-level back to "5":

$ sudo systemctl set-default graphical.target

• Start up X:

$ sudo telinit 5

Reboot

Check graphic drivers in use:

$ lspci -nnk | grep -i vga -A3 | grep 'in use'

• Check CUDA and nvidia version installed:

$ nvidia-smi

Install Davinci Resolve 16

• Install a necessary package first:

$ sudo dnf install mesa-libGLU.x86_64

• Now download the Linux version of Davinci Resolve from https://www.blackmagicdesign.com/products/davinciresolve/
• Go to the directory where you downloaded Davinci Resolve
• Unzip: $ unzip DaVinci_Resolve_16.0b7_Linux.zip
• Install: $ sudo ./DaVinci_Resolve_16.0b7_Linux.run -i
• Launch: Activities -> Search box -> Type "Davinci"

Note: The first time that Davinci Resolve 16 is launched, the welcome screen will get stuck (it will remain white). Launch "System Monitor" and end the process "DaVinci_Resolve_Welcome". Davinci Resolve 16 will get "unstuck" and open up normally.

Blocking Nouveau

• create a new /etc/modprobe.d/ conf file with this values:

echo 'blacklist nouveau' >> /etc/modprobe.d/disable-nouveau.conf

echo 'options nouveau modeset=0' >> /etc/modprobe.d/disable-nouveau.conf

• Regenerate the kernel initramfs:

## Backup old initramfs nouveau image ##

$ sudo mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img

## Create new initramfs image ##

$ sudo dracut /boot/initramfs-$(uname -r).img $(uname -r)

• Edit /boot/grub/grubenv and rootadd rd.driver.blacklist=nouveau:

kernelopts=root=UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx ro rd.driver.blacklist=nouveau rhgb quiet

• Edit /boot/efi/EFI/fedora/grubenv and add rd.driver.blacklist=nouveau:

kernelopts=root=UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx ro rd.driver.blacklist=nouveau rhgb quiet

• Add this line in /etc/default/grub (it will also update /etc/sysconfig/grub):

GRUB_CMDLINE_LINUX="... nouveau.modeset=0 rd.driver.blacklist=nouveau"

• Update GRUB:

## BIOS ##

$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg

## UEFI ##

$ sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

If you get this error:

Generating grub configuration file ...

/usr/bin/grub2-editenv: error: environment block too small.

Log in as root and do this to fix:

# rm /boot/grub2/grubenv

# grub2-editenv /boot/grub2/grubenv create

Disable Wayland and enable Xorg as the default GNOME session

• Edit /etc/gdm/custom.conf and uncomment WaylandEnable=false.
• Optional: add the following line to the [daemon] section:

DefaultSession=gnome-xorg.desktop

• Save the custom.conf file

How to auto mount a disk on start up

Option 1. Command Line

• Find UUID partition:

$ sudo blkid

...

/dev/sdc2: LABEL="Datos" UUID="368A7A9A8A7A5679" TYPE="ntfs" PARTLABEL="Basic data partition" PARTUUID="670e8067-f3d4-44db-a493-d69e4c9e2e9e"

...

• Create a new entry in /etc/fstab:

$ sudo echo "UUID=368A7A9A8A7A5679 /run/media/cheo/Datos auto defaults 0 0" >> /etc/fstab

Option 2. Gnome Disk

• Launch Gnome Disks
• Look for the partition and follow these steps:

Troubleshooting

Fedora not booting

If the OS does not boot, restart the computer and launch the advanced Fedora options -> Rescue

Then check the booting logs:

cat /var/log/boot.log

As an example, we find this issue:

[    3.158325] dracut-pre-pivot[630]: Sep 24 22:12:52 | /etc/multipath.conf does not exist, blacklisting all devices.

[    3.158430] dracut-pre-pivot[630]: Sep 24 22:12:52 | You can run "/sbin/mpathconf --enable" to create

[    3.158539] dracut-pre-pivot[630]: Sep 24 22:12:52 | /etc/multipath.conf. See man mpathconf(8) for more details

As the logs shows, the file /etc/multipath.conf does not existes. As the logs suggests, we run /sbin/mpathconf --enable to create the file.
