Install nvidia and CUDA

Installing CUDA drivers (nvidia drivers will be also installed)

https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html

Note that we are not installing the NVIDIA CUDA Toolkit. We are installing just the CUDA drivers.

• Install gcc

$ sudo zypper in gcc

• Install development packages. They must be the same version as the kernel headers. Do this:

$ uname -r

4.12.14-lp151.28.10-default

The version is 4.12.14-lp151.28.10 and the variant is default. The kernel headers and development packages can then be installed with the following command:

zypper install kernel-<variant>-devel=<version>, which in the above example would be:

$ sudo zypper in kernel-default-devel=4.12.14-lp151.28.10

• Download the NVIDIA CUDA Toolkit (in this guide, I'm using the rpm package)

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=OpenSUSE&target_version=150

• Verify download

http://developer.nvidia.com/cuda-downloads/checksums

$ md5sum <file>

• Install CUDA driver

$ sudo rpm --install cuda-repo-<distro>-<version>.<architecture>.rpm

$ sudo zypper refresh

$ sudo zypper in cuda-drivers

$ sudo usermod -a -G video <username>

• Reboot
• Package upgrade. When a new version is available, use the following commands to upgrade the driver:

$ sudo zypper in cuda-drivers

• Remove CUDA

$ sudo zypper remove "*cublas*" "cuda*"

• To remove NVIDIA Drivers:

$ sudo zypper remove "*nvidia*" 

Installing nvidia drivers (in you don't want to install CUDA)

https://en.opensuse.org/SDB:NVIDIA

• Add nvidia repository (for openSUSE Leap 15.1):

$ sudo zypper ar -f http://download.nvidia.com/opensuse/leap/15.1/ nvidia

• Install nvidia driver (first command is for v390 and second command for v430

$ sudo zypper in x11-video-nvidiaG04

$ sudo zypper in x11-video-nvidiaG05

• Add your user to video group. Otherwise 3D acceleration won't work

$ sudo usermod -a -G video <username>

• Reboot

Uninstalling the NVIDIA drivers

1. Start YaST, go to: Software -> Software Management
2. Change the 'Filter' to filter by software repositories
3. Select the respective NVIDIA repository
4. Mark any installed package from this repository for deletion and press 'Accept'. You may be prompted for conflicts, please ignore any conflicts and chose to break dependencies.
5. Now in YaST select: Software -> Software Repositories
6. Chose the respective NVIDIA repository and mark it 'disabled' - don't delete it as it will return enabled the next time the repositories are synced with the server.

Uninstalling the proprietary drivers will restore the previous X configuration file /etc/X11/xorg.conf if one existed. If the hardware has changed in the mean time it may be necessary to manually edit this file.

On Leap 42.3 you may want to install the drm-kmp-default package again.

$ sudo zypper in drm-kmp-default

Install Davinci Resolve 16

• Download the Linux version of Davinci Resolve from https://www.blackmagicdesign.com/products/davinciresolve/
• 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 black). You have to end the "DaVinci_Resolve_Welcome" process within "System Monitor". Launching Davinci Resolve 16 after this will be fine.
