[SOLVED] Segmentation Fault launching Davinci Resolve
I installed Davinci Resolve on RX6500XT. The opencl driver i use is opencl-mesa. I can still open DR, but i cannot open any projects. I can create new projects, but i cannot click any other tabs(edit, media, deliver, ......) after i created the new project. Heres the ~/.local/share/DaVinciResolve/logs/ResolveDebug.txt:

Signal Number = 11 # Segmentation Fault
================================dr-checker.py says that "You should uninstall opencl-mesa."
But if i use any other OpenCL driver, such as opencl-amd, rocm-opencl-runtime, it reports Segmentation Fault, and doesnt even launch. Here is the ~/.local/share/DaVinciResolve/logs/ResolveDebug.txt when I use opencl-amd or rocm-opencl-runtime:

does not work for me.
What I've Tried:
HSA overrides: HSA_OVERRIDE_GFX_VERSION=10.3.0, 10.3.1, 10.3.2, 10.3.4.
Kernel switch to LTS and zen

Re: [SOLVED] Segmentation Fault launching Davinci Resolve
Please post the contents of ~/.local/share/DaVinciResolve/logs/ResolveDebug.txt
Also the outputs of
$ lspci -k
$ pacman -Qs opencl
$ clinfo #install clinfo if neededDisliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: [SOLVED] Segmentation Fault launching Davinci Resolve
Hi, I had the exact same crash log with an RX 6700XT and in my case, I could access the different tabs (File, Edit, Trim and so on), but it would always crash after a while. After searching for hours, I finally found a way to make Davinci Resolve not crash (so far):
you have to remove opencl-mesa and install opencl-amd instead from the AUR. However, as you said previously, with opencl-amd, Davinci doesn't even start and to fix that, I had to look at the comments on the AUR page of the opencl-amd package and find the last version (1:7.2.0-1 as of today) doesn't seem to work on old card like the 6000 series or earlier and you have to revert back to 1:7.1.1-1, the last working version.
Here's how to do it:
open a terminal and clone the repo with
git clonethen do
cd opencl-amdgit checkout 42c9eb7(42c9eb7 refer to the 7.1.1 version)
makepkg -siYou can optionally add
IgnorePkg = opencl-amdin /etc/pacman.conf to not update this package the next time you update the AUR.
Hope this works for you

This fixed the issue. Thanks.
Also, opencl-mesa must be uninstalled to run DR, otherwise it will still crash.

Re: [SOLVED] Segmentation Fault launching Davinci Resolve
It's important to note that it's probably not a problem with ROCm or opencl-amd. There is a post about Linux in the Davinci Resolve forum: https://forum.blackmagicdesign.com/view … ilit=linux
I don't have it installed personally to test. And I don't think I want to install all of its dependencies either. Maybe if I find time I can try to install it in a flatpak.

Honestly, I'm not even surprised... Corporations will always only support the most popular thing, leaving the rest in the dirt and provide the bare minimum in updates/features, even if the only thing they have to do is click a button, having to do the rest yourself to keep up by patching things here and there, even on Windows or MacOS. At least, Davinci has a Linux port, so there's that...
And concerning the flatpak: they unfortunately don't package it themselves (though they should). Now I saw it was possible to package it yourself, but it looked horrible to do and very bothersome considering you can't automate the download of the Davinci Resolve package anymore from their website as you have to fill a sort of registration form now. But you could create a script that would automate that I suppose (?).
