Unfortunately, Resolve still does not start.

I used the kernel arguments mentioned by Walter.
My card is a Radeon RX 570.

OpenCL != OpenGL

Besides the right driver requirements "Radeon vs AMDGPU (both opensource)" I mentioned the closed source other TWO components: OpenGL and OpenCL. The first, OpenGL can be taken care off by "Mesa" which is the default for most linux distributions and did work until Davinci Resolve 16.0 but it must be replaced with closed source proprietary OpenGL (if you use the amdgpu pro driver) which is a requirment for Davince Resolve 16.1 and higher.

The kernel arguments I gave are for early GCN AMDGPU's lower than Rx4xx series like R9-290x or R9-390x (which uses by default RADEON driver) and you have RX570 (default AMDGPU driver). The later AMDGPU driver can be assisted with closed source OpenCL modules or replaced OpenGL modules(only one OpenGL system can be installed). For Vulkan and OpenCL multiple backends can be installed and used with AMDGPU on the same system.

You already answered one of my question, that is you are running with a RX5xx card with only OpenCL provided by AMDGPU pro driver (pal/orca/legacy) and still cannot run current Resolve 16.xx because you probably miss the AMDGPU pro OpenGL driver... so for confirmation?

@Andreas56
Please try the older first 16.00 release of Davinci resolve and see if that works with only having OpenCL installed, or install the proprietary closed AMDGPU pro OpenGL component which (removes Mesa OpenGL) but you have to find the archlinux/manjora equivalent package:https://aur.archlinux.org/packages/amdgpu-pro-libgl/

Hi Walter,

I tried the proprietary OpenGL driver and Resolve still does not start. Here is the log.

Now, as you suggested, I downgraded to Resolve 16.0 and removed the proprietary OpenGL driver. That still did not help. I also tried old Resolve 16.0 + proprietary OpenGL and that caused the same error as in the log above.

All three variants with proprietary OpenCL.

@Andreas56

You are sure Mesa OpenGL was also removed/setup functioning correctly when switching to/from AMDGPU Proprietary legacy OpenGL?

Something on my system got updated and now I can neither run Davinci or the installer. I had a working Resolve Studio 12.6.3 installation working fine. I'm not sure what got updated but today I could no longer launch the program.

I tried downloading 12.6.6 but could not launch the installer.

I realized both the app and the installer run "genconfig", this is segfaulting on `libqxcb.so` which is part of Qt5's `libqt5gui5` package. I updated this package from 15.12.5 to the latest 15.4.2 but am getting the same segfault.

Anyone else seeing this? Is there a way to work around genconfig?

Here is the gdb backtrace:

I'm running Resolve 16.1 on Ubuntu 19.10 with old ROCM OpenCL drivers because previously the AMDGPUPRO drivers didn't work with Fusion. While these older ROCM drivers do work with Fusion, they are very buggy in the color grading tab - often causing program crashes doing the simplest things.

Question: Is AMDGPUPRO 20.30 + AMD OpenCL libs finally working with Resolve? If I upgrade to Ubuntu 20.04 and install the latest AMDGPU is this known to work? Will I have to wipe everything and install a suppoerted CENTOS?

I'm even thinking of installing Windows just to keep Resolve functional. But I'd much rather run Linux.

Am a licensed Resolve Studio owner, if that matters.

My Operating System is Manjaro (Gnome) and while it appears that I was able to install the AUR package of DaVinci Resolve through yay, it crashes while loading. In the loading screen, it says "Looking for Control Surface".

https://files.catbox.moe/gw0hos.png

I believe it's talking about one of these: https://files.catbox.moe/jk1jcd.png
It has worked fine on Windows 10, so this piece of Hardware is not essential. The software does not seem to be available on other outlets such as snap, flatpak. Is there an additional package I can install that will fix this?

Thu Sep 10, 2020 5:50 pm

I've succesfully installed Resolve 16.2.6 in my Ubuntu 20.04 with Radeon RX480 according to this youtube video tutorial installation process titled: "Installing AMD OpenCL ROCm driver Ubuntu 20.04"

I have this only one issue: I don't see nothing on the video preview window ( Cut and Edit ) otherwise I can see the video preview window on the Color tab.

Interresting to see that with only the OpenCL supplement from ROCm(instead of the AMDGPU pro OpenCL), you we're able to start Davinci resolve. Could you check if you really run OpenGL from Mesa and not AMDGPU pro propietary legacy OpenGL, because that also seem to be a requirement since DR 16.1 or higher?

Please run the following command in the terminal and post the output:

Code: Select all: glxinfo | grep Mesa

Have you also tried installing only the AMDGPU OpenCL drivers and see if that worked?

If you have enough RAM, you may just try ubuntu 20.04.1 from USB live RAM session and test if Fusion Tab/Page is working for you?

I haven't tested Fusion part but in 20.04.1 with AMDGPU pro (OpenGL & OpenCL) install DR 16.2.x was playing 4k&6k braw examples fine including intensity-pro output (DesktopVideo 11.6.0 driver).

Here is my: glxinfo output:

OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.1.7 - kisak-mesa PPA
OpenGL version string: 4.6 (Compatibility Profile) Mesa 20.1.7 - kisak-mesa PPA
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.1.7 - kisak-mesa PPA

AMDGPU OpenCL drivers doen't worked for me at all, in fact I don't recommend AMDGPU drivers for any use, games, 3D apps, etc.

Again very interesting to see you have replaced the default Mesa stack with kisak-mesa PPA. This may indeed fix the AMDGPU propieraty OpenGL requirement for Davinci Resolve 16.1 & higher, still have to test/confirm that.

Did you also replace more default graphics/xorg or kernel related modules with other PPA's, because that may be the reason the default Ubuntu 20.04 amdgpu kernel driver did not work with the default AMDGPU 20.04 proprietary driver (OpenGL & OpenCL components)?

According to the Rocm installation website, I summarize the steps to install the opencl drivers:

Code: Select all: sudo apt update sudo apt install libnuma-dev libncurses5 sudo reboot wget -q -O - http://repo.radeon.com/rocm/rocm.gpg.key | sudo apt-key add - echo 'deb [arch=amd64] http://repo.radeon.com/rocm/apt/debian/ xenial main' | sudo tee /etc/apt/sources.list.d/rocm.list sudo apt update sudo apt install rocm-dkms && sudo reboot sudo usermod -a -G video $LOGNAME sudo usermod -a -G render $LOGNAME echo 'export PATH=$PATH:/opt/rocm/bin:/opt/rocm/profiler/bin:/opt/rocm/opencl/bin' | sudo tee -a /etc/profile.d/rocm.sh

For testing de correct rocm opencl installation type:

Code: Select all: rocminfo clinfo

For Davinci Resolve 16.2.6 installation I used the original DaVinci_Resolve_Studio_16.2.6_Linux.run, thats it, no makeresolvedeb or whatethever

About kisak-mesa, I've installed this drivers to be able to play Steam games with the proton launcher (steamplay), for certain games it's needed, but I think that with the original mesa drivers that come in ubuntu 20.04, everything would work the same way.

Hello,
I posted a thread yesterday but maybe if I write here it makes more sense. I am migrating form Macbook Pro to a new PC for editing and I'm considering Linux.
I wonder if someone here can give some feedback on running DR on Linux for professional editing, if it's more or less the same of other OS or still lacking, because I've seen a lot have been changed since the start of this thread.
What distro would be better, considering I'm devoting this PC to video editing on DR?
If you also can provide a link to some installing tutorial or procedure it would be very appreciated as well.
I hope this was the right place to ask this questions, couldn't find a more specific thread, maybe DR/linux users are not so many, so many thanks to anyone can help or just give some info about it, cheers:)!

Sat Sep 26, 2020 11:21 am

Hi,

if you want a dedicated Linux-PC for editing I'd consider using CentOS as provided by Blackmagic Design - installation is also available from Blackmagic Design. If instead you like to have a general purpose Linux Box then you might consider a more popular distribution like Ubuntu or Linux Mint. I am using Resolve Studio on Linux Mint and did not have any problems whatsoever. It also depends on your hardware - you should avoid AMD graphic cards and use Nvidia instead because Resolve is using CUDA and that's only available on Nvidia cards. If you don't have Nvidia you will rely on OpenCL which is way slower than CUDA.

Blackmagic Dsign also has a list of minimum system requirements on their web site.

It's all a matter of a good balance between hardware and software.

Sat Sep 26, 2020 12:16 pm

Hi,
pretty much what Dieter said

also, please do bear in mind that on Linux you have limitations on the supported codecs, especially audio codecs: you cannot import AAC and MP3 on both free and Studio, h26x export is available only on Studio with Nvidia GPUs.
Not a real problem since material can be easily transcoded to be ingested with ffmpeg and other free and open source tools easily available on Linux.

Sun Sep 27, 2020 8:56 am

I will have an NVIDIA card, still building it... I guess that I will continue to use macbook for browsing and simple stuff and using the PC mainly for editing, though linux looks very beautiful to me. Now I find Centos a little intimidating and server oriented, so, since I see that there are Debian users, I will probably go there. Your experience with Mint is encouraging, thank you very much!

Sun Sep 27, 2020 10:04 am

You're welcome

Have fun.

You are sure Mesa OpenGL was also removed/setup functioning correctly when switching to/from AMDGPU Proprietary legacy OpenGL?

@Walter Sonius
Yes. I additionally tried a method recommended in the Arch Wiki to use specific drivers for a single application, so yeah, no Mesa for Resolve. Still the same error.

Hi All, I tried a few years ago and gave up, but now I really wanna try again

so : I can install davinci resolve well on my machine via the makeresolve .deb , version 16.2.1 , starting is fine, then it wont find CUDA and will be running with open GL , and when loading video files, no matter what file format: I can see the thumbnail for a bit, then it greys out and it wont play any more.. any suggestions?

I got Resolve to launch using Mesa OpenGL, and just the amdocl64 part from AMDGPU-PRO. Color grading seems to work, transitions work (including fusion ones). The issue was one OpenCL extension misbehaving (particularly, clGetGLContextInfoKHR), so I blacklisted it using LD_PRELOAD trick, and all the code for it can be found on my GitHub repo (h33p/resolve-amdocl-fix).

Alternatively, try this GDB script:

Code: Select all: set breakpoint pending on b clGetGLContextInfoKHR run p $device_ptr = (unsigned long*)$rcx finish p *$device_ptr = 0 p $rax = -30 c

So it seems that Resolve (Studio) 16.2.7, when having been turned into a .deb archive with makeresolvedeb, no longer runs on Debian 10/stable with working CUDA because it requires a newer Nvidia driver.

Does anyone have experience with 16.2.7 under Debian testing (where newer Nvidia CUDA drivers are provided)?

Yes, I have the same experience. 16.2.7 no longer runs on Debian 10 since the NVIDIA driver is too old. It does however work very well under Debian bullseye/sid that comes with NVIDIA driver 450.66.

Wed Oct 14, 2020 11:01 pm

first of all thanks for all the helpful info that is posted here!
I've read through this thread (and a couple more) which helped me in getting a better idea of my problem but unfortately not really coming to a solution. I succesfully installed Resolve 16.2.7 on a Debian 10 machine (Intel CPU, Nvidia GPU) via makeresolvedeb. I had installed the adequate Nvidia 450.66 driver beforehand via buster backports and it seemd to work fine (Nvidia X Server Settings App works and the card works fine in Blender as well).
I do have the GPU settings set to discrete in BIOS and run the system solely on the nvidia card (Quadro T2000).

When I try to run Resolve, it crashes, what seems to be due to missing OpenCL drivers.
Also clinfo command in terminal returns with: "0" which seems to be the issue..?

I was tempted to install nvidia-libopencl1 via synaptic but since this would automatically remove lots of my CUDA libraries i did not dare to do so (as I honestly still do not really understand why I need the OpenCL Framework if Resolve is anyway using CUDA? missing knowledge here..).

I would be grateful for any support or ideas. Thanks again to Daniel Tufvesson and others for providing easier access for this software on open source platforms and sharing their skills and knowledge with the lesser linux and command-line-experienced individuals like me.

Hi Richard, welcome to the forum!

If you hold down ctrl+, ("control" + "comma") when you start Resolve you should be able to reach the configuration menu. Look under "Memory and GPU" -> "GPU configuration". Can you see your GPU there? It looks like there is something wrong with the driver installation. In your case Resolve should be using CUDA and not even mention OpenCL in the log.

: Screenshot_select-area_20201015164159.png (38 KiB) Viewed 1463 times

Which version of libcuda do you have installed? This is how it looks in Debian 11 (should be relatively close to the Debian 10 backport)

Code: Select all: $ dpkg -l | grep libcuda ii libcuda1:amd64 450.66-1 amd64 NVIDIA CUDA Driver Library

Thu Oct 15, 2020 3:27 pm

Thanks Daniel! I am able to reach the settings screen even without ctrl+ after Resolve let me know it was unable to find OpenCL. I can then also choose GPU Config: CUDA -> manual -> Quadro T2000. But shortly after clicking Save the program crashes. Alternatively I could choose a Storage Folder and crashes directly after that without even accessing the GPU config.

The log file does not seem to give any further hints, but maybe I am missing something:
https://paste.debian.net/1167311/

dpkg -l | grep libcuda returns:

$ dpkg -l | grep libcuda
ii libcuda1:amd64 450.66-1~bpo10+1 amd64 NVIDIA CUDA Driver Library

ii libcudart10.1:amd64 10.1.243-6~bpo10+1 amd64 NVIDIA CUDA Runtime Library

could it be that that the 2 driver libraries amd64 and:i386 conflict while starting Resolve?

Fri Oct 16, 2020 9:28 am

So I managed to get Resolve 16.2.7 working on Debian 10. I'm not sure if documenting my way of resolving the issue will be much help to others as I have the impression the issues might have been related to my specific setup (Debian 10 stable with a newer kernel due to specific hardware driver necessities) but here we go:

As mentioned, I had installed the 450.66 nvidia driver via backports stable. The installation went well but for some reason did not install any OpenCL ICD Profile (which appears to be needed by resolve, even though it's really crunching the numbers later with CUDA). It did install the nvidia cuda toolkit and using the GPU with Blender was working fine.
Trying to install the OpenCL ICD afterwards was not possible as it conflicted with some of the CUDA libraries (of the same 450.66 driver version) which I did not dare to remove.

I purged the whole nvidia drivers and reinstalled v 455.60 again via backports. This time, funny enough, the install left out even more libraries, not installing any OpenCL ICD but also not installing the CUDA toolkit. So I was running an xserver on my GPU but none of my programs were able to access it. But contrary to the previous situation I now could install the OpenCL icd (nvidia-openCL-icd) without any package conflicts. For people using synaptic: you can choose to install the newer version from backports via: Package -> Force Version. After doing this, Resolve started flawlessly.

I did some test renders and everything incl. GPU Scopes looks good so far. While I like to have a professional feature set, my NLE work is generally directed towards classic AB editing. So I am seldom in need of the more complex functionalities or very demanding grades, therefore can't tell you, if each and every function is working as good as it should.
If anybody wants me to test out something on the system I'd be happy to do it, just let me know (keep in mind at the moment I am not running the studio version).

Thanks to Daniel and others for sharing their thoughts and ideas on the issue!

Wed Oct 21, 2020 6:25 am

Can anyone please help me figure out what's going on here with the seg fault on Linux? I have gone through a linux re-install and 4 nvidia driver versions and still no dice. I've never been able to run davinci successfully

I get a completely black (or white, depending on nvidia driver) window appear the very first time running `/opt/resolve/bin/resolve`

This same thing happens every time I remove `~/.local/share/DaVinciResolve/` ^^^

I get the same blank window when running `/opt/resolve/Onboarding/DaVinci_Resolve_Welcome` manually, with a whole bunch of errors like: `qt.network.ssl: QSslSocket: cannot call unresolved function BLAH`

After I kill that initial welcome message, and try to run resolve again with `/opt/resolve/bin/resolve` I get a segfault like this:

Am I missing something like that DeckLink library?

Sorry for posting I've tried so many things and really have no idea what I'm missing, hopefully it's something simple.

so, returing back with a little update.
I've upgraded to the studio version for the convience of directly importing the occasional h.264 file among other things.
The system is running smooth so far, but there are two issues I've come across and would be interested if this happened to anybody else using the studio version on Linux:

Issue Nr.1: I do not find any h.264 export options on the deliver page. this seems weird as I can import h.264 just fine now and, judging from da vincis codec pdf lists, was under the impression I should be able to also export to h.264 with the studio version on Linux, right?
Also, using the Quick Export Option, Resolve puts loads of dpx files (1 per frame) into specified the output folder instead of a h.264 file.
The ffmpeg codecs are for sure on my system but I suppose Resolve should be using its proprietary codecs anyway?

Issue Nr.2: I am unable to export files with an alpha channel. Alpha output is set and the node is connected. Nevermind Cineform or DNxHR, both with "Individual Clips" and "Export Alpha" selected, Resolve always renders out the file with a black background.

Anybody with any ideas on this?

Can be done, with certain Nvidia GPUs (NVENC for encoding).

Your Quadro T2000 (laptop GPU?) is a bit skimpy for Resolve. You may also experience weird glitches like the alpha channel export, sorry to say.

Thanks Sulo for your input. I was afraid that it had to do with GPU compatibility but was unable to find an actual list of compatible cards. Still not sure if that's really the only reason as the T2000, while it surely is not a power house, does actually support NVENC de- and encoding. And I thought 4GB memory, while certainly not being a lot by today's standards, should suffice for encoding these formats.
but yeah, maybe it's really still just a compatibility issue.

Alpha export works now btw leaving this -so far- the only issue as everything else works quite smoothly (surprisingly even without using proxies or optimized media yet...)

Sorry, forgot to add.

Here's Rohit from BMD.

Rohit Gupta wrote:The GPU also needs more than 3.5GB of VRAM to do HW accelerated encode... This is a Resolve imposed restriction. If we use up too much VRAM for h265 encoding, then you will have problems with Resolve processing.

Easy way out would be to export as DNx and use Handbrake for h264/5 encoding.

thanks for the heads up!
yes, i do usually use Handbrake or my very limited bash knowledge for ffmpeg transcoding and since I am not in a position where I have to transcode/deliver lots of material every day, this little extra step is not really a big issue.
and just to share it: apart from handbrake there's a also new open source ffmpeg gui frontend in development right now from rainbox laboratories called "DuME" which is currently in alpha still but is working fine on my machine for different transcoding tasks (but has no batch functionality yet).

after a little more research I found the problem: the NVENC library (libnvidia-encode1) was not installed. It simply failed to install during regular driver setup (see issues above..). Installed it now manually and h264 and h265 options are now showing and, judging from a quick test, seem to be working well.

I am having the same problems after upgrading from Debian 10 stable/Buster to Debian 11 testing/Bullseye: Resolve 16.2.7-1 (installed via makeresolvedeb) complains that there is no CUDA on the system and no longer works.

libnvidia-encode1 is installed, as is nvidia-cuda-toolkit, all from the Debian testing repository, with driver version 450.80.02, and the Nvidia kernel modules (via nvidia-kernel-dkms) have been successfully built and installed.

What can one do in such a situation?

450.80 was released to bullseye/testing just a day or two ago. I would expect there to be bugs or compatibility issues. Can you provide the Resolve logs?

Thanks so much for looking into this!

Here is the log:

It looks like you do not have a working OpenCL. Even though you use CUDA you still need a working OpenCL setup. Do you have nvidia-opencl-icd installed?

Hmm. No obvious problem there. Do you perhaps have multiple OpenCL ICD installed? This can be verified by looking in the directory /etc/OpenCL/vendors/. There should be one and only one *.icd file there. For NVIDIA it will be called nvidia.icd.

If that looks good then run "clinfo" and post the result here.

There is the contradiction:
/etc/OpenCL/vendors only includes nvidia.icd

...but clinfo gives "Number of platforms 0"

I also ran Darktable's OpenCL test (darktable-cltest) and it outputs that the runtime libOpenCL has been found, but that no platform is available and that OpenCL is not available on the system.

Thanks again for all your help!

Now I found the solution with help from the Debian User forum - and it's highly relevant to everyone running Resolve on Debian testing/Bullseye at this moment:

"The main nvidia module will work with kernel 5.9. However, the nvidia-uvm module will not. The upshot is that those that need CUDA and CUDA-based functions (like NVDEC/NVENC) should keep a 5.8 kernel handy until Nvidia releases a driver that works around the GPL symbol issue."

My workaround was to install Kernel 5.8 from the Debian Buster/stable backports repository - and voilà, CUDA, OpenCL and Resolve work again!

Question on AMDGPU-Pro w/Ubuntu 20.04.1 and Resolve Studio. Noticing the GPU fan isn't spinning up during load, which forces an overheat system shutdown. But the fan spins on powerup and definitely blows. This is w/ an AMD TR1950x w/ VEGA FE card. Resolve itself works in this setup. Until you put the machine under load.

Davinci Resolve 17beta does start on ubuntu 20.04 with default mesa opengl, default amdgpu drivers plus amdgpu-pro opencl on a dated r390x. However as soon as opening a new project and filling the timeline with a 6k braw example clip it crashes.

Still have to test amdgpu-pro legacy opengl which was a requirment in the past.

Ok i run Davinci Resolve on manjaro sucessfully. I can start ist and work.
But if i install the studio version using the installer "DaVinci_Resolve_Studio_16.2.7_Linux.run" overwriting the normal version, i can NOT start it anymore!
It is stuck forever on CHECKING LICENSE. To confirm the dongle is NOT broken i used it on a windows machine and it works.
I am trying to debug this for 10 hours now, the whole day.

The crash log says:

Code: Select all: #TIME Thu Nov 12 21:01:08 2020 - Uptime 00:02:40 (hh:mm:ss) #PROGRAM_NAME DaVinci Resolve Studio v16.2.7.010 (Linux/Clang) ./resolve() [0x557b519] ./resolve() [0x557ad0a] /usr/lib/libpthread.so.0(+0x140f0) [0x7f7d054860f0] /usr/lib/libc.so.6(__select+0x6b) [0x7f7d02f17b7b] /opt/resolve/bin/../libs/libQt5Core.so.5(+0x24ca95) [0x7f7d1a372a95] /opt/resolve/bin/../libs/libQt5Core.so.5(+0x9c7c0) [0x7f7d1a1c27c0] /usr/lib/libpthread.so.0(+0x93e9) [0x7f7d0547b3e9] /usr/lib/libc.so.6(clone+0x43) [0x7f7d02f20293] Signal Number = 1

I have blacklisted the nouveau driver using a custom file in /etc/modprobe.d too
I have installed all nvidia drivers and cuda. As i said the normal "non studio" version works.
I get the loading screen and then CHECKING LICENSES will stay there forever.

Ok the problem is not my OS or any drivers.
The soultion is ... there was an USB Hub connected to an USB Port. I removed it and it works. Holy...crap.
Logical because the normal non-studio was running.

Anyone had this issue too? I cant move my window. I am on Ubuntu 18.04, GTX1080Ti and Resolve version 17.0B Build 9

Hello,
I found in the history of this thread this message. I have probably very similar issue. I've checked the stack trace, and it's almost the same.
I face this issue during Resolve startup.

This issue was described one and half year ago. The difference between this issue and my:
[*] I'm trying to run Resolve on Centos 8 - above issue was related to Ubuntu
[*] I'm trying to run Resolve 17 (I also tried on 16.2.7.010 with similar stack trace) - above issue is related to Resolve 15

The discussion on this thread was focused on Ubuntu, I didn't find / missed the solution there.

One issue I know is the version of nvidia driver (I installed it with success). My version is: 390 when recommended one is 450. - Is it an issue in that case when crash happens during FairlightPage loading?

Any idea?

Best regards

FYI, my (quite positive) experience of DR 16.2.7 on Ubuntu 20.04.1 with AMDGPU-PRO 20.40: viewtopic.php?f=21&t=127060.

Why do you use the ancient driver version?

Just install the latest and greatest driver 450.80.02 or higher (for instance from the graphic driver PPA) and be done with it. It is not only recommended - it is mandatory.

PS:

Would be nice if people could put lenghty logs into code tags - that would make the thread more read-friendly.

Would be nice if people could put lenghty logs into code tags - that would make the thread more read-friendly.

Hello,
I'm using DR on my laptop, but I want to move to stronger machine. So I've taken my old PC and I'm trying to install DR on Linux. If everything will be working fine I want to buy some hardware according to my needs and budget

. But I don't want to by new workstation as long as I'm sure I can install DR on Linux.

I tried to install 450 driver but during the installation I had a message that my card is not supported by 450 driver and I should install 390. It is strange because GeForce GT 730 is included in on the list of supported hardware by the 450 driver.
I'll try to install it once again. Maybe I missed sth.

(sorry for previous bad formatting)
