LuxCore didt see OpenCL devices on Linux
Prompt in what there can be a problem, LuxCore with openCL does not see OpenCL devices. Installed the latest driver for NVidia Cuda and OpenCL installed with it.
Re: LuxCore didt see OpenCL devices on Linux
Are you sure the installation is correct and works ? Try to run LuxMark and check if it sees the devices.

Re: LuxCore didt see OpenCL devices on Linux
You don't have a working OpenCL installation. Something may have gone wrong when you installed your GPU driver or you may have some kind of conflict between different installed packages. You can try to look for some information about you vendor driver and your Linux distribution combo. GPU vendors usually support only a very small number of specific Linux distributions.Floke wrote: ↑Fri Apr 13, 2018 12:40 pm Thanks! Here output when I try to run it

Linux is quite a mess under this point of view.

It's working for me... Nvidia 1060 Linux Mint.
Re: LuxCore didt see OpenCL devices on Linux
I had a random issue like this recently where my OpenCL device couldn't be found by Blender/Cycles or LuxCore. Just randomly stopped, and the only way to fix it was to reboot. Everything shows that it is installed, and the appropriate stuff is blacklisted, so I don't know what happened, but did notice it was happening after a system suspend, however, it hasn't happened since. Maybe a recent update threw something off. I'm on Mint 18.3.

Re: LuxCore didt see OpenCL devices on Linux
Hi, have the same problem with HD 4000 series on Kubuntu, GTX 760.
Luxmark 3.1 show both devices, LuxCore beta 3 does not.
HD 4400 is not bad, in earlier tests it was on par with GTX 750Ti in Luxmark
Cheers, mib.

Re: LuxCore didt see OpenCL devices on Linux
For the same problem, do you mean you don't see any device in LuxCore or are you missing only the HD4000 ?mib2berlin wrote: ↑Wed Apr 18, 2018 9:21 am Hi, have the same problem with HD 4000 series on Kubuntu, GTX 760.

You have installed both Intel GPU and NVIDIA OpenCL drivers and they both work with LuxMark ? It is not easy, I know because I have both AMD and NVIDIA OpenCL on my Linux and sometime one tries to delete the other
