Hm, 760 is shown, HD 4400 only in Luxmark not in the addon. If Luxmark render on the HD 4400 Luxcore should work too, doesn't it?
Thanks for watching, mib

Yes, you should have command named "clinfo", can you post the output here ?

I don´t have clinfo but another tool check_opencl, output is:
If I try to compile clinfo it errors out CL.h is missing and I think this is a problem.

It seams it is only CPU installed, where I get GPU driver?

Ok, this make sense, I think BlendLuxCore shows only GPUs device (because they are now the only type of useful devices thanks to hybrid rendering) while LuxMark show every type of device.
I'm not sure but some time ago, Intel OpenCL for HD4000 was available only under Windows

IIRC the test I made was on WIndows, haha.
It is not important to me, thank you for the help.
May in the future they support iGPU too.
Cheers, mib

Guys I finally found solution for fedora systems and Nvidia cards! For OpenCL luxcore just needed to remove some files from "etc/OpenCL/vendors" directory. Only nvidia.icd must stay here and luxcore OpenCl start working!
Удачи всем!
