Error with Intel Graphics CL_DEVICE_NOT_FOUND

[GeenRx1]

Hello everyone,
I used to render with LuxCore on windows and everything was fine.
Since I moved to Linux (Linux Mint Debian 13) it is impossible to work with LuxCore as I get the error: CL_DEVICE_NOT_FOUND
I tried all the settings to force rendering to CPU, avoiding OpenCL, but nothing.
Reinstalled / reconfigured intel drivers.

Any idea how to fix this issue?

Error detail:
OpenCL driver API error (code: -1, file:/project/src/luxrays/devices/ocldevice.cpp, line: 89): CL_DEVICE_NOT_FOUND


Blender Version: 5.0
LuxCore: v2.10

Here it is my system:
12th Gen Intel® Core™ i9-12900H
Intel® Iris® Xe Graphics

Hello,

First of all, please be aware that LuxCore v2.10 does not fully support Blender 5.0, even when the OpenCL issue is resolved.

I don't know specifically for this combination of Linux + Intel drivers, but there has been a similar situation with rusticl drivers, see the later posts in this GitHub Issue: https://github.com/LuxCoreRender/BlendL ... issues/664

Check if you can also run the command "clinfo --list" and get the same situation where there is a platform with no devices.

Thank you very much for the reply.
I tried also with other Blender versions (4.3) and I get the same error. I do not think it is an hardware issue because on Windows on the same PC it was working, also with Blender 5.
I also tried to install blender from different sources: Flathub, APT, downloaded from site. Always same error.

I will now try disabling the mesa.icd as suggested in the mentioned post.

Here it is the output of clinfo --list:
Platform #0: Intel(R) OpenCL Graphics
`-- Device #0: Intel(R) Graphics [0x46a6]
Platform #1: Intel(R) OpenCL
`-- Device #0: 12th Gen Intel(R) Core(TM) i9-12900H
Platform #2: rusticl
Platform #3: Clover
Platform #4: Portable Computing Language
`-- Device #0: cpu-haswell-12th Gen Intel(R) Core(TM) i9-12900H

Fixed!
I renamed mesa.icd and rusticl.icd appending .old
in the folder etc/OpenCL/vendors/

now it works.

Thanks!!

Good to hear it worked!
