Hi @ukasz,

Thank you for creating this contribution.

Could you please share more information about your environment, especially the kernel version? As a first step, Lunar Lake, based on the documentation, needs at least kernel 6.11:

PCI IDs	Name	Architecture	Codename	Kernel
64A0	Intel® Arc® Graphics	Xe2	Lunar Lake	6.11
6420	Intel® Graphics	Xe2	Lunar Lake	6.11

• https://dgpu-docs.intel.com/devices/hardware-table.html

Otherwise the xeKMD module will not be loaded and in dmesg you will see:

[    5.729741] xe 0000:00:02.0: Your graphics device 64a0 is not officially supported
               by xe driver in this kernel version. To force Xe probe,
               use xe.force_probe='64a0' and i915.force_probe='!64a0'
               module parameters or CONFIG_DRM_XE_FORCE_PROBE='64a0' and
               CONFIG_DRM_I915_FORCE_PROBE='!64a0' configuration options.

If you are using the recommended kernel and still experiencing some troubles, then please share a strace log from clinfo.

Thank you again for your cooperation.

Xe module is loaded correctly, i don't see anything suspicious in dmesg, below are more details on my platform:

After all I managed to "fix" it by installing packages listed below, from Intel's repository, but it doesn't change the fact that official Ubuntu packages are broken (or have insufficient dependencies), which affects thousands of users.

intel-igc-core-2_2.28.4+20760_amd64.deb
intel-igc-opencl-2_2.28.4+20760_amd64.deb
intel-ocloc_26.05.37020.3-0_amd64.deb
intel-ocloc-dbgsym_26.05.37020.3-0_amd64.ddeb
intel-opencl-icd_26.05.37020.3-0_amd64.deb
intel-opencl-icd-dbgsym_26.05.37020.3-0_amd64.ddeb
libigdgmm12_22.9.0_amd64.deb
libze-intel-gpu1_26.05.37020.3-0_amd64.deb
libze-intel-gpu1-dbgsym_26.05.37020.3-0_amd64.dde

A week ago I also tried a similar thing with Panther lake X7 358H, with the very same result.

The way to reproduce this issue is to install fresh ubuntu 24.04 on LNL or PTL and then run "apt get intel-opencl-icd clinfo", all the dependencies should be resolved by just that.

Hi @ukasz,

Thank you for the logs.

Currently, the recommended and supported method for installing GPU .deb packages on Ubuntu 24.04 (Lunar Lake) is via the Intel PPA, as outlined in the official documentation, or by using the pre-built .deb packages available from the releases page.

Please refer to the following resources:
