Hi,
I'm using an HTPC with an i7 4650U, and get some weird hashing/banding pattern once the system has booted. I see the same issue with the 10 stable build (LibreELEC-Generic.x86_64-10.0.4.img.gz) and both 11 beta builds (LibreELEC-Generic-legacy.x86_64-10.95.1.img.gz and LibreELEC-Generic.x86_64-10.95.1.img.gz).
In order to debug, I tried a clean install of Ubuntu 22.04 and saw the same issue despite drivers being listed correctly (i915) through lspci. After reading the intel documentation at https://dgpu-docs.intel.com/installation-g…-jammy-arc.html I followed the instructions. Once all the required software was installed (but NOT the DKMS modules), I still saw the same issue. After installing the DKMS modules however, the issue was resolved.
Thinking then that I had a solution, I returned to the LibreELEC 10 stable build and used the docker addon via ssh to build the firmware files for the running kernel (which completely successfully) using the instructions here: https://github.com/intel/media-de…el-gpu-dkms.rst
I then copied the generated firmware files to the /storage/.config/firmware directory and rebooted, expecting that the appropriate firmware would now be used and my graphics would be functional again - unfortunately, this was not the case.
So, my question is: what am I missing here? I don't mind getting my hands dirty and doing a custom build if required, but it feels like there's a way to do this that I'm just not getting.
Apologies if this is an obvious question - I've tried reading the libreELEC docs to find a solution, but perhaps due to my inexperience with this type of system I can't find anything helpful.
Any help would be greatly appreciated!
