@sft To see what’s installed use zypper se -i intel it may be there but install the other tools mentioned by inxi eg zypper se --provides eglinfo and if not installed, install the package.
So you have a Gen-9 device so GUC2, so could either add to grub with i915.enable_guc=2 it will taint the kernel, but worth a try after checking above first.
You can check for eample with;
journalctl -b --no-hostname | grep -E "guc|huc"

journalctl -b --no-hostname | grep -E "guc|huc"
