Solusi
Pilih sesuai dengan apa yang tidak ada (missing) pada keterangan galat di atas
Salin berkas *.bin ke /lib/firmware/i915
Keterangan:
The download files are now called firmware blobs which is new-speak for firmware drivers. It stands for Binary Large OBject (BLOB).
Drivers are sorted by processor:
  • bxt Broxton, Canceled in 2016, successor to Cherry Trail processors
  • kbl Kabylake, 7th generation, eg i7-7700
  • skl Skylake, 6th generation, eg i7-6700
Then drivers are organized by subgroup (full explanation here):
  • GUC - GuC is designed to perform graphics workload scheduling on the various graphics parallel engines.
  • DMC - DMC provides additional graphics low-power idle states.
  • HUC - HuC is designed to offload some of the media functions from the CPU to GPU.
