My LUKS password wouldn't work at all for an unknown reason and no WiFi device. I reinstalled Ubuntu 19.10 with no LUKS and reran the above drm-tip install. Still no WiFi and still no dual DP monitors. See below. stuart@SSH-NUC:~/drm-tip$ sudo cat /sys/kernel/debug/dri/0/i915_dmc_info fw loaded: no path: i915/kbl_dmc_ver1_04.bin program base: 0xfffffdfe ssp base: 0x00000000 htp: 0x00000000 stuart@SSH-NUC:~/drm-tip$ dmesg | grep i915 [ 0.415019] i915 0000:00:02.0: Found 64MB of eDRAM [ 0.415071] i915 0000:00:02.0: vgaarb: deactivate vga console [ 0.419134] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem [ 0.419167] i915 0000:00:02.0: Direct firmware load for i915/kbl_dmc_ver1_04.bin failed with error -2 [ 0.419168] i915 0000:00:02.0: Failed to load DMC firmware i915/kbl_dmc_ver1_04.bin.
