Comment # 2
on bug 107855
from Pontus Gråskæg
It doesn't appear to solve it. Instead I get a different problem earlier in the boot sequence, so it does not appear to reach the VCE code - dmesg extract below. The effect on me is that I don't get a visible prompt for my LUKS password, but if I type it in blind, _eventually_ the laptop display (and only the laptop display) shows an X-windows login. This behaviour occurs with *both* the kernel command line having amdgpu.dc=1 *AND* amdgpu.dc=0 - in other words the old radeon driver is also having problems here. The key point might be [ 2.619673] gfx7: Failed to load firmware "amdgpu/kaveri_pfp.bin" [ 2.619798] [drm:gfx_v7_0_sw_init [amdgpu]] *ERROR* Failed to load gfx +++dmesg extract follows+++ [ 0.000000] Linux version 4.19.0-041900rc2-generic (kernel@kathleen) (gcc version 8.2.0 (Ubuntu 8.2.0-4ubuntu1)) #201809022230 SMP Sun Sep 2 22:32:22 UTC 2018 [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-4.19.0-041900rc2-generic root=<redacted> amdgpu.cik_support=1 radeon.cik_support=0 amdgpu.dc=0 amdgpu.dc_log=1 drm.debug=0 ...
