No AMD but...

$ lspci -nnn|grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core
processor Graphics Controller [8086:0166] (rev 09)
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108M [NVS
5400M] [10de:0def] (rev a1)

No error message & still the same issue with both these arguments.

I've been using Parabola on this computer for several years without
problems, but none of my disks were encrypted.

Thanks for the support,
