Hi John Paul,
the append for the nvidia card is because on my quad and for what understand
the Link Electornics machine too there are two GPUS.
One is the default Nvidia GPU the other is the 6570.
If i dont set the append like i wrote before, my quad dont have linux running
and working on the 6570 with 3D acceleration and only the Nvidia running. In
this situation i can read the ring errors on dmesg about the Radeon and Radeon
wont turn on.
With this append line i tested with success Radeon HD4650, HD5650, HD 6570,
Radeon R5 2GB and R7 2GB. Some one reported to me have success with 6750 too.
Didnt test nowadays with RadeonSI gpus but some one report it is running ok it
too.
Ciao Luigi

Why not post the necessary commands to append to the kernel command line here?
On a GRUB-based systems, it should be enough to add the following line
video=offb:off video=radeonfb:off video=nouveaufb:off radeon.modeset=1
nouveau.modeset=0
to the variable GRUB_CMDLINE_LINUX_DEFAULT and then run "update-grub".
FWIW, you won't need the nVidia-specific parameters on a system with a Radeon
card
and vice versa.
