     First, please stop top-posting.  It's rather rude.

     Did you mean rEFInd perhaps?

     The handbook and man pages for FreeBSD are available on-line.  TrueOS
has its own handbook, also available on-line, that provides additional,
TrueOS-specific information.

     Like the man wrote, you could try radeonkms instead of amdgpu.  In
his posting, IIRC, he recommended a sysctl variable be set to a certain
value.  You may wish to read that part again.

     If the device has not first been detected and recognized by a driver
in the kernel, how could xorg be aware of it?  The driver obviously has to
be loaded first, preferably at boot time.  The same, I presume, would be
true for a LINUX system, too.
