this discussion is probably best suited for the freebsd-x11 mailing 
list, but i think you can try a couple things:

- give NomadBSD a spin (https://nomadbsd.org/).  it's a live USB image 
that does a really good job at auto-detecting hardware and giving you 
nice desktop.  it's based on freebsd-13.0.  you can also install it on 
your disk if everything looks good.  i frequently use it to test 
hardware support on new systems i encounter.

- it's hard to tell without any hardware info provided, but its possible 
you have an older AMD gpu, as such you might want to try using radeonkms 
in rc.conf rather than amdgpu.

if neither of those things help i'd definitely suggest subscribing to 
the freebsd-x11@ mailing list to get the appropriate eyes on things:
