Solved Xorg do not start

[Dayhoku]

I installed FreeBSD 13 on an Asus Laptop with amd64 processor and ' % startx' produces a serie of information that I am not able to resolve.

xauth: file /root/ .serverauth.2744 does not exist
xauth: file /root/ .Xauthority does not exist
xauth: file /root/ .Xauthority does not exist
......
......
.......
......
(EE) Fatal server error:
(EE) cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices
.......
......
xinit: unable to connect to X server:
Connection refused

p.s.
I tryed NomadBSD and it loaded perfectly the graphic interface using scfb instead and starting slim
How can I do that in FreeBSD

Could someone please help me

Ok, install graphics/drm-kmod and X should start working. Turn off SLiM while testing, it's much easier to test by simply running startx. Once you're satisfied X starts properly with startx you can enable SLiM again.

graphics/drm-kmod is already installed , Slim is used by NomasBSD ( which is on a USB pen ) . Unfortunately Xorg (on the HDD) still doesn't work

graphics/drm-kmod is already installed

But is your driver enabled in /etc/rc.conf?
kld_list="amdgpu"

Is your user member of the "video" group? If not you are not allowed to run the video driver, which prevents Xorg from starting.

Thank you very much bsduck !!! I am a true newbie .
I added kld_list="amdgpu" at /etc/rc.conf, reboot and finally everything went well !
