Hi,

I am writing a FreeBSD application in which I need to know the graphics 
configurations for different graphics chips.

1) nvidia - I think I know this case. this needs installation of 
packages nvidia-driver / nvidia-settings / nvidia-texture-tools / 
nvidia-xconfig. The user then needs to set in /etc/rc.conf :

kld_list="/boot/modules/nvidia.ko /boot/modules/nvidia-modesetting.ko"

The user also needs to configure xorg.conf (most easily done by just 
running nvidia-xconfig).

2) radeon - I think I know this case too. The user just needs to set in 
/etc/rc.conf :

kld_list="/boot/kernel/radeon.ko /boot/kernel/radeonkms.ko"

The user does not need to configure xorg.conf. Xorg configures itself.

3) amdgpu - Not sure here. Appears to me that this needs the user to 
install the xf86-video-amdgpu package. Anything else ?

4) intel - Not sure here too. Appears to me that this needs the user to 
install the xf86-video-intel package. Anything else ? Further, 
/boot/kernel also holds i915.ko and i915kms.ko. When are these modules 
needed ?


Thanks for any information.
