How to enable Amd Graphics card?

[unbalancedskunk]

İ have installed drm-kmod. My computer is Dell Inspiron 5559. İ enabled graphics by processor but i would like to use my graphics card which is AMD Radeon R5 M335. Is there a way to enable it? I am looking for single command to use graphics card.

These are the cards known to work,

Graphics/AMD-GPU-Matrix - FreeBSD Wiki

The following output can be interesting,

pciconf -lv | egrep -i "amd|radeon"

In rc.conf put something like,

kld_list="drm radeonkms"

For newer cards its,

kld_list="drm amdgpu"

Try first without /etc/X11/xorg.conf
It if it fails make a small /etc/X11/xorg.conf

Section "Device"
    Identifier "Card0"
    Option "AccelMethod" "EXA"
    BusID "PC:1:0:0"
    Screen 0
EndSection
Section "Screen"
    Identifier "Screen0"
    Device       "Card0"
    Monitor    "Monitor0"
    SubSection "Display"
        Depth     24
    EndSubSection

Alain De Vos thank you but when i would like to activate graphics card for specific games. How do i do that? Will it be enabled automatically for all games?

 

[Alain De Vos]

You install and run a window manager for most games,

Chapter 5. The X Window System

This chapter describes how to install and configure Xorg on FreeBSD, which provides the open source X Window System used to provide a graphical environment

unbalancedskunk are you talking about a notebook with hybrid graphics ??

 

[unbalancedskunk]

meaw229a may be, my processor has graphics module and i have one graphics card too.

 

[meaw229a]

I guess you have one of the hybrid graphics notebooks but you should give us bit more information about your hardware.
There is a lot of technical knowledge on this forums but to help, people need to know more exact what system you have.

I have one of this notebooks. Intel integrated graphics but also a amd card and I'm working to get my head around it if I can
make this work on FreeBSD.

A few points.

Custom Xorg configuartions should be put into /usr/local/etc/X11/xorg.conf.d
Loading drm by hand is not needed when amdgpu, i915kms etc.. gets already called.
Color deph gets also set to the best by the xorg driver unless you want a lower.
The reason to use EXA instead of glamor?

 

[Alain De Vos]

I did a test with glxgears and it gave serious speed improvement fps on my card using EXA.

Alain De Vos thank you this works but now i have other problem. I have Amd graphics but it shows Nvidia. When i choose Nvidia it works well. Should it be a problem?
