5.4.5. Video Cards - should I install graphics/drm-kmod?

Hello,
I am installing FreeBSD for the first time and I got stuck at 5.4.5. Video Cards in Handbook.

I am now installing on old PC to try it out but I am interested in general steps.

I identified my GPU as Radeon HD 4000 RV730 XT. So I figured I'll need to modify config file accordingly:

Code:
/usr/local/etc/X11/xorg.conf.d/driver-radeon.conf

Section "Device"
    Identifier "Card0"
    Driver     "radeon"
EndSection

However I do not understand how to use graphics/drm-kmod. Am I supposed to run make install and it will figure out automatically what to install?

I am sorry if this is obvious. I read the Handbook from the start but I am probably missing some clue on how to figure this out.
 
I followed the guide and set the driver to radeonkms. I also installed drm-kmod. drm-legacy-kmod was installed automatically.

However, startx does not work. In /var/log/Xorg.0.log I found:

Code:
(WW) Warning, couldn't open module radeonkms
(EE) Failed to load module "radeonkms" (module does not exist, 0)
(EE) No drivers available.
(EE) Fatal server error:
(EE) no screens found(EE)

I also modified /etc/rc.conf:
Code:
kld_list="/boot/modules/radeonkms.ko"
 
For RV730 it should be "radeonkms" , "drm-kmod". Try drm-kmod in stead of legacy.
Try to remove drm-legacy-kmod-...
Maybe you should install drm-fbsd...-kmod-...
"For newer Intel and AMD hardware, please use graphics/drm-kmod which will pick an appropriate driver for your system"
 
I followed the guide and set the driver to radeonkms.
(WW) Warning, couldn't open module radeonkms
(EE) Failed to load module "radeonkms" (module does not exist, 0)
(EE) No drivers available.
I also modified /etc/rc.conf:

Disable /usr/local/etc/X11/xorg.conf.d/driver-radeon.conf by renaming, e.g. driver-radeon.conf.0, or delete it . graphics/drm-legacy-kmod doesn’t need a [EDIT:driver] config file. Make sure you are in the video group: 5.4.2. User Group for Accelerated Video

I renamed the config file. X now starts however the screen gets disconnected and monitor doesn't detect any input. From the /var/log/Xorg.0.log:
Code:
(WW) Falling back to old probe method for modesetting
(WW) Falling back to old probe method for scfb
...
(WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
...
(WW) RADEON(0): 3 ZaphoHeads crtcs unavailable. Some outputs will stay off.
...
(WW) RADEON(0): Failed to set mode on CRTC 0
(EE) RADEON(0): Failed to enable any CRTC

I forgot to mention that X works with VESA driver if that's helpful.

I also tried to replace xf86-video-ati with xf86-video-ati-legacy by installing a port. However I got:
Code:
===>>> Port directory: /usr/ports/x11-drivers/xf86-video-ati-legacy

===>>> This port is marked BROKEN
===>>> does not build with xorg-server 1.20.7
 
From startx itself:
Code:
drmn0: error: No GEM object associated to handle 0x00000400 can't create framebuffer
failed to add FB for modeset
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Internal error: Could not resolve keysym XF86FullScreen
 
Back at these errors.
I followed the guide and set the driver to radeonkms. I also installed drm-kmod. drm-legacy-kmod was installed automatically.

However, startx does not work. In /var/log/Xorg.0.log I found:

Code:
(WW) Warning, couldn't open module radeonkms
(EE) Failed to load module "radeonkms" (module does not exist, 0)
(EE) No drivers available.
(EE) Fatal server error:
(EE) no screens found(EE)

I also modified /etc/rc.conf:
Code:
kld_list="/boot/modules/radeonkms.ko"
 
If you use drm-kmod it's good to check if there is not more than one video card in the PC with
pciconf -lv.
If there is more than one set the pci id in xorg.conf
And don't specify a driver.

I found no other video card.
I commented out the driver name but then it results in load of radeon instead of radeonkms and screen goes blank/off.
 
What's the output of :
cat /var/log/Xorg.0.log | grep -i driver
What you requested plus error in different part of log file in an image, sorry.

Please install misc/pastebinit . Use it next time, usage: cat /var/log/Xorg.0.log | pastebinit, that will return a URL, post that URL.

Please post the output (URL) of pciconf -lv | grep -B3 display | pastebinit , to make sure the correct driver is used. I'm unsure which driver is used at the moment, please clarify.

Currently, drivers are not selected explicitly and commented out as requested previously. I see I misread name of the graphics card. I apologize for that.

I switched to a different monitor and connected it using VGA instead of DVI. After startx, the screen still goes to sleep on Alt-F9. Switching back to Alt-F1:

I believe that x11-drivers/xf86-video-ati is the needed driver. Make sure it’s installed: pkg info | grep xf86-video-ati , set in /usr/local/etc/X11/xorg.conf.d/driver-radeon.conf:
Code:
Section "Device"
    Identifier "Card0"
    Driver     "radeon"
EndSection

run startx, report back about the result, and please post /var/log/Xorg.0.log.
 
From where is radeonkms.ko loaded?
I believe it is loaded automatically since I didn't modify any other files and didn't load it manually. In /boot/loader.conf is only fuse.

The driver is installed as per: https://pastebin.com/W0xNCXBS

Section "Device" Identifier "Card0" Driver "radeon" EndSection
I saved the log before any setting and after this setting.

It seems to load the same kernel modules anyway. Just as a side note, on the wiki, it says to use radeonkms for similar cards and not radeon. Though as demonstrated earlier it doesn't work with either. https://wiki.freebsd.org/Graphics/AMD-GPU-Matrix
 
You should actually read /var/log/Xorg.0.log at least once, it's very clear from the log what Xorg calls "module" and what it tries to load.

Yes, I have read it many, many times by now. And yes, I saw that it loads modules ati_drv.so and radeon_drv.so. But I also read the man page for kldstat which says "The kldstat utility displays the status of any files dynamically linked into the kernel."

And as far as I know .ko stands for "kernel object". Thus I called it kernel module. EDIT: As in radeonkms.ko.

Not quite, there are two radeon driver from different packages. The wiki is referring to the radeonkms.ko driver installed by graphics/drm-kmod (graphics/drm-fbsd12.0-kmod actually, run pkg info -l drm-fbsd12.0-kmod), whereas radeon_drv.so (aka radeon) is installed by x11-drivers/xf86-video-ati.

- radeonkms.ko is set in rc.conf(5), loaded by kldload(2)
- radeon_drv.so, aka "radeon”, is set in /usr/local/etc/X11/xorg.conf.d/driver-radeon.conf, loaded by xorg.

Concerning the Xorg.0.logs:
Code:
[   475.804] failed to add FB for modeset
[   475.804] (WW) RADEON(0): Failed to set mode on CRTC 0
[   475.812] (EE) RADEON(0): Failed to enable any CRTC
(https://pastebin.com/8KAiMRLB, https://pastebin.com/7ivBK7zd9 )

There is an older bug report PR 232499 regarding x11-drivers/xf86-video-ati and the error messages. Op is reporting being successful with, x11-drivers/xf86-video-ati-legacy. You could try that driver, but it is currently marked as broken, a patch is available, easy to apply.

Thank you for investigation and clarification. I ran across this bug report previously but didn't get further than the broken message.

I applied the patch and compiled. Then rebooted and started X. I am not sure what's the take on this: https://pastebin.com/iM7qVx3m

EDIT: I also removed the xf86-video-ati.
