How to use two gpus (intel and nvidia) attached to two monitors on FreeBSD

marietto

Hello to everyone.

Actually I have two monitors,but usually I use only one of them. The monitor I use everyday with FreeBSD is attached to the HDMI port of the “VGA compatible controller: Intel Corporation CoffeeLake-S GT2 [UHD Graphics 630] (rev 02)” graphic chipset. And it works well. Sometimes,when I want to virtualize Linux,I attach the second screen to the HDMI port of the second GPU I have,the Nvidia Geforce RTX 2080 ti and in this way I can use even the second one. But I don't want to be forced to run bhyve to use the second screen. It could be useful even when I want to make some 3d modelling using Blender on the first one and using the second one to watch some tutorial. Can someone give me some suggestions about how to do that ? I tried to figure it out how to configure everything but it didn’t work. The monitor attached to the nvidia card remained black.

I tried with this xorg.conf :

Section "Device"
Identifier  "Card0"
Driver      "intel"
BusID       "PCI:0:2:0"
EndSection

Section "Device"
Identifier  "Card1"
Driver      "nvidia"
BusID       "PCI:2:0:0"
EndSection

Monitor 1 is attached to the HDMI port of the intel gpu and the monitor 2 is attached to the HDMI port of the nvidia GPU. Does it seems correct ? on FreeBSD I have installed these packages for the gpus :

1) xf86-video-intel-2.99.917.916_1,1 X.Org legacy driver for Intel integrated graphics chipsets

2) nvidia-driver-510.60.02 NVidia graphics card binary drivers for hardware OpenGL rendering

3) nvidia-settings

my /etc/rc.conf looks like this :

kld_list="nvidia-modeset"

my /boot/loader.conf like this :

nvidia_load="YES"

This is what happens after the rebooting :

# kldstat | grep nvidia

 3    2 0xffffffff826b6000  2c4e1c0 nvidia.ko
19    1 0xffffffff86031000    fd310 nvidia-modeset.ko

# xrandr --listproviders

Providers: number : 1
Provider 0: id: 0x43 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 1 associated providers: 0 name:Intel

the nvidia card is not detected. But,the utility nvidia-settings shows that the driver detects two screens and that the 2 monitor is attached to the nvidia card. I’ve captured some screenshots and I’ve attached them,hoping that they can be useful to understand whats wrong.

Monitor 2 is turned on and I can see the mouse pointer that can go over it,BUT there is nothing inside of it,it is totally black.

I tried also with this xorg.conf :

Section "Device"
Identifier  "Card0"
Driver      "intel"
BusID       "PCI:0:2:0"
EndSection

Section "Device"
Identifier  "Card1"
Driver      "modesetting"
BusID       "PCI:2:0:0"
EndSection

Using modesetting the monitor does not turn on at all. I forgot to say that on my BIOS I have configured the intel graphic chipset as primary.

marietto See this thread.

What's your setup? Are you trying to combine on-board graphics with a card?
What says xrandr?
What does X -configure make of it?

I'm not certain about it, but I think you need 2 monitor sections too. That's what I have but it's for a Nvidia Quadro duo card.
Never seen that "modesetting" as driver name. Is it for when you have 2 different monitors?

marietto

The Intel integrated gpu has only one HDMI port. To attach two monitors on two nvidia gpu ports is very unconfortable for me,because often I use the bhyve virtual machines. And if I want to do that,I should reboot the PC. Anyway this is the scenario :

https://pastebin.ubuntu.com/p/pHNTYGBs33/

I think I need some splitter that allows me to attach two monitors on the intel hdmi port. But I'm sure that I can't turn on both the monitors using one only GPU even if with the splitter. The splitter allows to switch from the monitor 1 to 2,not to have both the monitors running. Right ?

rvp

marietto That xorg.conf looks OK, but, I don't think you need to install those legacy Intel and nVidia drivers. The modesetting driver (included the xorg meta-pkg) along with the drm-kmod meta-pkg should be all that is needed. And, you'll have to add kld_list="/boot/modules/i915kms.ko" etc. to /etc/rc.conf, of course, to load the DRMKMS modules at boot-time.

If any of your cards have multiple output ports (say, VGA and HDMI), then you don't need a "splitter" either. Driving multiple outputs of a single card is well supported in all recent X servers.

marietto

I've found the reason why it does not work and I've been able to make it work,at least,partially. The problem of the black screen arises because I'm using xfce4. It misses some components inside the code and it can't replicate on the monitor 2 what is displayed on the monitor 1. I've installed mate and it happened the same. So,I've got the idea. I've chosen KDE Plasma as DM and boom. It has been able to display on the monitor 2 the content of the monitor 1. Unfortunately the magic did not last too long. KDE crashed many times and at the end I've seen again the black screen on the monitor 2. So,what I want to do can be done,but only KDE is partially able to do it. If KDE does it partially,do you know another DM that can do it better ? Maybe Wayland ? Below you can see what's the KDE component that crashed multiple times.

marietto

and my xorg.conf ? what are the parameters to put inside of it ? Why I need a " splitter " if I use two gpus ? you know how many ports there are in two nvidia gpus ? The idea is to attach a monitor to the intel gpu port and another to the nvidia gpu port.

rvp

marietto Why I need a " splitter " if I use two gpus

Some cards can send signals to multiple outputs: LVDS, VGA, HDMI, DisplayPort..., and you can connect a monitor to each. Does either of your cards support this?

marietto xorg.conf should be like this ?

For the Intel card the driver should be modesetting and you should load the /boot/modules/i915kms.ko module in rc.conf. I don't know about the nVidia card. The drm-fbsd13-kmod package only has DRM drivers for AMD and Intel HW.

$ pkg info -l drm-fbsd13-kmod
drm-fbsd13-kmod-5.4.191.g20220604_1:
        /boot/modules/amdgpu.ko
        /boot/modules/drm.ko
        /boot/modules/i915kms.ko
        /boot/modules/linuxkpi_gplv2.ko
        /boot/modules/radeonkms.ko
        /boot/modules/ttm.ko
[...]
$

For nVidia, I don't know which of these is correct (don't have any nVidia HW--and, won't buy one ever):

$ pkg search ^nvidia
nvidia-driver-510.60.02        NVidia graphics card binary drivers for hardware OpenGL rendering

$

The Driver name would either be nvidia or nouveau--the man-page should tell you (after you locate it it with pkg info -l ...).

marietto

xorg.conf should be like this ?


Section "Device"
Identifier  "Card0"
Driver      "i915kms"
BusID       "PCI:0:2:0"
EndSection

Section "Device"
Identifier  "Card1"
Driver      "modesetting"
BusID       "PCI:2:0:0"
EndSection

marietto

I think that the configuration closer to the working one is the following :


Section "Device"
        Identifier  "Card0"
        Driver      "intel"
        BusID       "PCI:0:2:0"
        
EndSection
        
Section "Device"
        Identifier  "Card1"
        Driver      "nvidia"             
        BusID       "PCI:2:0:0"
EndSection

because I see the mouse goes across the monitor attached to the nvidia card even if it is totally black and the monitor attached to the intel gpu works good. BUT I don't see any desktop manager on the monitor attached to the nvidia card. So,I presume there aren't problems regarding xorg or the drivers,but the problem is that maybe I should run the desktop manager on the black monitor. I've added this line on the file /home/user/.xinitrc :

set DISPLAY=:0.1 exec ck-launch-session dbus-launch --exit-with-session startplasma-x11

but nothing,it does not work. the screen attached on the nvidia card is still black even if I see the mouse goes there.

rvp

marietto What's the output of xrandr -q?

MG_

marietto Which of 2 graphics outputs does xrandr show? Kind of relevant... There's the problem.
And which of both work with single display?
Also, if you configured X to use 2 displays and it shows no error, but you can only see 1 while the other seems to exist for the mouse pointer, I'd guess out of sync. Are the frequencies and refresh rates compatible?

Today I made another experiment. I've changed the PCI slot position of the nvidia graphic cards and I've changed the gpu that should be used as default from the BIOS from the intel gpu to the geforce 1060 gpu. Actually I'm using this xorg.conf :

https://pastebin.ubuntu.com/p/DhW6RHS3zb/

instead this is the Xorg.0.log file :

https://pastebin.ubuntu.com/p/YtdPq9fngQ/

In front of me I have the AOC monitor,that's connected to the HDMI port of the 1060. On my right I have the monitor samsung synchmaster,that's connected to the HDMI port of the intel GPU. The 3 gpu (rtx 2080 ti is non connected to any monitor because I want to use it to be passed thru on a bhyve vm.

What happens is that the samsung monitor works partially. The only 2 apps which can be directed to it (it is attached to the Intel GPU with the HDMI cable) are :

[marietto@marietto ~]$ export DISPLAY=:0.1 ; konsole

and :

[marietto@marietto ~]$ export DISPLAY=:0.1 ; chrome

(firefox can be displayed only on the screen 0 : don't know why)

Here you can find the list of every PCI device attached to my PC :

https://pastebin.ubuntu.com/p/Gx5DqckFQP/

what else ? the samsung synchmaster screen always worked partially. When I told you that it didn't work was because I didn't know that I could export some application to the DISPLAY=:0.1. But anyway,even in this case,this kind of usage is not comfortable at all. I can't run another session of xorg because it says that one session is already running. Only some applications are displayed on the secondary screen (samsung synchmaster + intel GPU). And If I invert the cable and the drivers on xorg.conf,placing as primary gpu the intel gpu attached to the AOC monitor and as secondary gpu the nvidia 1060 attached to the samsung synchmaster,the behavior is the same,with the difference that I've inverted the monitors. I've tried to enable xinerama,but it does not work good. It freezes the mouse and anyway,attaching virtually two screens into only one is ridicolous,because they aren't attached physically.

arandr tells that the only monitor connected is the HDMI-0,the monitor AOC connected to the nvidia 1060 gpu. But if I invert the drivers on xorg.conf and the cables,the only monitor connected will be again the HDMI-0,but this time it will be the Samsung Synchmaster.

marietto What happens is that the samsung monitor works partially. The only 2 apps which can be directed to it (it is attached to the Intel GPU with the HDMI cable)

What's the output of:

$ xrandr --display :1 -q
$ xrandr --screen 1 -q

Q: What do both monitors display if you run Xorg without a DE ie. using twm as the window manager in .xinitrc? if you do

xsetroot -fg rgb:30/30/30 -bg black -mod 3 3

does the background pattern change on both monitors when they're connected to 2 different cards?

marietto I can't run another session of xorg because it says that one session is already running.

This should be possible since you have 2 graphics cards. You may have to create 2 xorg.conf files and then point each Xorg server to its own file. The second X server you'll have to run on display :1

marietto I see some progress anyway. DP-0 is AOC monitor and the 1060 ; HDMI-0 is Samsung SynchMaster and the 1060,but it is disconnected. Why ?

Try rebooting with both monitors connected and that nvidia card as primary display in BIOS. The intel Xorg driver has a Option "ReprobeOutputs" "On" to force the kernel to re-detect monitors plugged in after booting. See if the nvidia driver has something similar...

anyway,I don't have a solution. Do you ?

I've tried to configure it in a different way. I've attached my two monitors to the same graphic card (gtx 1060). Can you give a look at this xorg.conf file ? If you see some error,please tell me,because the samsung monitor does not turn on :

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 1060"
    BusID          "PCI:1:0:0"
EndSection

I've only saved the file as /usr/local/etc/X11/xorg.conf.d/nvidia-driver.conf

# xrandr -q

I see some progress anyway. DP-0 is AOC monitor and the 1060 ; HDMI-0 is Samsung SynchMaster and the 1060,but it is disconnected. Why ?

Tenacity always win. And we have a lot. Our fuel is the "love" we feel for FreeBSD,I think. With the help of you all I've found the working configuration. Now I have two monitors connected :

# xrandr -q

And Infact I can move the windows from a screen to another one. I've even created some application launcher on the monitor 2. What I don't know how to do is how to create a new taskbar at the bottom of the monitor 2 (HDMI-0). I've been able only to create the thunar,firefox and konsole launchers. Another thing to change is to invert the monitors. I mean. As soon as FreeBSD boot,I see the boot messages on the HDMI-0 monitor (the samsung synchmaster),instead I want to see them on the AOC monitor. Later,when FreeBSD is ready to be used and the desktop manager has been loaded on the samsung screen,it enables also the AOC monitor. I would like to do the opposite. And the last thing that it's not so good is that if I want to use the monitor that's in front of my eyes (AOC) I should move the mouse on the right side of the monitor that's on my right (samsung synchmaster). Anyway,this is the xorg.conf file that I have created :

Anyway it seems there is a bug. If I turn off one monitor,all the icons on the desktop and the background images applied are broken and when I move a window from a screen to another one I see that it will not be of the same size of the screen anymore. I presume that if I turn off a monitor physically,it will be turned off also virtually. And when I turn it on again,it remains turned off virtually.

Anyway,in my opinion I haven't found a method to use both my gpus (intel and nvidia),but only one,the 1060,where I have attached both the monitors. I call this "workaround". Do you want to continue helping ? I don't want to surrend. Someone said to me : "No. This is going to be a challenge. While I don't have a magic incantation". Why is so difficult ? I would like to change also the title of this thread,but it seems that I can't.

What would the title be?
