How to use two screens at the same time while I'm using FreeBSD.

I guess this is your issue now:
1658514402712.png
 
Because I'm a geek. I like to squeeze my brain, because if my mind is trained to solve problems it stays young: D
Jokes aside but not so much,only as a lastest experiment I will try to use the 1060 as primary and the intel and the 2080 ti as secondary.
 
Have you already thought that this part could be necessary inside the Xorg conf files ?
Code: 
Section "Screen"

    Identifier "Screen1"

    Device     "Card1"

    Monitor    "Monitor1"

    SubSection "Display"

        Viewport   0 0

        Depth     1

I spend and hour of two to test whatever I could run in 13.1 Release.
Two graphics cards: amdgpu and intel.
I couldn't get anything except two separate screens (so, u have to run 'two' window managers - tried with openbox and It was working fine),
or Xinerama - tried that with openbox and KDE, but couldn't really configure anything in KDE as randr is disabled because of xinerama.
Ziomario I will now write slow so u can read it whole.

What I have added to /etc/rc.conf:
Code: 
kld_list="amdgpu i915kms"
without that I couldn't even get text console on intel gpu (even if it was set as boot card in bios).

now the /usr/local/etc/X11/xorg.conf.d/xorg.conf:
Code: 
Section "ServerLayout"
        Identifier "layout"
        Screen 0 "intel"
        Screen 1 "amdgpu"
#       Screen "amdgpu" LeftOf "intel"
#Option "Xinerama" "1"
EndSection

Section "Device"
        Identifier "amdgpu"
        Driver "amdgpu"
        BusID "3@0:0:0" #replace with information from lspci -v
EndSection

Section "Screen"
        Identifier "amdgpu"
        Device "amdgpu"
        Option "AllowEmptyInitialConfiguration"
EndSection

Section "Device"
        Identifier "intel"
        BusID   "0@0:2:0" #same as above lspci -v
        Driver "intel"
EndSection

Section "Screen"
        Identifier "intel"
        Device "intel"
EndSection

Just by uncommenting Xinerama line you can get both screens acting like one desktop, but with limitations like no acceleration, no randr etc.
You can try to replace amdgpu with nvidia, and it could possibly work the same.
I was just using search site, and some linux howto's. I can bet this config could be even simpler and had working without forcing xinerama but require linux.

This topic isn't really FreeBSD specific, and there is lots of Linux howto's on how to setup multihead multimonitor Xorg on the internets.

PS. if you want to run for example double window managers on separate screens, just do in your .xinitrc:
Code: 
DISPLAY=:0.0 exec openbox-session &
DISPLAY=:0.1 exec openbox-session
Nothing really amazing but at least you can start from here and customise this to your liking.

maybe this...but anyway,it didn't work. For which kind of error ? can u see guess it ?
 
I've tried to change the priorities assigned by the BIOS to my gpus. I have 4 slots :

1) IGV
2) pcie 1
3) pcie 2
4) pcie 3

I have attached one monitor to the slot 2,3 and 4 and I've realized that they belong to one only GPU. Can someone guess to which GPU they belong ?

Let's recap ? :

Code: 
/etc/rc.conf :


kld_list="nvidia nvidia-modeset"


/boot/loader.conf


nothing related to the gpu


/etc/X11/


no conf files.


/usr/local/etc/X11/xorg.conf.d/gedit 40-card0-intel.conf

The issue, I believe, lies in this message:

Code: 
Using the first device section listed.
[    68.520] (**) |   |-->Device "Card0"
[    68.520] (**) |   |-->GPUDevice "Card1"

Read the following documentation provided by NVIDIA:
Chapter 34. Offloading Graphics Display with RandR 1.4
Chapter 35. PRIME Render Offload

So I would try to blend that Intel part of your configuration which is currently working with what is suggested by NVIDIA documentation.

What also might be worth to give it a shot is to make the NVIDIA primary and the Intel secondary. From what I got what you are looking for the order of the two cards doesn't matter to you as long as one screen is directed by the Intel device and the other one by the NVIDIA GPU.

One last inquiry, the Xserver is running as root, right ? Because some of the warnings are bit confusing.

I'm not sure that I can do this. I think I have only 1 option to try :

a) Intel gpu as primary,nvidia 1060 as offloading graphic display,2080 ti kept free to be passed in bhyve

because yesterday I've ascertained that my BIOS accept only :

-) intel gpu as primary
-) 2080 ti as primary

I don't know why but the 1060 is not accepted as primary gpu. It is not detected at all. So,keeping in consideration that I can't choose the 2080 ti as primary,because if I do this I can't pass it to a guest os virtualized with bhyve,I can only use the intel gpu as primary.
 
NVIDIA says :

To use the NVIDIA driver as an RandR 1.4 output source provider, the X server needs to be configured to use the NVIDIA driver for its primary screen and to use the “modesetting” driver for the other graphics device.
Click to expand...

So,my only option here is to use the geforce 1060 NVIDIA driver as primary screen. But it will not work since my BIOS does not accept it as primary gpu. Only the intel gpu is accepted. Or the 2080 ti,that I can't choose. I don't know,maybe this work :

Code: 
Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"

Section "Device"
    Identifier "nvidia"

Section "Screen"

EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"

or,maybe :


Code:

      Screen 0 "iGPU"
      Option "AllowNVIDIAGPUScreens"
    EndSection

Perhaps the BIOS is only able to recognize the first two cards on the PCI bus, according to the following output the 1060 is last, how about putting it second on the mainboard, is that a possibility?

Code: 
pciconf -vl

vgapci2@pci0:0:2:0:     class=0x030000 rev=0x02 hdr=0x00 vendor=0x8086 device=0x3e98 subvendor=0x1458 subdevice=0xd000
    vendor     = 'Intel Corporation'
    device     = 'CoffeeLake-S GT2 [UHD Graphics 630]'
    class      = display
    subclass   = VGA

vgapci0@pci0:1:0:0:     class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1e04 subvendor=0x19da subdevice=0x2503
vendor     = 'NVIDIA Corporation'
device     = 'TU102 [GeForce RTX 2080 Ti]'
class      = display
subclass   = VGA

vgapci1@pci0:2:0:0:     class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1c02 subvendor=0x19da subdevice=0x2438
    vendor     = 'NVIDIA Corporation'
    device     = 'GP106 [GeForce GTX 1060 3GB]'
    class      = display
    subclass   = VGA

Both aforementioend configurations are worth a shot, however based on the already done testing regarding the Intel card, the best bet would be, to stick with the intel driver instead of using modesetting (which did not recognize the Intel card). Perhaps you can still publish the information I inquired in my last two, three posts, which might shade some additional light on the situation.
 
---> Perhaps the BIOS is only able to recognize the first two cards on the PCI bus, according to the following output the 1060 is last, how about putting it second on the mainboard, is that a possibility ?

maybe yes. But I need some help from you,because I have no competence in the hardware area. Problem is that the cable that I'm using to power on the 1060 is too short. I need to find the proper connector to prolong it. I need to know what's the english technical name to buy it. I've attached a screenshot to show you. If the slot occupied by the graphic cards is inverted,on the picture below you can see of how much it should be stretched.

----> perhaps you can still publish the information I inquired in my last two, three posts, which might shade some additional light on the situation.

can you ask again the informations that you need to know ?

The GPU connector is called a P8 connector (8 pin connector), which is usually assembled from a P2+P6 connector.
Extension cable shouldn't be an issue.


What might give a clue, if this could be a feasible solution , would be to temporary remove the 2080 and power-up the system if the 1060 appears in the BIOS.
 
Regarding the information, which might help:

Code: 
Can you please post the output of the following commands:
Code:
# prints, if your intel gpu has been proper detected by the kernel module
dmesg | grep drm
# prints gpu device handler have been created
ls -l /dev/dri
# prints the packages the fils belong to
pkg which /usr/local/lib/xorg/modules/drivers/modesetting_drv.so
pkg which /usr/local/lib/xorg/modules/drivers/intel_drv.so
# prints all installed packages which contain the word video
pkg info | grep video
# prints all installed nvidia driver
pkg info | grep nvidia
# prints who is part of the video group
getent group video
# print loaded kernel modules
kldstat

Can you please confirm, if X is running as root? Because there had been some strange warnings in the Xorg.0.log.

I think that I'm on the right track. I've modified the xorg.conf file like this :

EndSection

Section "Device"
Identifier  "Card1"

and now the monitor 2 is turned on and I can see the mouse pointer that can go on that monitor,BUT there is nothing inside of it,it is totally black. Any idea why is empty and black ? This is the new log file :

Just read again the whole thread and came across post of yours (#23), which to me looks like we are on the right track. The configuration mentioned in #23 is the same which you got right now. The difference is, that the 1060 is plugged in as well and is being detected by X as "GPUDevice", where the 2080 had been detected as usual "Device" according to the Xorg.0.log posted in #23.

I don't see any desktop manager on the monitor attached to the nvidia card but my mouse can go across it. 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 :

Code: 
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. Nothing happens. Maybe the error is there. We make some mistake trying to start the deskop manager on the black screen ?
 
My knowledge about KDE can be considered a faint fairytale, but I do remember that there had been something like a Display Setting where you could expand your "Desktop" from the first screen to the 2nd one.

If you are able to cross to the other side (2nd screen), then you should also be able to open an kde-console and drag it with your mouse over there. I'm sorry to ask this of you, but did you try that ? Move a window with your mouse to the 2nd screen ? 😅
 
The HDMI cable I used to attach the black screen to the geforce 1060 was broken. I changed it. Now I can see again the mouse across it. And I have removed the 2080 ti and I left only the 1060 and from the BIOS I've chosen it as primary GPU. It has been recognized. So,when I will get the power cable I will place the 1060 on the first slot to make it the primary GPU. And the intel and the 2080 ti will be secondary. Maybe this is the only solution. Regarding the informations requested (now I have chosen the intel gpu as primary and this xorg.conf file :
