Multi GPU and Multi monitor setup not working

Hi, I have a fresh install of Manjaro 22. I have 2 gpus in my system, GTX 1080 and 960.
One monitor is connected to gtx 1080 and 2 monitors connected to 960, but for some reason the monitors connected to the 960 are disabled. I tried downloading nvidia drivers properly but that led to no output at all (Had to uninstall drivers through TTY) any ideas how to proceed? I would like to have all my monitors working. FYI I am quite new in using GNU/Linux and Manjaro. Please dont hate me :slight_smile:

Hi,
Open terminal and show your output
inxi -v7azy
mhwd -l
xrandr

Hello,

Please do not mix your install with drivers downloaded from Nvidia. They do not have the kernel modules. Use the one from MHWD.
Open up Nvidia X Server Settings and create a fixed layout from it. Enable the secondary GPU and the Monitors attached to it. Use Absolute mode. Do not save the file as will create the xorg.conf. From the Preview (by clicking on Save to X Configuration File but without saving it) just copy the new information and add/replace the old information inside the /etc/X11/mhwd.d/nvidia.conf

You will have to have the PCI ID for each GPU and the metamodes in the proper order for each. Is not perfectly straight forward but there is a logic to that madness, still, needs to be done manually in your case.

Is it possible to find a step-by-step guide since X server outputs an error that not all options can be enabled, when trying to enable at least one monitor…Again, im most probably stupid and missing something.

The best resource i know of is Multihead - ArchWiki - start from there and also check the dedicated one for nvidia. Just keep in mind that xorg.conf file should be in your case the /etc/X11/mhwd.d/nvidia.conf

The problem is that I cannot enable properly any other monitors since when using xrandr --listmonitors
it only detects 1 monitor (which is on my 1080) and when trying to use these instructions :
https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-manjaro-linux
I only get a black screen on boot and nothing else…

Avoid using xrandr and also avoid the drivers from Nvidia Site and use the ones from our repos and install them via MHWD.

To enable the monitors, start with the System Settings and then make use of Nvidia X Server to make a fixed layout that match on both Settings. otherwise the ~/.local/share/kscreen will create you more issues than necessary and you will have to delete that folder over and over again.

I dont think I understood you correctly (Literally try and explain things to me as if Im five, since again Im new to GNU/Linux) but whenever I try to apply these settings, I only get a blank screen.And again, X Server complains that “The current settings cannot be completely applied” and when I press Apply What is possible, nothing changes. I used these instructions to install the drivers :

https://wiki.manjaro.org/index.php/Configure_NVIDIA_(non-free)_settings_and_load_them_on_Startup
https://paste.pics/399f3d7b8e4299bcc0d12106f2f7ade7
https://paste.pics/d6fbeb0d2d82dc5304f89cf073ef3245

Bring your parents please. I will explain to them.

On System Settings all 3 monitors are enabled. That is what i see from the screenshot. Now you set the Layout in Nvidia X Server Settings with both GPU’s and the 3 Monitors and you append the config information that is new - click on Save X to Configuration but without saving it you click on Preview and copy it and paste the correct part into to the /etc/X11/mhwd.d/nvidia.conf and then you reboot the system.

If unsure, share the content of the current /etc/X11/mhwd.d/nvidia.con and also the information you get from Preview once you set the Layout in Nvidia X Server Settings.

Nice, real funny.
The reason that I have a tick in the Enabled box is that otherwise I have no other way to properly set the layout.
Im not sure but if it will add any duplication into the nvidia.con

moderator edit - please use code tags next time

I also rebooted the system after all the instruction you gave me and it only gave me a blank screen with the mouse cursor and thats it…

Here is some base ground for the config to work. Is all in the wiki, but indeed is not as digestible as cookies with milk.

It seems you already added what you had in Preview to the nvidia.conf but without replacing the entries with the new ones, but rather adding them at the bottom.

  1. The config can’t have the
Section "ServerLayout"
    Identifier     "Layout0"

twice … Xorg does not make the difference and hence will choke.

  1. In your case you have 2 GPU’s but you managed to make 3 from them. Your GeForce GTX 960 is "Device1" and "Device2" at the same time … Will not work that way.

  2. When using Screen0 and Screen1 there will be no way to move application windows from one to another, unless TwinView is used via "Xinerama" "1" instead of the default "Xinerama" "0"

  3. When using metamodes with fixed/absolute position for one Monitor, then do it for all instead of nvidia-auto-select +0+0

The way you created the config is quite convoluted and i can’t decipher what intentions are behind your choices from there. Replace everything inside the /etc/X11/mhwd.d/nvidia.conf with this:

Is more generic and semi dynamic layout instead of a fixed one, but at least you should have a better starting point, once you reboot the system and no black screen, if my assessment was correct … but sometimes i’m not spot on things …

I replaced everything but when I Enable the monitors, I just get a blank screen up with the mouse cursor untill the changes revert back.

And when you have that mouse cursor, if you switch TTY with Ctrl+Alt+F2 and then back to TTY1 with Ctrl+Alt+F1 … can you see the desktop ?

Maybe your system needs to enable early KMS. See here:

When I press Ctrl+Alt+F1 I dont see the desktop, only again blank screen with the mouse cursor and after 3-4 seconds the changes revert, disabling the other 2 monitors. I tried enabling early KMS using the link you gave, but it made no difference.

This worked for me! I could not get 2 virtual displays Linux on Linux, until I saw this:

The thing is that Im not running Manjaro in a VM…I have it dual booted with windows.

Welp…I guess im just F’ed am I?

I do use xfce with nouveau, have 2 different nvidia cards, and 2 monitors.

BUT i do use multiseat, and i do not play, but use it as a workhorse.

I don’t have any conf-files (xorg.conf, nvidia …) and it works !

Multi-monitor did work out of the box. multiseat is a bit more difficult.
