I have 6 Monitors on 2 GPU´s:
Nvidea Quadro 4 monitors
AMD 9600 XT 2 Monitors
The amd card is used and i can use the 2 Monitors
The quadro isnt used at all, i see it in hardware manager and installed the prop drivers but it dont get used sadly. On other Systems its not a Problem.
Apologies for only now answering. But I was, and still am, a bit hesitant because I have never had to deal with this many screens before, nor AMD-Nvidia.
Anyhow, I noticed you don’t have any hybrid drivers installed, so let’s start with that because it’s the most obvious thing to start with, so let’s get it out of thee way. Install it first:
mhwd --install video-hybrid-amd-nvidia-prime
Then provide the output for:
sudo inxi --graphics --filter --no-host --width
And
xrandr
Again please.
And let’s hope for the best, shall we.
Edit:
I don’t have anything to do with hybrid graphics, so this is pure speculation.
I know that on laptops with dual GPUs you have to run applications with prime-run for nvidia and prefix the command with DRI_PRIME=1 for AMD (I don’t know where that variable value comes from, or if it ever changes from 1).
So, please try running your applications either like thiss, for Nvidia:
prime-run <commandToRun>
or, for the AMD GPU:
DRI_PRIME=1 <commandToRun>
Where<commandToRun>is, well, the command to run.
That should offload rendering for that application to either the AMD GPU or the Nvidia GPU.

yes i have many monitors and no problem for late reply, i appriate every help
the prime run dont change anything, yes i could offload render tasks but i want to use all 6 displays again
intrest thing, when i dont use the hybrid driver on startup all 6 monitors getting woke up, and i the a command line, as soon as kde loads (or at the moment the drivers load) they go off. after installing the hybrid driver that dont happen. only the two AMD monitors are used
the output shows that the 4 monitors are disconnected, is there any way to connect them manually? then i could make a startup script. just throwing an idea at the wall
I read a lot of posts and as far as i can tell is that what i want is not possible, xrandr seem to not support what i need, there a mosaik and Xinerama tricks that breaks 3d accel or performance drops about 30 %, breaking features and so on.
if i dont missed something or didnt find the right post its not possible.
the sad thing is that there are posts since 2014 (and possible before) from people that have the same problem without anyone get this fixed.
and i didnt find any source that adress this, so if a fix ever comes nobody knows when.
the really sad think about this is that i dont want to move away from manjaro, i love it so far, gaming is huge thing that i compromise with but not my monitors…
i let it installed for know, i hope that there is a magic fix or a workaround i can deal with, we will see
Apologies. Not ever having worked with any of that, it was the only thing that made sense to me. I should have consulted with the Arch wiki. My mistake.
