3 monitors 2 gpu (nvidia + intel i5)

Hi,

I am newbie and i need help to write my xorg.conf to extends 3 monitors with 2 gpu (nvidia + intel i5)

After a restart only 2 screens display.

The third monitor display after :

xrandr --setprovideroutputsource 1 0

Then I have to manually extend screens to properly arrange them. I can not save my configuration.

I tried this script but screens are not correctly extended (superimposed)

#!/bin/sh
xrandr --setprovideroutputsource 1 0
xrandr --output DVI-I-1 --primary --mode 1920x1080
xrandr --output VGA-1 --right-of DVI-I-1 --mode 1680x1050
xrandr --output DVI-I-0 --left-of DVI-I-1 --mode 1920x1080
randr --fb 4480x1200

I would like to have
left:1920x1080(nvidia-dvi-0), center:1680x1050(nvidia-dvi-1), right: 1920x1080(intel-vga-1 )

Thank you for your help

Re: 3 monitors 2 gpu (nvidia + intel i5)

How are you starting X ?

I'm not sure what the randr command is supposed to achieve, but 4480x1200 doesn't match the 3 monitors surface area.
5520 x 1080 should be correct size for all 3 monitors together.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)
