Screen Tearing on Intel Graphics with Dual Monitor Setup Nvidia and Intel

Ok i know there are alot answers regarding intel graphics or nvidia graphics screen tearing but i have scoured every thread i could find and here's what i came across (i am using ubuntu 20.04)

My Setup Nvidia Gtx 1050 ti running nvidia 470 latest stable driver running 1080p Monitor

Another monitor is connected through VGA in intel graphics running 1366x1768 both at 60 hertz

Initially both monitors had screen tearing, but i fixed the screen tearing for the nvidia monitor with

nvidia-settings --assign CurrentMetaMode="nvidia-auto-select @1920x1080 +0+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0, ForceCompositionPipeline=On, ForceFullCompositionPipeline=On, ForceCompositionPipeline = On}"

and adding this to startup apps, cause saving nvidia-settings to /etc/X11/xorg.conf disables intel graphics monitor

So now when nvidia tearing is fixed, intel tearing is still present, the answers i find that said to fix screen tearing is this

Section "Device"

   Identifier  "Intel Graphics"

   Driver      "intel"

   Option      "TearFree"    "true"

EndSection

and adding this to /etc/X11/xorg.conf.d/20-intel.conf which doesn't work in my case.

any suggestions what i should do ? this question have been asked on askubuntu few times before, but they don't seem to get answers. see this , and this also they have same problem as mine

also this is my xrandr output

After weeks of tinkering and trying to figure out what might be wrong
and after sancho.s ReinstateMonicaCellio's detailed answer and still not fixing the issue i got frustrated and gave up.And thought maybe two monitors connected with two different graphics is doomed with screen tearing on the intel side.

But i accidentally stumbled upon nvidia-prime, and started reading upon it, what i understood is, It let's either gpu render the other gpu monitor's screen. So nvidia can use its processing to render everything connected to intel side.

so the steps i used are

Step 1: enable nvidia force composition pipeline

you have to do it using startup scripts, other methods doesn't work, and don't try to save it to xorg.conf , if you enable from nvidia-settings it will disable the intel display on next reboot.

DO NOT DO THIS

i found this script that auto detects your screen configuration and enables nvidia force composition pipeline

nvidia-settings --assign CurrentMetaMode="$(nvidia-settings -q CurrentMetaMode -t|tr '

' ' '|sed -e 's/.*:: (.*)/1

/g' -e 's/}/, ForceCompositionPipeline = On}/g')" > /dev/null

But it needed some modification from my end, copy this part and run

"$(nvidia-settings -q CurrentMetaMode -t|tr '

' ' '|sed -e 's/.*:: (.*)/1

/g' -e 's/}/, ForceCompositionPipeline = On}/g')"

it will generate something like this

shantanu@shantanu-pc:~$ "$(nvidia-settings -q CurrentMetaMode -t|tr '

' ' '|sed -e 's/.*:: (.*)/1

/g' -e 's/}/, ForceCompositionPipeline = On}/g')"

DPY-1: nvidia-auto-select @1920x1080 +0+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0, ForceCompositionPipeline=On, ForceFullCompositionPipeline=On, ForceCompositionPipeline = On} : command not found

remove the DPY-1: and the : command not found parts

and modify the command with the generated values like this (Just replacing the edited value with the previously "inside the quotation command")

nvidia-settings --assign CurrentMetaMode="nvidia-auto-select @1920x1080 +0+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0, ForceCompositionPipeline=On, ForceFullCompositionPipeline=On, ForceCompositionPipeline = On}"

Step 2: the add it to your startup scripts

Step 3: install nvidia-prime

sudo apt install nvidia-prime

switch to nvidia using prime so all the redering is done by nvidia
intel screen will be rendered by nvidia too

sudo prime-select nvidia

This will effectively fix the screen tearing, only drawback is nvidia gpu usage will be higher cause it is doing rendering for two monitors, while intel just outputs it.

This was a long lasting issue on many threads, and maybe it will help somebody who is searching for help.
