NVIDIA screen tearing fixed by logging out

I have an Optimus Laptop with a UHD 630 and a NVIDIA 1050 TI. I recently installed optimus-manager, which works great. However if I set the boot process to go right into NVIDIA card, the screen tears at the pointer until I log out and in. I am using Cinnamon. I am guessing something is done by logging in that is skipped by just booting up. Here are outputs (in nvidia mode) one could need, If I miss any I will add as soon as I can.

Hello @Jack1221 :wink:

Could you also post your xorg confs?

for x in /etc/X11/xorg.conf.d/*.conf; do echo -e "---$x---\n\n $(cat $x)\n\n"; done

Possible you need to add something like that:

Option "metamodes" "HDMI-0: nvidia-auto-select +0+0 {ForceCompositionPipeline=On}

(sure you have to replace HDMI-0 with your output)

I added that line to /etc/X11/xorg.conf.d/10-optimus-manager.conf, replacing HDMI 0. Is there any way to verify if it is active? I also added my config files (before edit) to the original post.

Edit: It seems to be working, thank you!

At the Xorg log:

grep "Option \"metamodes\"" /var/log/Xorg.0.log 

Nice :+1:
