I know the issue with screen tearing on an onboard Intel card has been asked before, not none of the solutions offered has worked for me.
I am using both of my graphics card with 2 screens connected to my Nvidia card and a television connected to my Intel card. The 3 screen setup works fine, but there´s tearing on all screens.
The nvidia tearing is fixed by forcing full composition through the nvidia settings tool (though I have to do it again every time I reboot.
I cannot fix the Intel tearing though.
The solution that is usually offered is creating an intel conf file in the Xorg folder (ie. /etc/X11/xorg.conf.d/20-intel.conf or /usr/share/X11/xorg.conf.d/20-intel.conf), but doing that results in Xorg not working on boot.
Any other solutions? Thanks.
