Screen Tearing Fedora 28 Gnome on Xorg

image description

I had spent days for solution, but nothing work so far, please help!
Things I had tried:

/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"
EndSection

/etc/X11/xorg.conf.d/20-modesetting.conf
Section "Device"
Identifier "Intel Graphics"
Driver "modesetting"
Option "AccelMethod" "glamor"
Option "DRI" "3"
EndSection

(both of these caused Xorg failed to boot...)
