Thank you!

Know that this solution is for.... 
Intel i915 onboard chip
The OP suggests creating a file named 
20-intel.conf  in the directory 
/usr/share/X11/xorg.conf.d
If you were to do this from the terminal; you could vi a new file, most likely needing sudo to do so... 
Code:
sudo vi /usr/share/X11/xorg.conf.d/20-intel.conf
then insert (press i ) and paste (right click) the following into that screen... 
Code:
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "sna"
   Option      "TearFree"    "true"
   Option      "DRI"    "3"
EndSection
then press... ESC followed by :wq  the :wq will write the file -- the :wq will display at the lower left corner - if in line with the text you need to delete the :wq and ESC prior..
then as instructed ... reboot.. 
Again, this is for the i915 chip - the instruction may not work for you if not the same, though it may or it may not display all.. 
* I would create a backup as a safety line... 
And know how to access the TTY if you boot to blank screen then it'll be command lines to undo...
