grrr, if you write that + in there, I will happily set you on the ignore list. Please think(!) when you do something. The "+" is from the patch as ... + means: add line - means: remove line.
On a normal Ubuntu system it could also be in /etc/lightdm/ligthdm.conf.d/10-ubuntu-something. Just find the Seat Defaults and write that line under it (without (!) the +) ... you need of course to reboot / restart lightdm and verify Xorg.0.log to have BackingStore disabled.
Btw. take care with your mailserver, if you already fail at patching / editing a single text file.
