I need option backingstore for my X server.
I'm running Fedora 15 LXDE spin.
as we all know, there's no xorg.conf file (where one could put "Option Backingstore" into the "Device" section).
I tried adding +bs in /etc/lxde/lxde.conf at
arg=/usr/bin/X +bs ....
then logout/login or Ctrl-Alt-Backspace or sudo lxde stop / sudo lxde start.
still there seems to be no Backingstore.
