Bug description:
[Impact]
lightdm-session runs xrdb for .Xresources file with the -nocpp option
(Line 37 and 43), which prevents the xrdb from preprocessing the
.Xresources file. Many configurations like the popular solarized color
theme (https://github.com/solarized/xresources/blob/master/solarized)
use this and you find some complaints about in on the internet

http://superuser.com/questions/655857/urxvt-uses-pink-instead-of-solarized-until-i-run-xrdb-xresources/656213
I don't see a reason for not using the preprocessor and so did the
editor of Xsession (the option is not used in
/etc/X11/Xsession.d/30x11-common_xresources)
[Test Case]
- Install solarized theme
https://github.com/solarized/xresources/blob/master/solarized
- Load default Xresources file (xrdb < .XDefaults )
- Now every macro supported by CPP will not work.
[Regression Potential]
* No regression potential advised, small (0.001%) load average increase
on startup time because of enabling Cpp.
[Solution]
Backport default wily session to older releases.
