[SOLVED]urxvt can't set the background after using slim as DM

Question

Yesterday, I changed lxdm to slim,and then everything went well,except urxvt.Though I think this should have nothing to do with the urxvt's problem.
urxvt only has a white background while my setting is 0000/0000/0000/cccc,even I attempted to comment all options relating to colors,but it doesn't work.until I remove the .Xresources file, urxvt has a black background.
I also attempted to start from startx and other ways, but it didn't work.I have a transparent black interface before,and now it is dazzling white.how could i can resume it.
My DE is kde4.
Here is my .xinitrc
export GTK_IM_MOUDLE=fcitx
export QT_IM_MOUDLE=fcitx
export XMODIFIERS=@im=fcitx
exec startkde

To add to what sonoran posted above, you need to have xrdb load the settings in your ~/.Xresources.  When you use a DE, there are quite a few things that it might do for you depending on the existence (or absence) of a give configuration file. 
I have no idea what things are specific to each DE, but I know that the Slim login manager is extremely simple and lightweight and does very little (if anything) automagically for you.  A good example of automagic coming from some of the display manager part of things is the locale settings.  In particular, they implement their own ways of handling setting your keyboard layout and language.  So going if you were to go from GDM to Slim, you would suddenly have the stuff in /etc/X11/xorg.conf.d honored, whereas in GDM, you would either have to use gconf or use setxkbmap at some point.
