Howto: Remove the brown background color during login

You may have noticed that the background color turns light brown for a second before and after login. If you had, then you probably noticed it because you changed the default GDM login or the background in gnome.
Turns out the program is straight in the login manager. Specifically, in the file /etc/gdm/PreSession/Default. Thankfully, it’s easy to fix with a text editor.

So from the command line type:

# gksudo gedit /etc/gdm/PreSession/Default

Scroll down to:

—————————–
# Default value
if [ “x$BACKCOLOR” = “x” ]; then
BACKCOLOR=”#dab082″
fi

“$XSETROOT” -cursor_name left_ptr -solid “$BACKCOLOR”
fi

exit 0
————————–

then change

BACKCOLOR=”#dab082″

to any hexcolor you prefer, for instance

BACKCOLOR=”#000000”
