在家目录下建立.gtkrc-2.0 文件，并且添加以下内容：
style "xfdesktop-icon-view"
{
XfdesktopIconView::label-alpha = 0
#设置alpha
base[NORMAL] = "#FFFFFF"
base[SELECTED] = "#FFFFFF"
base[ACTIVE] = "#FFFFFF"
fg[NORMAL] = "#000000"
fg[SELECTED] = "#000000"
fg[ACTIVE] = "#000000"
}
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"
