Vamos a crear un documento con el nombre de .gtkrc-2.0 en nuestro directorio ~/home y pegaremos las siguientes lineas.
# Iconos transparentes
style "xfdesktop-icon-view" {
XfdesktopIconView::label-alpha = 20
XfdesktopIconView::selected-label-alpha = 100
XfdesktopIconView::ellipsize-icon-labels = 1
XfdesktopIconView::tooltip-size = 128
XfdesktopIconView::shadow-x-offset = 1
XfdesktopIconView::shadow-y-offset = 1
XfdesktopIconView::shadow-color = "#000000"
XfdesktopIconView::selected-shadow-x-offset = 2
XfdesktopIconView::selected-shadow-y-offset = 2
XfdesktopIconView::selected-shadow-color = "#000000"
XfdesktopIconView::cell-spacing = 6
XfdesktopIconView::cell-padding = 6
XfdesktopIconView::cell-text-width-proportion = 2.5
base[NORMAL] = "#000000"
base[SELECTED] = "#000000"
base[ACTIVE] = "#000000"
fg[NORMAL] = "#FFFFFF"
fg[SELECTED] = "#FFFFFF"
fg[ACTIVE] = "#FFFFFF"
}
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"
Si desean mas transparencia y mejor efecto en los iconos pueden probar este otro.
# Iconos transparentes
style "xfdesktop-icon-view" {
XfdesktopIconView::label-alpha = 0
XfdesktopIconView::selected-label-alpha = 100
XfdesktopIconVIew::ellipsize-icon-labels = 1
XfdesktopIconView::shadow-x-offset = 1
XfdesktopIconView::shadow-y-offset = 1
XfdesktopIconView::shadow-color = "#000000"
XfdesktopIconView::selected-shadow-x-offset = 1
XfdesktopIconView::selected-shadow-y-offset = 1
XfdesktopIconView::selected-shadow-color = "#000000"
XfdesktopIconView::cell-spacing = 0
XfdesktopIconView::cell-padding = 0
XfdesktopIconView::cell-text-width-proportion = 2
base[NORMAL] = "#3F6BA4"
base[SELECTED] = "#3F6BA4"
base[ACTIVE] = "#3F6BA4"
fg[NORMAL] = "#ffffff"
fg[SELECTED] = "#ffffff"
fg[ACTIVE] = "#ffffff"
}
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"
NOTA: Si al reiniciar el fondo de los iconos no es transparente reenombraremos el archivo .gtkrc-2.0 por .gtkrc.mine que como dije estara en el directorio de nuestro usuario ~/home y reiniciar. (Solo uno de los códigos que puse arriba es el que van a colocar).
