Be aware that LXDE is EOLed and pretty much has no future because of
being based on GTK2. The successor project, based on the Qt graphics
library instead -- where all the developer energy went -- is LXQt.

GTK2 has been, as to development, dead as a doornail since 2011. LXDE
is one of many projects who looked at the dismaying near-total rewrite
required for migrating to GTK3 (and GTK's increasing GNOME-centric
nature) and made the agonising decision to bail and migrated sideways to Qt.
