Системное меню и настольный щелчок правой кнопкой не появляются в Gnome3

Потрясающий сценарий оболочки, записанный некоторое время назад другом: livre.

#---------------
# A parametrized replacement for psnup -2 using pstops.
#
# The script computes bounding boxes using gs and deduces optimized reductions
# on two pages per sheet with given margins or scaling. Pages can be arranged
# for various kinds of folding or binding.
#---------------
# Requires: gs, bc, pstops, psbook, pdftops
#---------------
