Por alguma razão desconhecida, esse tipo de aplicativo não dura muito e é quebrado em novas iterações do Ubuntu. O Gshutdown não funcionou para o Ubuntu 15.10 e não é muito conveniente baixar algumas centenas de MB de dependências para o aplicativo kwin. Pelo menos não para este tipo de aplicação.
Aqui está um pequeno script que eu escrevi que emite este problema e, sem dúvida, é uma escolha melhor. Porquê:
- é um script gráfico para que possa ser executado como aplicativo clássico
- como qualquer outro recurso de script pode ser ajustado de acordo com a preferência do usuário
- o código pode ser usado em várias distros e não é provável que mude em breve
- várias opções incluídas são descritas no script.

###########<<INFO
# This script is intended for use in various Linux distros. In order to use all available options install 'xprintidle' package. It is responsible for 'system idle' option,
# but the script will run without it as well. To install package on Debian-based distros execute: 'sudo apt-get install xprintidle' .
# Other packages used in script: zenity, notifyOSD, xdotool, wmctrl, play.
#
# Below INFO section there are some predefined variables. Their values can easily be customized by user.
#
# Some options available:
#
# -Select an action - the only option that must be selected, others can omit. The hibernation action is not visible by default, but it can be enabled. Use this at your own risk,
# it has not been tested. To enable hibernation uncomment two lines in 'case var1' statement and add |Hibernate option in zenity dialogs:
# --list-values='Shutdown|Restart|Hibernate|Suspend|Logout|Lock screen'. Alternative actions are commented and use them in case your distro doesn't support default ones.
#
# -Time from now; on user inactivity; at specific time and date - only one of these can be used at the same time. The accuracy for latter two is +-1 min.
#
# -Run custom command before action executes - BE CAREFULL !!! with this one. After confirmation dialog timeout, there is no turning back.
#
# -When selected application exit - clicking on this option new dialog will be presented with available options. Select action and preferred options (if any) and press OK.
# Then select the application by clicking on it.
#
# -Default - first time this option is activated it will open new dialog with available options. Select preferred options. They will be saved in 'default_conf_file'
# which is predefined as 'default_conf_file=~/.cache/Shutdown_dialog_conf_file.txt' The script will then execute !
# But on next run script will execute just by pressing 'default' button.
