Ainda não estou familiarizado com upstart . Quando eu inicio o KDE com minha própria conta upstart inicia muitos serviços, tanto quanto eu entendo. Mas eu tenho alguns outros usuários que eu deixo usar openbox porque eu quero que eles tenham um sistema mínimo com apenas um navegador. Então, depois que eles fazem login, digamos tty5 , eles são executados:
$ ps aux | grep ^lightUser
lightUser 7430 0.0 0.0 41092 7432 tty5 S 01:06 0:00 -bash
lightUser 10038 0.0 0.0 34916 2596 tty5 R+ 01:19 0:00 ps aux
lightUser 10039 0.0 0.0 28216 796 tty5 S+ 01:19 0:00 grep --color=auto ^lightUser
Depois de iniciar a sessão gráfica, aparecem miríades de serviços:

(Por algum motivo, quero que eles sejam executados com Xephyr , blackbox e openbox ).
Como posso impedir que todos os serviços redundantes sejam inúteis? Eu suponho que eles não precisam de nada que contenha *bus* , notify , screensaver , launcher , zeitgeist , pulseaudio , nm-applet , etc ....
Obrigado!
PS: o lightUser ' ~/.Xsession é:
Xephyr -fullscreen -screen 1920x1200 :11 &
exec blackbox &
sleep 4
DISPLAY=:11 /usr/bin/openbox-session
Além disso:
$ lsb_release -d
