  • 772

A script that requires root privileges needs to be executed when a non-root privileged user signs in/out. How do I handle this?

scripts root users

  1. Use the PAM session hooks module.

  2. lightdm, the display manager in Ubuntu allows running session setup scripts as root if you add appropriate entry to /etc/lightdm/lightdm.conf file (Note, that this file doesn't exist as of 14.04, you have to manually create it).

    Example of how it might look like

    [SeatDefaults]
# session-setup-script = Script to run when starting a user session (runs as root)
session-setup-script=/opt/myscripts/print_hello.sh
# session-cleanup-script = Script to run when quitting a user session (runs as root)
session-cleanup-script=/opt/myscripts/print_hello.sh
