You need to change gdm's config to remove the menu options. Open /etc/X11/gdm/gdm.conf in a text editor and find the [greeter] section. Make sure there is a line like this: [greeter] ... SystemMenu=false This removes the shutdown/reboot options from the log-in screen and the log-out dialog. Alternatively run gdmconfig and provide the root password, then uncheck the 'Show action menu' option on the security tab. To prevent users opening a terminal and running poweroff or reboot, delete or move these files: /etc/security/console.apps/poweroff /etc/security/console.apps/reboot If your machines use ACPI, you will also need to disable ACPI-driven shutdowns from the power button. On more to go now, to prevent someone switching to a virtual console and hitting ctrl-alt-del, we need to edit inittab. Find the line that looks like this: # Trap CTRL-ALT-DELETE ca::ctrlaltdel:/sbin/shutdown -t3 -r now And change it to read: # Disallow CTRL-ALT-DELETE ca::ctrlaltdel:/bin/echo "ctrl-alt-delete has been disabled" (You can use /bin/true, or /usr/bin/logger etc. here instead if you wish - just watch out if someone tries ctrl-alt-del before /usr is mounted :) Kind regards, > -- > Ben Steeves _ bcs@xxxxxxxxxx > The ASCII ribbon campaign ( ) ben.steeves@xxxxxxxxx > against HTML e-mail X GPG ID: 0xB3EBF1D9 > http://www.metacon.ca/bcs / \ Yahoo Messenger: ben_steeves > -- Bryn M.
