The following page is only valid since Linutop OS 3.0.2. If you are using a previous release, you should upgrade your system. The old documentation is still available.
Setting the Lock mode up
Setting up the system to use the lock mode requires 3 steps.
Switch to a persistent system using the configuration tool: this can be done in the Advanced tab, in the Data persistence sub-section, as show on the screenshot below. Once you have set this, you need to reboot your Linutop.
Once you have rebooted, you may want to tweak the settings of the desktop:
- add some applications
- the desktop wallpaper
- the panel
- the autostarted applications
- the external devices management
Once you are done, enable the lock mode in the Linutop configuration tool, in the Security tab shown on the screenshot below by checking the Use the Linutop lock checkbox.
You will be asked to choose a password to secure the system. This password will be asked every time you carry out a task which requires administrator privileges.
Reboot the system to launch the Linutop in Lock mode.
Disabling the Lock mode
Open the Linutop configuration tool and uncheck the checkbox Use the Linutop lock in the Security tab. The password you set before is required to perform those actions, so don't forget it!
Backups and restorationbackup on an USB key. This backup can be used to restore your Linutop's internal memory if something wrong happens.
If you've lost your 'linutop' password, you'll be locked. A solution to restore the system on the internal disk without erasing the system is to boot on a backup key, and to copy the file /cdrom/syslinux.cfg to the root of the hard drive. In a terminal this can be done with:
sudo mount /dev/hda1 /mnt # this makes the device writable sudo cp /cdrom/syslinux.cfg /mnt/ # copy the file sudo umount /mnt # cleanup
You should be able to reboot in the default Linutop mode.
Prevent users from modifying the system on a running Linutop
The Kiosk mode can be enabled in the Security tab of the Linutop configuration tool, by checking the "Activate the xfce kiosk mode" checkbox. The system needs to be rebooted for this to take effect.
You can also remove the "Shutdown" and "Reboot" options in the login manager by opening Login Window item of the System menu and by unchecking the Show actions menu checkbox in the second tab of this dialog.
About the Lock mode
This means that the modifications that you need to do on the system (adding a new software, a driver, changing the wallpaper or the icon theme...) have to be done in persistent mode and before switching to the lock mode.
