Porteus Kiosk 4.9.0 released, lightweight Linux operating system

2 min read

Porteus Kiosk is a lightweight Linux operating system which has been restricted to allow only use of the web browser. Furthermore, the browser has been locked down to prevent users from tampering with settings or downloading and installing software. When the kiosk boots it automatically opens Firefox or Google Chrome browser to your chosen home page. The history is not kept, no passwords are saved, and many menu items have been disabled for total security. When the browser is restarted, all caches are cleared and it reopens automatically with a clean session to ensure no trace of history is left.

Porteus Kiosk is a full operating system which replaces Windows or any other OS during installation. While evaluating our product we recommend the installation on removable devices or in a virtual environment. When our system goes into production we strongly advise to install it on a PC hard drive.

Porteus Kiosk 4.9.0 released.



  • Added support for setting default zoom level in the Firefox and Chrome browsers.
  • Session idle function can lock the session instead of restarting it.
  • Its possible to select large mouse cursors theme for the system.
  • Screen locking button can be also present in the ‘shutdown menu’ if its enabled in the kiosk config.
  • Remote config name is displayed in the Administration Panel of Porteus Kiosk Server so its easier to determine which kiosks are pointed to which config.
  • Its possible to have the bookmarks toolbar enabled in the Firefox browser even when the rest of the navigation bar is disabled (kiosk works in fullscreen mode except for bookmarks toolbar at the top).
  • Upgraded GRUB bootloader to latest version from git. This was necessary to boot some CoffeLake and GeminiLake systems which supports EFI firmware only.
  • Forced screen resolution on the framebuffer level allows the kiosk to work in ‘FullHD’ mode in Hyper-V virtual machines.
  • Other bugfixes and improvements.
