How can I reconfigure TLXOS while an app is running / what are the keyboard shortcuts?


See for more information on how to escape from a running fullscreen application.

When the local window manager has keyboard focus - which is any time that a fullscreen application does not have focus - the following keyboard shortcuts can be used:

  • <Ctrl><Alt>c starts the local configuration tool, allowing you to reconfigure TLXOS.
  • <Ctrl><Alt>i pops up dialog windows to indicate the display number than TLXOS has assigned to each monitor.  This will not be meaningful unless you are using an "Extend desktop" display layout, because in Clone mode the same thing is shown on every monitor.
  • <Ctrl><Alt>r will reset to defaults if this sequence is entered twice within two seconds.  "Defaults" means ThinLinx-provided ("factory") defaults unless a TMS administrator has defined a custom reset state.  Resetting to defaults will undo all post-install customization (currently including installed files such as SSH keys and CA certificates) except for basic configuration data, which in the "factory defaults" case means the license file and very little else.
  • <Ctrl><Alt>s starts a dialog to initiate session shadowing.  Under normal circumstances, TLXOS requires that the end-user initiate any such a connection to ensure that they have consented to this.  See for more information.
  • <Ctrl><Alt>t starts an unprivileged interactive terminal (shell/xterm) window.  If a Restricted Feature Password has been set, you will need to enter that before the window is started.  Please note that there is no way that you can assume superuser privilege in this window (there is no root/sudo password) - do to that, you must establish an SSH key trust and SSH to the device as root (see
  • <Ctrl><Alt>v starts a GUI volume control (alsamixer).  This is probably only useful if you are using USB audio on a Raspberry Pi - in other cases, using the audio volume slider in TMS or Tlxconfig should be sufficient.

In addition, the following XFWM4 window manager shortcuts can be used:

  • <Alt><F4> close current window
  • <Alt><F7> move current window
  • <Alt><F8> resize current window
  • <Alt><F9> minimize (hide) current window
  • <Alt><F10> maximize current window
  • <Alt><F11> fullscreen (maximize without WM decorations) window
  • <Alt><Space> pop up WM menu on current window
  • <Alt><Tab> switch window (cycle forward)
  • <Ctrl><Alt>d show desktop (iconify everything)
  • <Shift><Alt<Tab> switch window (cycle backward)
  • <Shift><Alt><PgDown> lower window
