Ventilation louvers
should be positioned to allow good airflow while eliminating the possibility of liquids
or foreign objects reaching internal components (an internal baffle can prove
helpful). A good UPS with temperature monitoring is highly recommended. Depending
on the application, the external power supply cable, network cable, and (if necessary)
alarm cables may need to be armored.
15.3 Configure X for a Kiosk
Configuring X for a kiosk involves removing features to limit what the user can do.
The three main configuration entries for this can be placed in the ServerFlags
section:
Section "ServerFlags"
Option "DontZoom"
Option "DontZap"
Option "DontVTSwitch"
EndSection
This prevents the user from changing the display resolution, terminating the X
server, or switching virtual terminals.
During the development and testing of the kiosk, you may want to store the kiosk X
configuration in a separate file (such as /etc/X11/xorg.kiosk.conf) so that the default X
server retains its original configuration. To start X with the kiosk configuration, supply
the -config argument on the command line:
blue$ X -config /etc/X11/xorg.kiosk.conf
