| + | ===== Setting up the Kiosk function... ===== | ||
| + | |||
| + | With X up and running, and the filesystem back in read-only mode, make sure the non-root user crated during install is available for use, by setting up the home directory: | ||
| + | |||
| + | <code> | ||
| + | mkdir /home/kitteh | ||
| + | chown kitteh.kittteh /home/kitteh | ||
| + | </code> | ||
| + | |||
| + | Now, either switch to a different VT, or log out root. Log in as the non-root user created during install, create a simple ~/.xinitrc: | ||
| + | |||
| + | <code> | ||
| + | # File: /home/kitteh/.xinitrc | ||
| + | xterm & | ||
| + | blackbox | ||
| + | </code> | ||
| + | |||
| + | Start up X: | ||
| + | |||
| + | <code> | ||
| + | startx | ||
| + | </code> | ||
| + | |||
| + | Now, start up iceweasel (yeah, firefox is not called firefox, but iceweasel on Debian, due to licensing issues). Install the Autohide extension from http://www.krickelkrackel.de/autohide/, and configure it for the local user. By enabling this extension, and exiting iceweasel while it is displayed fullscreen, iceweasel will "always" start in full-screen mode. | ||
| + | |||
| + | After setting iceweasel up, update the .xinitrc: | ||
| + | |||
| + | <code> | ||
| + | # File: /home/kitteh/.xinitrc | ||
| + | xsetroot -solid white & | ||
| + | xset -dpms s off & | ||
| + | unclutter & | ||
| + | xterm -iconic & | ||
| + | iceweasel http://the.url.of.the.kiosk.example.com & | ||
| + | blackbox | ||
| + | </code> | ||
| + | |||
| + | After this, exit X11, test that it works OK, and exit the non-root login completely. | ||
| + | |||
| + | Now, we need to retain the settings made from boot to boot. /home is mounted as a tmpfs, so we need to clone the kitteh | ||
| + | home directory somewhere else on the file system, and push it back in place on boot. Log in as root.. | ||
| + | |||
| + | <code> | ||
| + | rw | ||
| + | cp -pRv /home/kitteh /usr/local/kitteh | ||
| + | </code> | ||
| + | |||
| + | Add the following to /etc/rc.local to clone the saved homedir content on boot: | ||
| + | <code> | ||
| + | cp -R /usr/local/kitteh /home/kitteh | ||
| + | chown -R kitteh.kitteh /home/kitteh | ||
| + | </code> | ||
| + | |||
| + | I have opted to force X to start on boot by running it from /etc/rc.local as well, by adding this line | ||
| + | just above "exit 0": | ||
| + | |||
| + | <code> | ||
| + | su -c "startx" kitteh | ||
| + | </code> | ||
| + | |||
| + | Now, X will normally not start unless the user starting it is also controlling the console. As I am starting X from an rc-script, that is not the case. So, to allow rc.local starting X as the user "kitteh", put the following content in | ||
| + | /etc/X11/Xwrapper.config | ||
| + | |||
| + | <code> | ||
| + | # Keeping the old setting as a comment, for clarity... | ||
| + | # allowed_users=console | ||
| + | # | ||
| + | # This is not really seen as "safe", but in our case, it is needed.. | ||
| + | allowed_users=anybody | ||
| + | # | ||
| + | # Niceness value? Nah.... | ||
| + | nice_value=0 | ||
| + | </code> | ||
| + | |||
| + | That should really be enough for starters. Close everything up, set the file system as read only again, and reboot. | ||
| + | |||
| + | <code> | ||
| + | ro | ||
| + | reboot | ||
| </code> | </code> | ||
