Setup survey kiosk
Arch system (manjaro). Display manager is LXDM and window manager is i3; browser is Surf.
php, see that they work. Do not forget to execute
mysql_secure_installation.Then install limesurvey by unzipping in apache www root. Then configure limesurvey by going to http://localhost/limesurvey/admin - you may be asked some sensible questions. Create your survey and obtain it's link. We presume there are only
kiosk users set tup on the system. For configuring your survey you can use any other browser - e.g. chrome or firefox. Surf by default gives only one window with no tabs and for my purposes I was very happy with that.
Now the kiosk bit:
For kiosk we want system to log in the
kiosk user automatically and stay just on one page (this is where our survey gets done and upon each submission presented afresh to users).
Create the file
Option "DontVTSwitch" "True"
Option "DontZap" "True"
This was the file I was worried about in respect to Wayland. I was confused. These settings get picked up just fine.
Configure LXDM via
/etc/lxdm/lxdm.conf. You need to uncomment or add the following.
Adjust i3 setup
All i3 configuration is done in
~/.config/i3/config. Most settings go well at the very start - so that you can comment them out quickly if you need to use i3 in normal mode.
set $mod Mod4
# shut down system with systemd/polkit (i.e. remains the only key combination that works)
bindsym Control+Shift+C exec /usr/bin/systemctl poweroff
# make surf start in fullscreen
for_window [class="Surf"] fullscreen
# execute surf in kiosk mode
exec /usr/bin/surf -K http://localhost/limesurvey/index.php/541114?lang=en
# use nitrogen for wallpaper if expecting at times to log in normally as well
exec --no-startup-id nitrogen --restore
Keep the screen on
So far so good from available kiosk guides, but not sufficient if you want to always keep the screen on. You need to disable display power management. When leaving work, you can always press that physical
Off button. You can control power management via
xset commands. Importantly - LXDM reads
~/.xprofile (not .xinputrc etc.) so this is where you want to put the commands to turn off all power saving for the display:
xset s 0 0 s noblank s noexpose &
xset -dpms &
Lock the system
Finally you may want to lock accounts to prevent other than autologin. To undo this you will use
passwd -u and to get to do that after this stage you will need to use single mode logon by appending
init=/etc/bash to grub kernel line at boot time. But for now in a root terminal you should execute:
passwd -l root
passwd -l kiosk
You can further proceed to secure
grub2 menus with password, if you wish. But your kiosk survey system is ready.
