Here I'm just showing the terminal command-line version of UFW which, again, will set the rules as global which isn't a problem if the computer isn't ever connected to a different style network. This isn't a problem if the computer OpenLP is running on, whether it's a desktop or laptop, never moves to another network.

It also allows you to easily delete a rule in case you create a wrong rule and allows you to select different profiles, especially if the computer OpenLP is on is a laptop and used to connect to different style networks (Public, Office, and Home being the defaults). If you just need to get this to work using the GUI (GUFW) is fine though and better if you don't know what you're doing. UFW has a graphic user interface (GUI) component but I personally find it easier to use the command line in a terminal window, 1 caveat being rules that are added in terminal on the commandline will be global to all profiles shown in the UFW GUI (GUFW) and aren't editable in GUFW and rules created in GUFW aren't viewable in the terminal via the ufw command. Some Debian varieties like Ubuntu and Linux Mint use UFW (Uncomplicated Firewall) which is a front-end for netfilter/iptables (you can perform a web search on it's usage). Or if you have OpenLP on a Linux computer then, on the Linux machine, you'll need to either disable the firewall (not recommended at all unless you know what you're doing) or add the rule that allows traffic into port 4316. If you are using a different type of display just find out the resolution an example would be a 720p display so that would be 1280x720, and calculate to center using my above steps. To make sure the box is perfectly center I take 960-400 which equals 560, and that how I obtained that number above. My text box's width is 800 and half of that is 400. The center of the width is 1920 divided by 2 so 960. To make sure my text box was 'centered', I had to do a little math.Ī 1920x1080 display or 1080p display means it's a rectangle with a width (X axis) of 1920px and a height (Y axis ) of 1080px. To have the text shown at the bottom center of the screen I set the following dimensions:

If your display is bigger or smaller you'll have to adjust the dimensions. Important Note: This is configured for a display of 1920x1080. This is the most important part as it will determine the location of where your box of text will display on the screen.
