How to enable screen brightness and volume control in kiosk mode

I created a new user called “kiosk” on my machine. I set it up to load a specific web page in Google Chrome fullscreen kiosk mode. This works fine, but this issue I am having is that when I log in to the kiosk user in kiosk mode, I have no control over screen brightness or audio volume. If I log in as the kiosk user in Lubuntu mode (by clicking the icon near the upper right corner at the login screen) both of these work fine.

How do I set it up so both of these work in kiosk mode?

Enable fractional scaling for display in ubuntu 19.04

I understand 19.04 enables experimental fractional scaling from a couple of resources

  • https://www.omgubuntu.co.uk/2018/11/ubuntu-19-04-release-features
  • https://www.linuxuprising.com/2019/04/how-to-enable-hidpi-fractional-scaling.html
  • https://www.reddit.com/r/Ubuntu/comments/b1y2uw/fractional_scaling_1904_xorg/

And others for older Ubuntu versions:

  • Enable fractional scaling for Ubuntu 18.04

However, when I enable the feature as presented, I get an error that the setting isn’t saved:

~$   gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']" GLib-GIO-Message: 12:22:36.852: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications. 

Part of the instructions require rebooting to even get the menu to come up in display. How can I enable the ability to enable this setting successfully?

Enable packet filter firewall (pfctl -Ef) temporarily stops all network connection

I’ve noticed that when re-setting my firewall with a new set of rules, all network communication completely stops for a short time, until it regains with the new set of rules.

In fact, it also occurs when I start firewall after it was previously closed or when it switch from enable to disable state.

Why does PacketFiler temporarily halt connection every time it changes state (using pfctl -Ef or pfctl -d) ?

I created a file type and an interpreter for the file type. I want to enable the interpreter run the file type once the file type is doublr clicked

I created a file type called oox, I created an interpreter for the file type. I used to do all of the task python.

I compiled the source code with pyinstaller to get the exe of the interpreter, the exe works perfectly; now i want to make the program to run the file type without asking user for input, but rather; through double clicking on the oox file.

What do i need to add to the source code to perform the task?.

The first set of lines after the import statements for the interpreter are below:

print(‘Please input the .oox file:’) doc = input() #This is the oox file
