Missing settings of online accounts in Ubuntu 18.04 with GNOME 3.28.2

I recently noticed that my system is missing online account settings.

Enter the image description here

I'm using Ubuntu 18.04.4 LTS with GNOME 3.28.2.

I can only view full setups with the terminal command:

env XDG_CURRENT_DESKTOP=GNOME gnome-control-center

with root rights (with sudo).

I tried to reinstall gnome-control-center or put the exec command env XDG_CURRENT_DESKTOP = GNOME gnome-control-center in the .desktop file. The result remains the same.

What is wrong?

Settings – Can I connect to the surveillance camera remotely?

To use the IP camera, you need to use the app on your phone. When you set up the camera, connect to it on your phone. However, if you need to give someone access to this camera, you can import settings and send them to another person (in another city) so that they can connect to this camera.

Probably it depends on the camera type, what about the EZVIZ C6CN 1080p Wi / Fi security camera for indoor and outdoor use?

Settings – Portable input device, setup best practices

We are working on a mobile 3D scanning device. The device is a small handheld device the size of a GoPro camera. The device has no display or other controls. The idea is that the user either connects the device to a computer / smartphone, sets the desired parameters and then walks around the object with the scanner aimed at the object.

Technically speaking, both Bluetooth and WiFi interfaces are available on the device. What are some best practices / examples of the process of connecting the computer / smartphone to the device?

Our previous ideas are:

  • Add a button to the device to put it in "Bluetooth pairing mode". The user pairs the device via the Bluetooth menu on the computer. Then he downloads our app and runs it to set it up. All subsequent communication runs via Bluetooth. (Like most bluetooth headsets)

  • When started, the device provides a WiFi network, the user connects to this network and then opens a website in the browser. The website is operated by the device and enables direct configuration. (Like some printers)

  • The user downloads our app, which then tries to establish a Wi-Fi direct (not too familiar with this technology) with the device. (I'm not sure if something like that is used)

  • The user downloads our app, which prompts the user to connect the device with a cable. After connecting, we either automatically set up the Bluetooth connection or allow the user to set up their WiFi credentials for the device at home. (Apple Magic Keyboard does that)

I would appreciate advice on this.

App to lock other apps and system settings

I'm looking for an app that

  • locks all other apps that I select (with lock I mean that no settings of these apps are changed or even opened), including the system settings (so that e.g. the system time cannot be changed or other apps are not set up)
  • is protected by a PIN or password, whereby the PIN or password can be of any length.

Can you please tell me if there is such an app? I have a non-rooted Android 9 phone.

sharepoint online – Is there a way to move files / folders from one site to another and have the exact permission as the source (migrate the related security settings).

I have a new project to move files from multiple modern SharePoint team sites to a single SharePoint online document library. My main concern is how we can keep permissions on the files / folders. Just like any third-party tool or a created tool. in the approach to support such a migration?

We just have to migrate files and support this scenario: –
1. Suppose SiteA and all folders inherit their permission from SiteA >> and we migrate the files / folders to SiteB >>. Then we also need the SharePoint groups from SiteA so that they can be migrated so that the migrated documents have the correct authorization. The source documents .. or any migration tool migrate the files / folders to SiteB and determine that they have their authorization from SiteB inherit. In this case the permission setting for the migrated files / folders will be lost (since SiteA and SiteB are different permission settings ..)?

Thank you very much

Multiple monitors display settings cannot be reset

I'm on Windows 10. Sometimes I connect my TV to my desktop to watch shows online from my couch. I connected the HDMI to my desktop and the screen was mirrored but nothing appeared on the TV. When I tried to fix bugs, I pressed Show on Monitor 2 and the image was moved from my main monitor to my TV, which is still blank. So when I connect to my TV, I lose all the pictures. I can only reset this setting when the HDMI is connected, but then I cannot see.

How can I reset all display settings to fix the original problem?

Mobile – Should I keep my password change section in the profile change area or settings?

I've seen some mobile apps keep the password change section separate from the profile edit screen (e.g. Instagram), but others only on the profile edit screen.

I personally am used to looking for the settings icon whenever I want to change my password. However, since my app isn't really that big and doesn't have much to do, I should just remove the settings and change the password in the editing profile.

My app currently has this type of structure:

My profile has the option to edit the profile.
