Unable to resize window

Hello,

So, a few clarifications since you say you're just starting out.

There are different Linux distributions, including Ubuntu. It's a user-friendly distribution, so it's a reasonable choice for someone who is just starting. Normally, the differences between Ubuntu and Windows XP will be relatively minor if I refer to the use cases you mentioned. It’s mainly the start menu, the way to install or update your system that will be different. Moreover, many software applications (Firefox, Thunderbird, Chrome/Chromium, GIMP, LibreOffice) exist on both Windows and Linux, so if you're used to using free software, you shouldn't feel too out of place.

• Then you mention a window, but I have the impression you are referring to your browser instead. Can you clarify which software you are talking about (Firefox?) and possibly add a screenshot to illustrate your issue?
• Which version of Ubuntu are you using? (please refer to the content of the file

  /etc/apt/sources

  )
• What version of your browser?

Good luck!

Hello,
Sorry for the delay, I was absent. I have Linux Mint 19.3 Tricia - Firefox. The problem has been solved (partly), it was about reducing the windows of several visited sites on the taskbar to be able to switch from one to another quickly.
I have never had any digital training. I have no problem navigating the web, using email, organizing files, making some online purchases, creating slide shows with animations and sounds, checking my bank account, etc... but as soon as we tackle the "hard stuff," it’s a different story.
For example: (report us the content of the file /etc/apt/sources), it's Chinese to me!

Thanks again for taking the time to respond.

Hello,

Regarding having multiple sites and switching quickly from one to another:

• In general, it is not necessary to open a browser for each site you visit.
• Any modern browser (firefox, chromium) allows you to open multiple sites at once (one per tab) and to switch easily from one to the other by clicking on the appropriate tab. To open a link in a new tab, you can right-click on the link, open in a new tab (or click on the link while holding down the Ctrl key).
• It is possible to drag your tabs to reorganize them, or even detach them into a new browser window.
• Depending on the graphical environment you are using and how your taskbar is configured, you may have an icon for each application (for example, a firefox button that groups all open firefox windows), or one for each window (so potentially, several instances of firefox if multiple are open).

Then regarding reporting the contents of the file

/etc/apt/sources.list

:

When you are on Windows, the Explorer or My Computer allows you to navigate through your hard drive. Your hard drive corresponds to a drive (c:) where folders, including your personal folder and files, are located. A drive is typically created for each disk connected to your computer (CD, DVD, USB stick) (more precisely, for each partition).

On Linux, all these files are also organized in a tree structure, but it is different from what you find on Windows. Without going into the details of the FHS which describes this organization, at your level you need to remember two things:

• There is no notion of a drive. There is only a directory tree, where all the files you can interact with are gathered, regardless of the drive they are physically stored on.
• In

  /

  there is a folder

  home

  , noted as

  /home

  , which contains the personal directories of users and their profiles. It is the equivalent of

  c:\My Documents

  on Windows.

• /etc

  contains configuration for system applications.

• /media

  allows you to access your devices (USB stick, CD, DVD, camera...).
• Everything else you can ignore at this stage.

So when I ask you to report the contents of /etc/apt/sources.list, this is what it means:
1) Open a file explorer (e.g. nautilus or dolphin)
2) Go to the root folder

/

, then into

etc

, and then into

apt

(so you will be in

/etc/apt

)
3) Open

sources.list

(thus

/etc/apt/sources.list

) by double-clicking on it. As its name indicates, it is a configuration file (etc), linked to your package manager (apt). The package manager on Linux is the equivalent of the PlayStore/AppleStore on a smartphone, a place where you can install/uninstall/update your applications. Traditionally, we go through the software center for these tasks, but this software relies in the background on the configuration file

/etc/apt/sources.list

to know where to retrieve applications. This file will allow me to know what version of Ubuntu you are using.
4) Select (ctrl a) Copy (ctrl c) the content of

/etc/apt/sources.list

and paste it into your message (ctrl v).

Feel free to also let me know if you still have a problem to solve and if so, which one.

Thank you very much for this "mini course" that helped me a lot. I think I'm good now.

I would like to have your skills, but at 78 years old, I doubt I will become a "geek"!
I have other priorities: to last...
