How to uninstall an Extension, namely Background Logo

I had ever used Fedora from Spins,(KDE & Cinnamon), and Workstation(GNOME + a dozen of GNOME Shell Extension) for nearly 3 years.
After I have installed Fedora 34 Beta and I have uninstalled all GNOME Shell Extensions, especially Dash to Panel. I found that all inconveniences were gone for I am using the external monitor and I could not enter the new filename to be saved easily before.
Since the first day of Fedora 34 Beta announcement until today, I have been practicing working with the Workstation Edition DE. And finally found that it works so fast and I will never think of the desktop like the one I had used for over 30 years.

But I could not uninstall an Extension, namely Background Logo. Can you please teach me ? And is it possible to insert into the background by default ?

If you are using gnome tweaks to disable the extension then sometimes it fails to disable the extension. So the alternative is the official extensions app provided by the GNOME team. You can either install it from the default repos or flathub and there you can turn off the background logo extension or remove it altogether.
https://flathub.org/apps/details/org.gnome.Extensions

You’d have to manually add that to your backgrounds using an image editor like GNU Image Manipulation Program.

Gnome extensions can either be system extensions or user extensions—if you see your extensions in your browser, it will tell you which are system extensions:

https://extensions.gnome.org/local/

System extensions, as the name suggests, are installed system-wide and for all users. As @yasharjit noted you can disable them for your user, but only an administrator can uninstall them.

To uninstall the background logo extension, please use:

sudo dnf remove gnome-shell-extension-background-logo

Not sure what you mean here—the extension overlays the Fedora logo over the background image. It does not modify the image itself. Are you asking if the background image can be modified to include the logo in it?

I’ve not uninstalled Background Logo.
There is no Fedora Logo on background image on either notebook screen or external monitor yet.



Your screenshot shows the the extension is disabled—so no logo will be shown. Have you enabled it yet? (Click the switch to toggle it from “OFF” to “ON”)

I switched it on but Fedora logo did not appear, so I have uninstalled it and all extensions already.
I think there might be something strange in my computer during upgrading to either Fedora 34 Beta or Fedora 34 (Workstation Edition) x86_64(today).
Is there a way to check it up to see if Fedora 34 is fine on my computer ?

You may need to log out and back in to have extensions activated. Please reinstall it, then enable it, and log out and back in. Then, please change your background to something that’s not blue based so you can see the logo. Since it’s blue, and quite light, it isn’t always obvious:

Visible here:

Not so much here (but it’s there!)

What makes you say this? Are you experiencing other issues?

  1. I have installed Extensions from Software app again but Extensions mentioned that it’s incompatible.
  2. I have 2 notebooks.
    Notebook no. 1 (of this question) has been upgraded from Fedora 33 Workstation to Fedora 34 Beta and Fedora 34 Workstation(today) respectively.
    Notebook no.2 has been upgraded from Fedora 33 Workstation to Fedora 34 Workstation(today). But notebook no. 2 has the logo.

That screenshot doesn’t show the “Software App”. That’s the gnome-shell extensions website. They may not have released the latest version there yet. Please install it from the Fedora repositories:

sudo dnf install gnome-shell-extension-background-logo

I cannot say why one system has it and the other doesn’t—they’re not clones of each other so it’s not necessary that you’ll get the same set of tools on both.

Your second screenshot also shows that you don’t have the necessary browser extension installed there, but the first screenshot doesn’t show this. This indicates the second system is not identical to the first.

Here’s what you need to do. It works, so please follow the steps carefully.

  • install the package using dnf using the command given above
  • log out and back in
  • go to the extensions application and enable the extension
  • set a different background so you can see if it works

If this doesn’t work, please specify exactly what step you got an error at, otherwise it’s very hard to say what’s going wrong.

Thank you so much, now I have the logo already.
And one more last question about Extensions please.
Is User Themes a must ? If not, can you please teach me to uninstall it ?

You can remove it, but because gnome-tweaks depends on it, it’ll try to remove that too:

$ sudo dnf remove gnome-shell-extension-user-theme

I’d let it be. It won’t affect your system at all.

I’d better keep it.
