I am on Ubuntu 18.04 LTS. As a unity user I am facing a big difference with gnome as notifications are showed up at the top center. It is annoying while dealing with specially browser tabs. I searched the Internet and found this, but it did not work as described. Can someone help me with this?

  • Could you expand a bit more on "did not work as described"? At which step is it failing (extension installation issue or installs fine, but doesn't work or something else)? That extension works fine for me.

  • @pomsky Installation seems OK with no errors, but I cannot find it in gnome tweak tool.. Am I wrong? May 12, 2018 at 12:58
  • @pomsky yes, it does not show up.. May 12, 2018 at 13:00
  • @pomsky it says "GNOME Shell Extensions cannot list your installed extensions." May 12, 2018 at 13:05

    Just curious why rather than struggling with Gnome's differences over Unity you don't just use Unity in the first place? That's what I did in 18.04 until I'm ready to learn Gnome. May 12, 2018 at 15:53

To install the Panel OSD extension (as suggested in the external link you've mentioned) properly first install the chrome-gnome-shell by running

sudo apt install chrome-gnome-shell

Then go https://extensions.gnome.org/ using Firefox or Google Chrome. The webpage should ask you to install a browser add-on/extension, install it.

Then go to the extension's webpage. You'll find a toggle button. Turn it on.

Once the installation is finished, you'll be able to change the preferences of the extension using (GNOME) Tweaks.
