Dash to Dock doesn't disable even uninstalled

Question

I'm using Ubuntu 18.04, and I installed the "Dash to Dock" extension. It worked, but I didn't like it, so I removed it.
But the dock is same as before, and I checked if the "Ubuntu Dock" is on, but isn't.

My dock is like this:

Ubuntu Dock is a pre-installed system extension for GNOME Shell on Ubuntu 17.10 and later releases. It cannot be reliably disabled in the default Ubuntu session using tools like GNOME Tweaks or others. Refer to this to remove the dock: How can I get rid of the dock in Ubuntu 18?

Answer 2

Update In older Ubuntu version, this answer would only have been applicable to a Gnome session (vanilla-gnome-desktop or gnome-session). In newer Ubuntu versions, the "Ubuntu Dock" can conveniently be disabled using `gnome-shell-extension-prefs.

Ubuntu Dock appears to be hardly tied into the Ubuntu session. You can only disable it by directly disabling system files. If you do not want to use Ubuntu Dock, the preferred approach is to install gnome-session. During login, select the "Gnome on xorg" session. You will then have a plain Gnome Shell without dock, without extra Gnome applications, but however retaining all theming of Ubuntu.

Then head to Gnome Tweaks and enable "Desktop icons". If you wish, you can reactivate/disable Ubuntu Dock there. The only difference will be that your clock will remain in the center of the entire screen, while in the Ubuntu session, the clock is centered in the horizontal area not occupied by the dock.

Original answer Ubuntu Dock is a fork of Dash to Dock, and uses the same configuration settings. Thus, if you installed Dash to Dock, settings remain after you remove it.

As a quirk, Ubuntu Dock may remain visible, even though it is disabled in "Gnome Tweaks". Just head to "Gnome Tweaks", "Extensions" tab, enable Ubuntu Dock briefly, then disable it again. Now, Ubuntu Dock will effectively be disabled, and the Gnome Tweak Extensions tab will be "in sync" with its actual status.

If you wish to use Ubuntu Dock extension, then turn it back on in Gnome Tweaks.

If you wish to restore the default configuration, then run the command:

dconf reset -f /org/gnome/shell/extensions/dash-to-dock/
