LMMS 1.2.1 has been made into Ubuntu 20.04 main repositories. There are also official .appimage package and flatpak package (runs in sandbox) available for most Linux desktop.

For those prefer installing LMMS 1.2.1 native .deb via apt-get, I’ve uploaded the Ubuntu 20.04 package backports into the unofficial PPA for Ubuntu 18.04 and Ubuntu 19.10.

1.) Open terminal either by pressing Ctrl+Alt+T on keyboard, or by searching for ‘terminal’ from your system application menu. When it opens, run command:

sudo add-apt-repository ppa:ubuntuhandbook1/lmms

Type user password (no asterisk feedback) for sudo prompt and hit Enter to continue adding the PPA.

2.) Then run command to refresh system package cache and install LMMS:

sudo apt update

sudo apt install lmms

Uninstall:

To remove lmms, run command:

sudo apt remove --autoremove lmms

And remove the PPA either via Software & Updates -> Other Software or by running command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/lmms

This simple tutorial shows how to send application shortcut icons to the desktop in Ubuntu 20.04 Gnome Shell.

Want to put working folders and common used applications on your desktop? It’s easy to do this in the default Gnome desktop via following steps.

Method 1: Copy & Paste .desktop files Manually

1. First open file browser and navigate to Other Locations > Computer > usr > share > applications. The shortcut files of most installed applications are there.

Open another new file browser window, and navigate to Desktop folder.

Now drag and drop desired applications’ .desktop files to the Desktop folder.

2. Then right-click on the desktop icons one by one and select ‘Allow Launching‘.

The icons should change, and will launch the applications once you click on them.

Method 2: Use an extension

There’s now a Gnome extension to make things easier! With it, user can simply search for an application and right-click on its icon, finally select “Add to Desktop” option to do the job.

To install the Extension in Ubuntu 22.04, press Ctrl+Alt+T on keyboard to open terminal. Then, run command to install extension manager:

sudo apt install gnome-shell-extension-manager

Next, press Windows/Super key on keyboard and then search for and open the extension manager:

Finally, search for and install “Add to Desktop” extension under ‘Browser’ tab and enjoy!

Ubuntu 20.04 user may install the extension by visiting this gnome web page.

Ubuntu 20.04 Gnome 3.36 brings a little change on the top-right corner system tray menu. Log Out, Switch User, Suspend, and Power Off are now sub-menu options of a new ‘Power Off / Log Out‘ button.

For those don’t prefer the new sub-menu, a Gnome Shell Extension is available to bring out the submenu of ‘Power Off / Log Out‘ and rearrange the order of system menu.

Install the Extension in Ubuntu 20.04

1. Open Firefox or Google Chrome and go to https://extensions.gnome.org.

3. After that, you’re able to install the Gnome Shell extension by going to https://extensions.gnome.org/extension/2917/bring-out-submenu-of-power-offlogout-button/.

If everything’s OK, system tray menu should change. And you can manage the extension either via Extensions utility or Gnome Tweaks.

Install the Gnome Extension in Ubuntu 22.04

Ubuntu 22.04 defaults to Firefox as Snap which does not support installing Gnome Extensions. Besides using another web browser, here’s another way to install the extension to bring out “Power Off / Log Out” sub menu.

Miss Ubuntu 18.04 style dynamic top panel transparency? Here’s how to get this function in Ubuntu 20.04 gnome shell.

Although top panel transparency was removed since Gnome 3.32, you can get the feature back via ‘Dynamic Panel Transparency‘ gnome shell extension.

The extension fades your top panel to nothingness when there are no maximized windows present. With extension settings, you can also:

  • change transition speed.
  • set custom panel opacity.
  • change foreground text color.
  • per-app basis settings.

1. Open Firefox or Google Chrome and go to https://extensions.gnome.org:

Click the link text “click here to install browser extension” and follow the pop-ups to install the browser extension:

2. Then open terminal via Ctrl+Alt+T and run command:

sudo apt install chrome-gnome-shell

3. Go to dynamic-panel-transparency/ page, and click the toggle to install the extension.

4. The extension is not updated for Gnome 3.36 at the moment. If you see an error, run command in terminal:

gedit ~/.local/share/gnome-shell/extensions/dynamic-panel-transparency@rockon999.github.io/intellifade.js

And in pop-up text editor, find out and change following lines:

let anchor_y = -Main.layoutManager.panelBox.get_anchor_point()[1];
let pivot_y = -Main.layoutManager.panelBox.get_pivot_point()[1];

// Adjust for bottom panel.
if (anchor_y > 0) {
this.panel_bounds.y = anchor_y;
this.panel_bounds.is_top = false;
} else if (pivot_y > 0) {
this.panel_bounds.y = pivot_y;
this.panel_bounds.is_top = false;
}

into:

let pivot_y = -Main.layoutManager.panelBox.get_pivot_point()[1];

// Adjust for bottom panel.
if (pivot_y > 0) {
this.panel_bounds.y = pivot_y;
this.panel_bounds.is_top = false;
}

Save the file. And restart Gnome Shell by pressing Alt+F2 on keyboard, typing “r” (without quotes) and hit Enter.

Finally, launch “Extensions” utility, turn on ‘Dynamic Panel Transparency’ extension and change its settings and enjoy!

In addition, you may also adjust the left dock panel opacity by running command (change 0.2 in the code):
