Short: Clear Linux Mint Notifications

This is another short article, as I continue exploring the format, and is simply about how to clear Linux Mint notifications. You can do so graphically, or you can do so with a keyboard.

I should be specific. This is for Linux Mint Cinnamon Edition.

When you get an email, when you have a notice from your email client, or have scheduled some system prompt, you might get a notification. These notifications show up in your system tray.

They look like this:

Notifications from Linux Mint.
See? I even drew an arrow for you! In this case, there are three!

These notifications show up with regularity if you have a lot of email accounts that get constant notifications. They may show up for other reasons.

If you want to use a GUI, just click the notification icon and clear it. That’d look like this image below, and it’s nice and simple:

This is probably how most of you will clear notifications from Linux Mint.

On the other hand, if you’re pretty sure there are no notifications worth reading, you can always just clear them out with the keyboard.

Clear Linux Mint Notifications With The Keyboard:

If you want to clear Linux Mint notifications with the keyboard, it’s remarkably simple. It isn’t made clear, thus you get this short-form article.

To clear those notifications you simply press the following:


Now, if you’re unsure, the ‘Super’ key is often labeled to be the ‘Windows Key’. It may say ‘WIN’ on it or it may have the Windows logo emblazoned on it. With your ‘standard’ US keyboard layout, it’s the key on the left between the CTRL and ALT keys.

This could, on Apple keyboards, also be labeled as the CMD key.

But, the ‘super key’ came first. It was an MIT (GO BEAVERS!) thing. If you don’t have anything better to do, read about the Super Key on Wikipedia. The WinKey and CMD key came later in life.

Anyhow, now you can clear Linux Mint Notifications with your keyboard!


I’m not sure if I like this short format. I normally have quite a bit to say, even if it’s mundane. There’s a lot to be said about the tools we use. At the same time, there are plenty of meaningful tips that just don’t warrant writing a full article.

So far, exactly one person has opined on the matter and they claimed to like the short articles. A few days later, they also offered the opinion that they liked the longer articles. Given their comments, I’m going to have to assume they also like the regular articles and just like my articles. I’m okay with that, but it’s not exactly information I can act on other than to just keep doing what I’ve been doing.

Increase The Volume Of Thunderbird Notifications

Today’s article is one of a personal nature, an issue that affected me personally, where I needed to increase the volume of Thunderbird notifications. It was a bit of a problem and one easily resolved – at least in my case. I think it will be trivial to overcome this for others and thought that I’d make a quick article about this.

Thunderbird is an email client. The Thunderbird email client is brought to you by the same people, that is Mozilla, that brings you the Firefox web browser. As far as graphical email clients for Linux goes, you’re probably better off using Thunderbird.

This article is specifically about the calendar. It is only applicable if you have the calendar (sometimes called Lightning) installed. Further, it is only applicable if you then also have it set to chime an audio file when a scheduled activity is due. If none of those things are true, this article is not meant for you.

I don’t allow most audio notifications, but I do rely on Thunderbird for scheduling and noting appointments. If you’ve configured Thunderbird to show notifications and to create a sound to denote those notifications, you may notice that the notification is quieter than you’d like.

I searched for a solution for the low volume of Thunderbird notifications. I had a solution in mind, but I looked for something more graceful. The goal was to find something ‘in-app’ that let me set the notification volume. Not only was I unable to find a solution in that direction, I was unable to find anyone suggesting this path to increase the volume of Thunderbird notifications.

I’ll be giving directions for Debian (and derivatives such as Ubuntu, and all official Ubuntu flavors, Linux Mint, ElementaryOS, and such) but you can adapt these directions for your needs. The tool we’ll be using is ‘Audacity’ and that’s probably going to be in everyone’s default repositories.

If you’re unfamiliar with Audacity, the application is used to edit audio. As a general rule, I don’t bother with full-fledged DAWs and prefer the simplicity that Audacity offers. So, I guess that does make it my DAW of choice.

Odds are good that you don’t have Audacity installed by default. Again, assuming you use a distro with apt, you’d simply install Audacity with the following command:

If you’re curious, the man page describes it like this:

audacity – Graphical cross-platform audio editor

That’s a fine description and Audacity is the only tool you’ll need to increase the volume of Thunderbird notifications. As near as I can tell, this will work on default sounds or the sounds you add as your notification sounds.

So then, let’s get on with it… Let’s learn how to…

Increase The Volume Of Thunderbird Notifications:

If you read the intro correctly, or at least as how I expected it to be read, then you should have already installed Audacity. You can do this with any DAW (Digital Audio Workstation) but Audacity is quick and easy, easy enough for me to use.

So, I’ll assume you have Audacity installed.

You can do this with Ocenaudio. If you want a full-blown DAW, you can do this in Reaper. You have choices, but these directions are for Audacity.

Your first step is to open your file manager. With your file manager now open, double-check in Thunderbird to see where your notification sound file is located. It’s in the Settings menu, under the Calendar settings.

Thunderbird's notifications settings.
This should be fairly easily explained. A picture is worth 1,000 words!

As you can see, I’ve chosen a custom audio file. The process is the same. You need to find the file in question or add your file. If you wanted to you could root around and find the default file, but I suggest adding your own.

Once you have found the sound file, right-click on it and open it in Audacity. You can also open Audacity and then open the file by clicking on File and then Open. Both should work on most distros.

You’ll then see a screen that looks similar to this:

We'll increase the volume with Audacity.
That’s the waveform of my ‘cymbals’ notification chime.

What you do from here is right-click on any part of the spectrum shown in the image above.

You then press CTRL + A to select the full file.

You next click on Effect and then you click on Amplify. Adjust the amplification to suit and use the preview button to judge the volume level you’d like to achieve. That screen would look something like this:

Using Audacity to control the reminder sounds from Thunderbird.
If you want to hear your Thunderbird notifications easily, this is how you do it.

This works with more than just increasing the volume of Thunderbird notifications. You can raise and lower the volumes of almost any sound file quickly and easily. Rather than mucking about with some Thunderbird extension, you can just raise the volumes yourself.


I’m not sure how many folks will be helped by this article, but I hope it’s some. This was an itch that I needed to scratch and this was how I went about doing so. I figured I’d share that with you by making it into an article. That seemed like a reasonable choice at the time.
