How To: Determine Your Desktop Environment

Today’s article will help you determine your desktop environment. Often abbreviated as “DE”, your desktop can be any number of choices – including none at all. This should be a relatively short and easy article. If you don’t know, the desktop environment is a bunch of software that provides the GUI system you use to navigate, load files, and manage your computer.

Once in a while, an article should get back to the basics. This is one of those articles. When someone poses a question and you need to know their desktop environment, you can just tell them that you need that information and link to an article like this one.

As such, it’s not exhaustive nor is it expected to be all that deep. There are a number of ways to get your desktop information. For a more universal approach, these ways will all be through the terminal. In most other situations, you can use the GUI and figure it out. For example, you might use HardInfo and get the data that way. Not everyone will have that installed, so we can just do it though the terminal.

Determine Your Desktop Environment:

This article requires an open terminal, like many other articles on this site. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

Now that you have your terminal open, you can try either ‘neofetch‘ or ‘screenfetch‘. Both of them will happily spit out the information you need. The screenfetch may be better here, as it also gives the version of your desktop environment – from what I can tell. Both are easy to install and may already be installed.

Here’s an example of the relevant output from running screenfetch in the terminal:

screenfetch displaying desktop environment information
See? It’s right there! Easy enough!

You can also do the same thing with running neofetch in your terminal. Once again, it looks something like this:

neofetch showing desktop environment
Once again, it’s nice and easy! Tada!

Now, there’s some chance you just want to determine your desktop environment and don’t need or want any additional information. You can do that. It’s not hard, it’s not hard at all. In fact, both are environment variables that you can easily get to echo as stdout.

You can also use:

Both of those will tell you the desktop environment that you’re using. See:

using echo to view the desktop environment
See? You can use either one effectively and efficiently.

As suggested by @wizardfromoz, of Linux.org fame, I completely forgot to include my beloved inxi. The inxi system information tool is increasingly installed by default, but the link will show you how to install it. It’s a great tool, providing a ton of information, that’s used frequently for support questions.

To use inxi to determine your desktop environment, you can just run:

That’s an uppercase S and it’ll look something like this:

inxi showing the desktop environment
See? It’s even included in the inxi output! inxi does it all!

And there you have it, a few different ways to determine your desktop environment from the terminal. You should probably just know this information, but newer users may not know and may need help in finding this information. 

Closure:

So, there’s another one… Yet another article, said and done. This one is pretty easy and aimed at rank beginners, but it’s not without use. It may even save some time as people might actually search before asking questions! Well, they could…

Enable x11 Forwarding With SSH (Remotely Use GUI Applications)

In the last article, I explained how to enable SSH. In today’s article, we’re going to learn how to forward GUI application windows with SSH. x11 forwarding is easy and beneficial. Once you learn how, you may decide to stop using VNC or TeamViewer.

Just to quickly clear up a misconception, x11 forwarding works just fine with Wayland. Way back in the earliest days of Wayland development, it was agreed that it should retain backwards compatibility with x11 forwarding.

What is this strange thing, this x11 forwarding?

Well, when you’re connected to another computer via SSH you can use the terminal to control the computer. That’s great, but what if you want to use a GUI application? Sure, you could set up some sort of remote desktop application, such as VNC. Or, alternatively, and often more simply, you can just forward graphic applications over SSH. It’s remarkably easy!

Perhaps a picture is in order. Check this:

gedit in action
That’s GEdit running on a different computer, but forwarded to this one. Pretty neat, huh?

That’s right. That’s GEdit running on my laptop. I’ve just forwarded the GUI application to this computer. If I write something and save it, it’d be saved on the computer that I’m connected to and not the computer that I’m using.

Amusingly, I used this exact process just recently. I had to move a complex password to my laptop and I was being lazy. So, I opened GEdit remotely and pasted in my password, transferring my new password to the other device. See? It comes in handier than you might think.

Let’s Enable x11 Forwarding:

How do you do this? Well, first you need to crack open your terminal. To do that, you just press CTRL + ALT + T on your keyboard and your default terminal emulator should open.

Now, in said terminal, you need to run the following command:

Once you have that file opened with nano, you just need to remove the appropriate pound sign (“uncomment” it out) for the right line. Look for the line that says:

And change it to:

Then save the file with nano by pressing CTRL + X, then Y, and then ENTER. (You may want to learn that, as that’s how you save files in nano.)

Next up, you’ll restart the SSH service and be done with it:

And that’s it! You can now use x11 forwarding over SSH. To do so, you just need to add the -X switch. That’s not as complicated as you might think. Nothing in this article is all that difficult.

To try to make sense of that above command, if I were to remotely connect to the MSI laptop, then my command would look just like:

You can also use the IP address, instead of the hostname, just like we discussed in the previous article about SSH. To do that, it looks like this:

x11 Forwarding in Action:

Once you’re there, just go ahead and start an application. For example, open gedit by typing just that into the terminal. You may find some applications won’t work, often due to ownership and permissions issues, but you’ll find many that work just fine. If you find one that doesn’t work, you can always check any errors thrown and go from there.

Firefox forwarded over SSH
See? Note the carefully drawn arrow that shows where it was forwarded from. Tada!

That’s an example of Firefox forwarded over SSH using x11 forwarding and you may notice the washed out look. I haven’t really dug into it, but I am reasonably confident that washed out look is because of compression. I’ve never needed to dig into that and, amazingly enough, I don’t know everything.

Conclusion:

Anyhow, there you have it. One more article in the books and one more bit of knowledge plastered across the internet. Thanks for reading!
