How To: Quickly Restart The Cinnamon Desktop Environment

Today’s article is going to be a pretty quick and easy article, where you learn how to quickly restart the Cinnamon desktop environment. It shouldn’t be a very long article, and I’d say it’s easy enough for a beginner to process. So, if you’re interested in restarting the Cinnamon DE, read on!

Obviously, this will only apply to those folks who are using the Cinnamon desktop environment. Well, no… I do believe it also works in the GNOME desktop environment. As I understand that it’s a holdover from GNOME, which is what Cinnamon is based on. Alas, I don’t have anything running GNOME right here in front of me, so I’m not going to test that.

On the off-chance that you don’t know what desktop environment you’re using, that’s easy enough to learn. You can just read this article:

How To: Determine Your Desktop Environment

If you want to skip reading that, just open the terminal and run the following command:

echo $DESKTOP_SESSION

1	echo $DESKTOP_SESSION

The output of that command will tell you what desktop environment you’re using. If the result is ‘cinnamon’, then this article applies to you!

Anyhow, if you leave your computer on for a long time, you might find that Cinnamon is eating up a bunch of RAM and CPU. You can clear that out by logging out or rebooting, but there’s a much easier way to restart the Cinnamon desktop environment. This article will show you how.

Restart The Cinnamon Desktop Environment:

This time around, you don’t even need to open a terminal!

With your keyboard, press ALT + F2 and you should have a new window open up on your screen. It looks like this:

Now, all you need to do to restart the Cinnamon desktop environment is press the letter R and then press the ENTER key.

That alone, that little shortcut, will restart your Cinnamon desktop environment, meaning it may free up some RAM and lower the amount of CPU that the desktop environment is using.

Bonus:

You can actually run other commands from there. I don’t know all of them, or at least I don’t know if I know all of them. I’ve been unable to find an exhaustive list and I only know of a few shortcuts you can use in this run screen.

There’s a shortcut, like ‘rt’ that will reload your theme (useful for theme creators). It just reloads the theme, and doesn’t actually restart Cinnamon, though it may kinda look similar.

This won’t apply to too many of my users, as my readers are generally beginners, but you can also enter ‘lg’ into the shortcut window.

If you were using GNOME instead of Cinnamon, it’ll open up “looking glass”, the GNOME debugger.

If you’re using Cinnamon, it opens up Melange – the Cinnamon debugger. Debuggers can be useful if you need it and know what you’re doing with it.

The goodness doesn’t stop there!

If you want, you can put ‘firefox’, ‘gedit’, ‘leafpad’ or other applications in there. So long as those applications exist in /usr/bin, they should load just fine from this run screen. You can use this shortcut to open pretty much any application that has been installed via the normal means.

If you want to load something that’s not installed from this screen, you can do that too. You just need to enter the path to the application you want to open. Something like, ~/Downloads/LibreWolf.AppImage will work, according to my testing.

Closure:

There you have it! You’ve learned how to use a hidden run menu to restart the Cinnamon desktop environment. On top of that, you’ve learned that it can be useful for all sorts of other tasks. It’s a pretty handy shortcut, one you can open without taking your hands off the keyboard to use a mouse. That right there is quite a bonus in and of itself!

How To: Cancel Your LastPass Account

This is just a PSA type of article, about how to cancel your LastPass account. Below are the reasons why you might want to cancel your LastPass account and how you can go about actually canceling that account.

Below is a copy of a recent email from LastPass:

Dear LastPass Customer, 
We recently notified you that an unauthorized party was able to gain access to a third-party cloud-based storage service which is used by LastPass to store backups. Earlier today, we posted an update to our blog with important information about our ongoing investigation. This update includes details regarding our findings to date, recommended actions for our customers, as well as the actions we are currently taking.
We thank you for your patience and continued support of LastPass.
The Team at LastPass

Click the link in the quoted text for more information.

I can no longer trust LastPass with my passwords and wanted to quit their services, closing my account. The only link I could easily find was at the bottom of their email – and that would simply unsubscribe you from their email list.

With the help of @Condobloke on Linux.org, I was eventually able to find how to close my LastPass account (so I’m told by LastPass). When closing my account, they asked for a reason. The reason I gave was:

I no longer have faith in your security

For the record, I had never used LastPass for anything. I had just signed up for an account. I never actually used the extension or their services.

Cancel Your LastPass Account:

The first link you’ll see is in their email, and all that option does is remove you from their mailing list. You’re ONLY unsubscribing to their email list, not actually removing your account.

That’s this link:

http://417-klk-478.mktoweb.com/lp/logmeintransact/UnsubscribePage.html?mkt_unsubscribe=1

Link left plain on purpose. That link will ONLY remove you from their mailing list. It will not delete your account. So, I recommend deleting your account before removing yourself from the mailing list.

To delete your account, you need a link provided by @Condobloke:

https://lastpass.com/delete_account.php

Again, the link is left plain on purpose. That link will only get you started.

When you have logged in and clicked the button to remove your account, your account is still not deleted. You need to check your email and they send you an additional link. You can use that link to remove your account, remembering to confirm it when they ask time and time again.

When they ask you for a reason as to why you’re removing your account, you might want to tell them that it’s because you can no longer trust their security. They had the chance to be secure and failed. They might be making the ‘right steps’ now, but those steps should have been made before now.

What You Can Do:

If you’re going to use a password manager, you are better off getting one where you control the data. That means you want an ‘offline password manager’ that’s free and (hopefully) open source (so it can be audited, if need be).

I do not have enough experience with offline password managers to make a recommendation. I also am not going to be the one to suggest a specific product only to find out I sent you barking up the wrong tree. So, my suggestion is that you use your favorite search engine and look up ‘offline password manager’. Then, pick what you think works best for you.

I’ve done some looking and this article looks solid. I make no recommendations based on that link, it just looks pretty thorough to me. The article may contain errors and I’m not responsible for that, as I lack the time to dig deeper into this due to a rather impressive winter storm.

Good luck and do due diligence before deciding on a specific offline password manager platform. Read reviews, check security history, make sure it’s easy enough for you to use, and make sure it works with the software you intend it to work with.

Closure:

Well, I don’t use the ‘News’ category often, but this seemed like an important article to get out there. It’s time sensitive so it’s not going to be scheduled for publication, it’ll be published as soon as I’m done proofreading it.

Stay safe out there. Remember, “Practice safe hex!”

EDIT: Fixed a typo.

Find A Command’s Binary

Today’s article should actually be fairly short and simple, as we learn how to find a command’s binary. For those of you who are new, I’ll do what I can to make this more clear. At the end of the day, all should become clear and it really shouldn’t take all that long.

So, when you run a command in the terminal, you’re calling the binary file that is that program. This is also true when you’re starting a command in a GUI environment. You’re loading a binary file. Well, no… You could be loading some sort of script – but most of the time you’re going to be loading a binary.

Well, what we’re going to do is show you where to find these binaries by using the ‘which’ command in the terminal.

HINT: They’re generally tucked away in /usr/bin/!

The command we’ll be using is the ‘which’ command. It’s a very simple command to use when you just want to find a command’s binary. If you run the ‘man which‘ command (not the sandwich made from burger) you’ll find it is described accurately, and as thus:

which – locate a command

And, that’s really all the command we need for this exercise. It’s dirt simple, but still worthy of its own article. Ready?

How To: Find A Command’s Binary:

Yup. You guessed it. We’ll be using the terminal for this article. We do that a lot at this site. So, open up your default terminal emulator. 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.

With your terminal now open, try any one of the following:

which dir

which dir

Or:

which firefox

1	which firefox

Perhaps:

which teamviewer

1	which teamviewer

That’s right, the entire usage is just:

which <application>

1	which <application>

It even works for proprietary things, like:

which google-chrome

1	which google-chrome

If you want to be more curious, you can even find the binary for the very ‘which’ we’re using in this article:

which which

1	which which

See? This is so dirt simple that an absolute n00b can be up and using the ‘which’ command pretty much instantly! Using the terminal doesn’t have to be complicated. You can get comfortable using the terminal in just a few days and you’ll be better for it.

Closure:

So, yeah, that’s all the article you really need when your goal is to find a command’s binary file. It’s not even a wee bit difficult – and is a great way to explore the terminal when you’re new to it. Have fun!

How To: Install XnView MP On Ubuntu

Today’s article is going to do exactly what it says in the headline, it’s going to show you how to install XnView MP on Ubuntu. It won’t be a very long article, perhaps a bit longer than some, nor will it be all that difficult. XnView is a great photo viewing and manipulation application that I invite you to try out. I’ll be counting this as a review. That defines it best.

First, let me be clear… XnView is a closed-source application. It is proprietary and you never own the software. That doesn’t make it bad, it’s great software, it just means that some people may choose to ignore this article in favor of truly open software. That’s okay, they have that choice. Yay! Freedom!

So, what is XnView? It’s an image viewing/manipulation tool. It even allows you to do some batch processing on images, while offering some great ways to visualize your image collections. I was a fan back when I used Windows. When they started releasing versions for Linux I was pretty stoked.

In fact, it used to be XnView and now it’s XnView MP with the ‘MP’ standing for ‘multi-platform’. And, well, that’s true. It is mult-platform. And, well, that’s a great thing. I love this program!

I have previously mentioned XnView MP in these articles:

Let’s Reduce The Size Of .png Files
How To: Sanitize Exif Data From Your Digital Images For Privacy Sake

And, while this article is aimed at Ubuntu, it will work for other distros with just a few changes. Feel free to check XnView.com to see if they have a download for you.

More About XnView MP:

See, the greatest thing about XnView MP is exactly how many image files types it can deal with. It works for *all of them*. You’ll have to work REALLY hard to find an image format that doesn’t work properly in XnView.

Lemme find you a link…

Here, XnView handles more than 500 image formats. I wasn’t kidding. You’ll work REALLY hard to find an image format that’s unsupported by XnView MP!

Not only that, you can convert between image formats. You can not only do so, you can batch process them. If you visit the link, everything with the ‘write’ box checked can be converted to. It’s an easy to operate application, as well.

You can also do things like watermark an image – and, again, do so by batch processing your image collection. There are other tools from the same company, including XnConvert which is a more specialized tool. Examine those in your free time, if you’d like.

Anyhow, XnView MP has the usual tools. You can resize and crop. You can edit red eye out of the image. You can adjust contrast and light. Then, there are a variety of effects and filters you can apply.

Finally, or not, you can view your photo collection in a variety of ways. You have everything from filmstrip view to slideshow options. There’s a bunch of different choices and things like EXIF data are supported. You really can’t go wrong with XnView MP.

How To Install XnView MP:

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.

Once you’re there, let’s change to the Downloads directory:

cd Downloads

1	cd Downloads

Next, you’re gonna download XnView MP:

wget https://download.xnview.com/XnView MP-linux-x64.deb

1	wget https://download.xnview.com/XnView MP-linux-x64.deb

Finally, you’ll want to install XnView MP:

sudo apt install ./XnView MP-linux-x64.deb

1	sudo apt install ./XnView MP-linux-x64.deb

Now, XnView MP updates frequently, so you’ll want to remember this page and these steps. When XnView MP updates, simply run the above commands all over again and you can update XnView MP on Ubuntu. It’s amazing what you can do in the terminal. You can do all the things in the terminal!

Bonus:

By pure happenstance, I happened to check this on a Linux Mint box. It’s an older version of XnView, but you can actually find a version of XnView in the default repositories. It probably(?) won’t update with nearly the same frequency as your manual updates, but Mint users can install XnView with:

sudo apt install xnview

1	sudo apt install xnview

Follow the prompts and you can install what I suppose would be a supported version of XnView. I can’t think of any good reason to use an older version, but I wanted to mention that the option is there. Then again, it might just be the same and update with the same frequency. I confess that I’ve never tried it.

Notably, there’s no such option on Lubuntu (Ubuntu) 22.04. So, I guess it’s a Mint thing. Even with Mint, I’d expect that you’ll be just fine by installing XnView MP with the method above. The above method will, of course, work on any system that’s using a package manager that works with .deb files. Easy peasy…

Closure:

And there you have it. You have a new article! This time around, you’ll have learned how to install XnView MP on Ubuntu. It’s not terribly difficult and it’s a great application.

Sure, it’s proprietary – but that doesn’t necessarily mean it’s bad. If you’re philosophically opposed to closed source software, this article isn’t really meant for you. Again, this is really more of a review – a way to make more Linux users aware that XnView exists and is available for Linux.

How To: Extract Files From An .iso

In today’s article, we’re going to learn how to extract files from an .iso. This is a good tool to add to your toolbox. You never know when you may need it. This really shouldn’t be a very long article, and even a new user should be able to follow along. Read on!

First, an .iso is really an optical disk image – even though some of the current .iso examples far exceed what you can write on a CD or even a DVD. You still use an .iso when you’re writing a Linux live/boot USB. It’s still an optical image, you’re just not writing it to optical media. It’s a standard.

Commonly, you’ll find that Linux distros come in .iso format. You’ll also find some backup software that creates an .iso image. Traditionally, you don’t extract an .iso, you write it as a single image to your media, be it USB, CD, or DVD. But, sometimes you might want to extract files from the image file, and it’s not terribly hard to do so.

Extract Files From An .iso:

Just like so many previous articles, we’re going to do this in the terminal. So, crack open your terminal and we’ll get started. If you don’t know how to open your default terminal emulator, just press CTRL + ALT + T and your default terminal should open.

With your terminal now open, the first thing you have to do is make the correct directory in your /mnt (mount) directory. It looks like:

sudo mkdir /mnt/iso

1	sudo mkdir /mnt/iso

Next, you want to mount the .iso, which is done like this:

sudo mount -o loop /path/to/file.iso /mnt/iso

1	sudo mount -o loop /path/to/file.iso /mnt/iso

Now, at this point, you can do one of two things. If you want to remain in the terminal, you just ‘cd /mnt/iso‘ and start with ‘ls -la‘ to navigate and find the file(s) you want to extract from .iso. Pretty easy, really!

Alternatively, at this time, your system will now see the .iso as being a mounted image file. You can open your default file explorer (Nemo, PCManFM-Qt, Thunar, Dolphin, and the list goes on and on and on…) where you should see the .iso mounted, especially if you navigate to /mnt/iso. You can then navigate to that mounted image graphically, treating it like its own file system, and extract files as you see fit.

The choice is up to you. You can use a GUI file manager or just use the terminal. Both will be equally effective and allow you to extract files from an .iso. See? Not all that hard at all. Find an .iso on your system and test it.

Closure:

And there you have it, you have yet another article! This time, we’ve gone over how to extract files from an .iso. This isn’t something you’re likely to need often, but it’ll be handy when you do need it. It’s just one of those tools you stuff into the back of your mind for when you do need it – or at least enough to be able to get a reminder by way of a search engine.
