Open Source Musings


When I test drove Zorin OS Core in 2022, something that mildly vexed me was that I couldn't change the background of the desktop from an image to a solid colour.

But, as always with Linux, there's a workaround. Like the one I discovered in this post in the Zorin OS forum. Here's what to do:

Crack open a terminal window, copy and paste the command below, and press Enter:

gsettings set org.gnome.desktop.background picture-uri ""

That removes the wallpaper. To change the desktop background to a more pleasing colour, find a colour picker app (whether online or on the desktop), and get the hex code for the colour you prefer — for example, #3a79bc.

Then, copy and paste this command into a terminal window:

gsettings set org.gnome.desktop.background primary-color 'your-hex-code'

Replace your-hex-code with the code from the colour picker app. Here's an example:

gsettings set org.gnome.desktop.background primary-color '#3a79bc'

Correct spelling doesn’t seem to be very important to many people these days. There are, however, those of us for whom it is. Yes, I am one of those people.

While I’m not a spelling cop, misspelled words stick out when I encounter them. They hurt my eyes. They hurt my brain.

Any good text editor and, of course, any word processor packs a spelling checker. If you're working in plain text, you can go another route to check the spelling of your document: at the command line. How? With the help of a nifty utility called GNU Aspell (which I’ll be calling Aspell from here on in).

Aspell is fast, easy to use (yes, even for a command line tool!), and flexible. Let’s take a look at how to use it.

There are a number of utilities that enable you to view text files when you're at the command line. One of those utilities is more.

more is similar to another tool called less. The main difference between them is that more only allows you to move forward in a file.

While that may seem limiting, it has some features that are worth knowing about. Let's take a quick look at some of what more can do and how to use it.
