HowTo Scanners on Linux(Raspberry Pi) – Project SANE

It turns out, even old scanners has a function in the modern era, thanks to our brothers and sisters at the SANE project.

For printers, you have CUPS and for scanners you have SANE

They pretty much saves the day if you don’t want to have a dedicated Windows PC just for scanning or printing every once in a while. As the world shifts to the full digital age, it’s less and less common to perform these tasks.

But as we all know; when you need the old hardware to work, you need it badly. Printers are not famous for being very trustworthy or stable. Because after all, the manufacturers make money on the ink and not on good hardware. It’s a perfect study-case for a tiny Raspberry Pi, as these tasks don’t require much horsepower.


Raspberry Pi File Manager keeps crashing

Recently I had a case where Raspbian’s default file manager(pcmanfm) kept on crashing.

The user would click on the icon, the application would open and then immediately close or crash. If the application was executed from terminal, the same results were met.

I had a look at the logs and noticed that pcmanfm kept on throwing out a “Segmentation fault

A quick fix for this issue is to reinstall the pcmanfm:

sudo apt-get install --reinstall pcmanfm


Keyboard Shortcuts Keys

What is a Keyboard Shortcut?

In computing, a keyboard shortcut is a set of one or more keys that invoke a command in software or an operating system.

They are typically an alternate means for invoking commands that would otherwise be accessible only through a menu, a mouse, or an aspect of the user interface. These shortcuts can expedite common operations by reducing input sequences to a few keystrokes.

These shortcuts can provide an easier and quicker method of using computer programs. These commands are commonly accessed by using the [Alt] key (on PC computers), [command key] (on Apple computers), [Ctrl], and [Shift] in conjunction with a single letter.

These shortcuts are for the following programs and applications.

  • Word
  • Windows
  • Internet Explorer
  • File Explorer
  • Windows System Commands
  • Firefox
  • Excel
  • Mac
  • Finder
  • Chrome

Autorun apps Raspberry Pi on Raspbian GUI / Terminal

Raspberry Pi 3Sometimes you want stuff to run at startup, be it an application or a forced setting. This is fairly easy to achieve in Rasbpian, here’s how:

You can use the Raspbian preferences via the GUI to cause the pi user to be auto logged in at boot up and the GUI to automatically run. However, if you need to run with root privileges due to needing IO pin control (PLEASE NOTE: It is not advised to run as root) then set the Raspbian preferences to boot to the command line. Now open this file by editing it(you can use your favourite editor, for this example we use nano):

sudo nano /etc/rc.local

Before the “exit 0” line in it add the following line:

#Auto run the GUI as root
sudo startx

Save it by pressing Ctrl+X, ” Y“, ENTER

Reboot your RPi and it should automatically run the GUI as the root user.
