AOC USB Displaylink Raspberry Pi
There’s good news and bad news:
Bad News:
You expected to struggle with this. You expected that this will be as tricky as it used to be. Rotten luck, chum.
Good news:
Create a file called called:

Autorun apps Raspberry Pi on Raspbian GUI / Terminal
Sometimes 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.

Turn off Screensaver – Raspbian / Raspberry Pi
Does that annoying screensaver keep popping up? Is the screen going blank another thorn in your side? No problem:
First you have to edit the autostart file
For the standard Pi user:
sudo nano /home/pi/.config/lxsession/LXDE-pi/autostart
For the root Pi user (if running the GUI with “sudo startx” for instance when running apps that access the IO pins):
sudo nano /root/.config/lxsession/LXDE-pi/autostart
Unfortunately in recent updates, the above has changed in that really annoying way that happens all to often with Linux versions, but seems to be the current file that needs to be edited. It used to be these but they no longer seem to work with the latest version of Raspbian:
sudo nano /etc/xdg/lxsession/LXDE/autostart
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
Updates – Site, Sound, Shikaka
Wow man, it has been ages since I contributed in any way towards my blog. I suppose it cannot be called a blog as a blog gets updated. This, I’m afraid, has not been the case with my little home on the web.
I’ve updated the back end of WordPress to the latest version and while I was at it, I realized that the theme I was using would have looked good back in my younger days or, worse yet, the days of Geocities. In light of that, an update and change was needed. I scratched deep & hard, not to mention thought about it for quite some time(about 3 minutes) and decided on dropping all fancy crap and instead go with a smooth, responsive and open look.
I might, at some point, decide to add more images and perhaps a real logo but until that day decides to roll in, this will be the future. If I’m really honest with myself I can admit that the old logo looked horrible. I’m not even sure if you can call it a “logo” by today’s standards. Heh, what a flop.
Work has been insanely busy lately. But busy in the best sense of the word: Toys. I’ve been getting new toys every week and have been worse than a kid at Xmas. I have been actively involved in the Raspberry Pi scene and with that came some really interesting projects.
But, more of that in a while.
Create Custom Splash screen for Raspberry Pi
This solution works but there are a few seconds of text shown before the boot image appears.
Install fbi
sudo apt-get install fbi
Copy the splashscreen image to be used
Copy your custom splash image into: /etc/ and name it “splash.png“.
Presumably the resolution to use is 1920x1080px.
Create A Script
sudo nano
Paste the following into the text editor:
#! /bin/sh
### BEGIN INIT INFO
# Provides: asplashscreen
# Required-Start:
# Required-Stop:
# Should-Start:
# Default-Start: S
# Default-Stop:
# Short-Description: Show custom splashscreen
# Description: Show custom splashscreen
### END INIT INFO
do_start () {
/usr/bin/fbi -T 1 -noverbose -a /etc/splash.png
exit 0
}
