How do I install RaspEX in Linux?

 

You can of course also install RaspEX in any Linux system using the dd command. Just open up at terminal and run the following command (as root):
dd if=raspex-ubuntu-18.10-lxde-4400mb-181015.img of=/dev/sdbs=1M
Note: 
Change /dev/sdX to for example /dev/sdc, /dev/sde or…
(Check it carefully before you run the above command so you won’t lose important data).

Different Micro SD Cards
For best performance you should use SD Cards of good quality. I can recommend Samsung MicroSD Pro Plus 32GB Class 10. Write speed up to 95 MB/s. Also Samsung MicroSD EVO 16GB Class 10. Write speed up to 48 MB/s. Price 47 $ respectively 10 $ (in Sweden).

How do I use RaspEX?
When you start up your Raspberry Mini computer with RaspEX you will (after a few seconds) end up in X and LXDE as the ordinary user raspex. The password for raspex is raspex. When logged in as raspex you can use Sudo to become root. Example: sudo su and sudo pcmanfm. The password for root (superuser) is root. You can log out from LXDE and log in again as root (if you want). This is how it looks at SLiM‘s login page.

You can log in as root with password root. You can of course also create a new ordinary user if you want. Command: /usr/sbin/adduser MyNewUser. If you don’t want to be automatically logged in as raspex you shall edit /etc/slim.conf.

When logged in as the ordinary user raspex your Desktop will look like this.

First two things to do after installation to your SD card
1. Run the command sudo sh /root/resize_rootfs.sh
After that all the space on the SD card will be used.
2. Run the command sudo dphys-swapfile setup
SWAP file of 2 GB will be created. Then run the command dphys-swapfile swaponVery useful if you want to run many programs at the same time.

Error no_pubkey when trying to upgrade the system
When you run the command sudo apt-get update it can happen that you can’t update the sources due to missing pub_keys. The solution is to run the following commands.
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt update

Solve Apt-get : NO_PUBKEY / GPG Error in Debian

Simply type the following commands, taking care to replace the number below with that of the key that was displayed in the error message

{—————————————————————————}

After that you can run apt-get update with success even though you still will get the same “no_pubkey” errors. Don’t worry. This error won’t prevent you from upgrading the system regularly with the command sudo apt upgrade.

Wireless connections
The new Raspberry Pi 3 and 3 Model B+ computer has “built in” 802.11n Wireless LAN.Using Raspberry Pi 2 you have to have a Wireless USB Adapter. The only one which works for Raspberry Pi 2 is Edimax EW-7811Un (as far as I know).

Expand the filesystem on the SD card
If you install many new big programs and/or download large files (for example videos) you may run out of space on the SD card. That is best fixed by running the following command: sudo sh /root/resize_rootfs.sh
NOTE: That’s all you have to do. Just wait for the script to fix everything. If you use a SD card of 64 GB all the space on it will be used afterwards.

How to use Raspotify
Raspotify (Raspotify is a Spotify Connect client for Raspbian on the Raspberry Pi 
that just works) is pre-installed and immediately ready for connections. You’ll need a
Spotify Premium account in order to connect to for example your mobile phone running Spotify.

About SSH, PuTTY, Samba, RealVNC and VNC Viewer
SSHPuTTy (Telnet/SSH client for X), Samba and RealVNC are pre-installed in RaspEX Build 181015. You need to install PuTTy and and VNC Viewer in your Windows system if you want to connect to RaspEX/Raspberry Pi 3/2 from Windows the way the below slideshow shows. (Please read the developers information about how to configure PuTTy and VNC Viewer).

Watch this slideshow re. connections between RaspEX and Windows.

Bluetooth connections – working in Build 181022/181015
It seems difficult (maybe impossible) to use the “built in” Bluetooth adapter running RaspEX on Raspberry Pi 3 Model B. Using a Bluetooth dongle for example Asus USB-BT400 dongle on Raspberry Pi 3 Model B and Raspberry Pi 2 you should have no trouble using Bluetooth in RaspEX. Watch these two screenshots when Blueman (Graphical Bluetooth Manager) is running. Using the new Raspberry Pi 3 Model B+ it should be easier to use Bluetooth.

THE IMPORTANCE of RaspEX LXDE now being based on Ubuntu 18.10 (UNSTABLE/DEVELOPMENT)

I don’t think it is too important since RaspEX doesn’t use complicated Desktop Environments like KDE, Gnome or Unity. Programs won’t crash or anything like that. And I haven’t discovered any bugs to report. Besides Ubuntu 18.10 will be released 181018 in a stable version. The FinalFreeze was already 181011 though.
