There are two different versions of the "MARK2" release:

Version	Description	Includes	Link	Size	Checksums (sha256)

Notes:

• It is trivial to change from LXDE to Xfce (or any other desktop environment), adding a new user interface atop the minimal install is more advanced as manual setup of USB-Networking or wifi is needed to do so.
• All images have automount ( for USB-Sticks, external Hard-Drives etc. ) and ALSA sound support

Verify that your download is OK

• After you download the version you picked, verify its checksum to make sure the integrity of the downloaded file matches (in being an exact copy the one on the server)

1. open up a terminal
2. "sha256sum ~/downloads/pandian/<image.7Z>" (input where you have the file and the one you chose to download)
3. make sure it matches the given md5sum, if not, try to download another copy. This step isnt mandatory, but its there to make sure everything is fine before we proceed.

Unzip the downloaded image

• Unzipping 7z archives

1. Open up a terminal (or do it your way)
2. Enter"7zr e <image.7z>"
3. You now have an unzipped image

(Optional) Preparation, find out where to install

This step helps you find out where the SD card is mounted.

If you have an build in SD-Card-Reader this is normally /dev/mmcblk0p1 ( in Debian ) If you have an USB-Card-Reader this is something like /dev/sdc ( in Debian )

• Open an Terminal and input "lsblk"
• You will get a list with the actual Block-Devices
• The SD-Card should be of type 'disk'

You can also try gparted to see which devices you have and identify the SD-card from there

Install the image to the SD-Card

1. Here it will be /dev/sdx

(note that the x after the sd is the drive letter, it could be sdb sdc or sdd and so on, lets say its sdc. Which means c is the drive letter for the SD-card and that sd- a and -b are in use for other things.

When writing to the device, make sure not to include the following number, which is the partition sdc1 sdc2 etc. since we are using the base card here)

This means considerations for partitions and filesystem are taken care of, so no need to worry about that. Do not pick the wrong drive however, since dd will happily write the image to somewhere it isn't supposed to if you just give it root privileges and hit enter.)

1. Copy image to SD-Card with "dd if=<image.img> of=/dev/sdx"

You now have Pandian installed on your SD card and its ready to go. :) However after copying the image to the SD-Card resizing the partitionspartitions is needed to fully utilize the space, since by default the install is limited to 2GB. (If your card is bigger Pandian is still limited to those 2GB)

(Optional) Resize SD-Card

• This can be done with gparted on linux|gnu
• start gparted

The actual partitions of the SD-CARD. Please select the correct device at the top right corner.

Rightclick to the second partition and select Resize/Move

You see the actual Size of this partition

Move the slider to the right, or set "Free space following" to 0

After you press the "Resize/Move" button, you get the preview of the new partition structure

When you press "Apply all operations", youve got a warning that you can loss your Data.
THIS IS THE LAST CHANGE TO CHECK IF YOU SELECTED THE CORRECT DEVICE.
Press Apply if everything is correct.

• After everything is fine, you have a fresh install of Pandian on you SD-Card

Startup wizard

• Upon first boot of Pandian, there is a first-start-wizard which guides you through some basic settings.

These are: Locale, timezone, time and date, password for admin and user setup and finally calibration of the touchscreen. The script is located in /usr/sbin/pdSetup should you need to run it again.

Navigation

• Inside a dialog you can navigate with the cross/dpad
• Hit space to select a checkbox
• Moving between <Ok> and <Cancel> can be down with the use of TAB ( Tap Fn then tap Space )
• Acknowledge with Enter

• All done, enjoy :)

Network connection instructions:

normal

• Use network-manager

minimal

• Use ceni network manager

(Optional) Update of Pandian system

• After you setup your Pandora, it is useful to update your system. It is a rolling release, which means since the image was made, the system is forever updated with new packages.
• open a terminal
• get root ( command is: "su" )
• enter "apt-get update" to download package information from the repositories
• enter "apt-get upgrade" to update all packages that are out of date

(pandian packages are also updated this way :)

• Note: to update only the pandian-packages enter "apt-get upgrade pandian*"

Upgrade from "minimal" to "normal"

It is possible to upgrade from the "minimal"-image to the "normal"-image. This can simlpy be done by installing the pandian-lxde debian package

• get an connection to the internet(tm) with ceni
• open an terminal
• get root ( with command: "su" )
• update package list with: "apt-get update"
• install pandian-lxde with "apt-get install pandian-lxde"
• after everything is finished login with the user you setup before
• open an terminal
• get root ( with command: "su" )
• load keymap with "xmodmap /etc/skel/.pndXmodmap"
• the easiest way is to activate the first-start-wizard with "insserv firstuse"
• reboot and go through the wizard

Additional Users/Groups

There are additional Users/Groups added to the standard debian-users

Groups

• admin

This superuser privilege is used by sudo for admin task like shutdown etc.

• mpd

This user/group has access to mpd-related files ( socket, pid-files )

Power-Modes

LID-Close

• If the lid is closed only the screen will be disabled

Low-Power-Mode / Shutdown

Switch

• Switch to left: Pandora will go to low power mode ( reduce CPU, Disable LID, Pause processes )
• Switch to right: Shutdown the pandora

pdcmd

• This script handles all system-related stuff, like lid, low-power, usb or wifi.
• This should run as root

Usage:

Command	What's done
/usr/sbin/pdcmd LCDBright +	Increase the light of the lid
/usr/sbin/pdcmd LCDBright -	Decrease the light of the lid
/usr/sbin/pdcmd LCDBright 10	Set the Brightness of the lid to 10
/usr/sbin/pdcmd LCDTrigger	Trigger the lid ( WARNING: THIS DISABLES THE LID ! )
/usr/sbin/pdcmd USBNetTrigger	Enable the USB-Networking (module g_ether). If usbnetworking is on, it will disable it
/usr/sbin/pdcmd USBHostTrigger	Enable the USB-Host (module ehci-hcd). If USB-Host is on, it will disable it
/usr/sbin/pdcmd WLANTrigger	Enable Wifi. If Wifi is enabled it will be disabled

Several tweaks

Making the Pandora Button work like the Windows key

Many users complained, their Pandora Button has no function in Pandian. This can be changed by mapping the button as "mod4".

• Make sure, the file .pndXmodmap is read in on startup. Open the file .xsessionrc in your home directory and, if not existent, add following to the last line:

 xmodmap /home/yourUsername/.pndXmodmap

• There must be the absolute path (no "~/").
• Insert in the last line of the .pndXmodmap from your home directory:

 add mod4 = XF86MenuKB

Openbox

Pandian comes with an unconfigured Openbox as a possible session. Here are some config templates.

Use the Pandora key to start the menu

• If not existent,

 cp /etc/xdg/openbox/rc.xml /home/yourUserName/.config/openbox/

• Open the rc.xml with a text editor and search for the section <keyboard>.
• Insert the new keybind:

 <keybind key="XF86MenuKB">
     <action name="ShowMenu">
       <menu>root-menu</menu>
     </action>
 </keybind>

Intuitive Openbox configuration template

Prerequisites:

• mapped 'Pandora key' as 'Windows key'(see above)
• optional: use tint2 as panel

Features:

• Changing window by [Ctrl] + [up]/[down]
• Changing workspace by [Ctrl] + [left]/[right]
• Closing window by [Ctrl] + [Q]
• Screenshot (window): [Ctrl] + [Shift] + [Alt] + [F11]
• Screenshot (whole desktop): [Ctrl] + [Shift] + [Alt] + [F12]
• and some more

Download: rc.xml

Intuitive Openbox menu template

Features:

• Most important programms in root menu
• menu entries for WLAN, USB host and low power mode

Download: menu.xml

Network Fix for pandian-minimal

If you download the pandian-mark2-minimal-hf_2014-01-02 image there is a lack of tools for setup wifi networking.
Note: For the actual download of pandian-minimal, wifi-network-tools are included

• Therefore download the fix and place it on the SD-Card where pandian is installed. (you need to have local superuser privileges on your own system as the SD contents aren't owned by your user)
• Boot pandian-minimal
• login with user: "root"
• switch to root-directory: "cd /"
• untar the network-fix: "tar -xf /path-where-file-is-located/pandian-mark2-minimal-networking_2014-01-03.tar.gz"
• setup the fix with command "pdMinimalNetwork"

• after the script is finished, run "ceni" and setup your wifi-connection

Resize

Default installation is limited to 2GB, if you want to expand it, you can, provided you have installed it on a bigger SD-card and want to make use of the space.

• Size will be changed with parted
• parted /dev/sdx
• show size with "print free"

1. (parted) print free # Model: USB Mass Storage Device (scsi)
2. Disk /dev/sdc: 7965MB# Sector size (logical/physical): 512B/512B# Partition Table: msdos

Number	Start	End	Size	Type	File system	Flags
	32,3kB	1049kB	1016kB		Free Space
1	1049kB	53,5MB	52,4MB	primary	fat32
2	53,5MB	1933MB	1879MB	primary	ext4
	1933MB	7965MB	6032MB		Free Space

we would like to resize the second partition to the nearly end ( -512MB for swap )

1. (parted) resizepart # Partition number? 2 # Warning: Partition /dev/sdc2 is being used. Are you sure you want to continue?# Yes/No? YES # End? [1933MB]? 7453MB this is how the partitions looks like after

(parted) print free * Model: USB Mass Storage Device (scsi)* Disk /dev/sdc: 7965MB* Sector size (logical/physical): 512B/512B* Partition Table: msdos

Number	Start	End	Size	Type	File system	Flags
	32,3kB	1049kB	1016kB		Free Space
1	1049kB	53,5MB	52,4MB	primary	fat32
2	53,5MB	7453MB	7400MB	primary	ext4
	7453MB	7965MB	512MB		Free Space

create Swap (optional)

(parted) mkpart primary linux-swap Start? 7453MB End? 7965MB

this is how the partitions looks like after

(parted) print free * Model: USB Mass Storage Device (scsi)* Disk /dev/sdc: 7965MB* Sector size (logical/physical): 512B/512B* Partition Table: msdos

Number	Start	End	Size	Type	File system	Flags

	7453MB	7453MB	278kB		Free Space
	7453MB	7965MB	512MB	primary	Free Space

disregard the 4th entry, the new resized partition is the last one.

resize filesystem

• resize2fs /dev/sdc2

create swap

• mkswap /dev/sdc3
