Hi, this is Linux-SWAT.

Welcome to the SL4P, Slackware for Pandora, Wiki page.

The technical forum page is located here: http://boards.openpandora.org/index.php?/topic/1524-slackware-inside-pandora/

The 13.37 release page is located here: http://boards.openpandora.org/index.php?/topic/7574-rebirth-competition-slackware-for-pandora-pre-release-thread/

I'm the maintainer of this Slackware port, and you can find me here: http://boards.openpandora.org/index.php?/user/1035-linux-swat/

SL4P is an ARMedslack overlay. ARMedslack is the official ARM Slackware port.

This software is distributed as is. You are on your own responsibility when using it.

Installation

• Format a 8G or more SD card with the Ext2 filesystem. To make explanations clear, name it SLACK.
• If you don't know how to format a drive, use GParted under Linux, or run their Live-CD. Here's the manual.
• It's highly recommended to have a second partition formated as a swap. 256M or more is a good choice.
• Grab the latest rootfs here: http://
• Uncompress the rootfs on your SD. Be root, using su -, or sudo:

sudo tar -jxvfp myrootfs.tar.bz2 -C /media/SLACK/ --numeric-owner

First run

• Be sure your Pandora's clock is set. Otherwise, your filesystem will be checked.
• Power down your Pandora, insert the SD card in slot 1, and power on your unit.
• You will be prompted to choose a password for the root user.
• You will be prompted to create an user. At some explicit point, push up to put this user in adequate groups.
• You will be prompted to choose your desktop environment.
• When you log in as an user, the desktop environment is automatically launched.
• To disable this feature, remove your .bash_profile, or comment the startx command in it.
• Note: connecting with ssh will also launch startx. You can use Ctrl+C to kill it in a very dirty way ^^.

Last minute bug: after login, you can be blocked at a black screen. Use pandora button + power to reboot. Working on this.

Basic usage

• In order to type commands as root, you have to type su -. You can use just su, but i don't recommend it because you won't have the full root environment.
• In order to unmount drives or SD cards under Xfce, you have an icon in the bar. You can also manually use pumount as user.
• Power button is disabled for now, so you won't crash your system putting it in ram suspend.
• When using adduser, at some explicit point, push up to put this user in adequate groups.

Basic tools

• To upgrade, plug the net, become root using su -, then use slackpkg update, followed by slackpkg upgrade-all.
• To enable or disable services at boot, become root, then type pkgtool, then go in setup -> services, check the option with space then push enter.
• Some services are not listed here. To activate nfs server permanently, tweak /etc/exports and /etc/hosts.allow, then:

 chmod +x /etc/rc.d/rc.nfsd
 /etc/rc.d/rc.nfsd start (not needed after a reboot)

• To choose a window manager, type xwmconfig.

Installing a program - Tools

• Slackware archives are .tgz or .txz
• Slackware uses three powerful tools: installpkg, removepkg and upgradepkg.
• A fourth tool named makepkg build packages from compiled sources.

Installing a program from source

• The cleanest way to do it is to use a SlackBuild script: http://slackbuilds.org/guidelines/
• Many SlackBuilds for Slackware 13.37 are already available here: http://slackbuilds.org/repository/13.37/
• I shipped a tool named sbopkg, which does the job for you. Become root using su -, then run sbopkg.
• Note that Slackware does not check dependencies, so you have to get the right build orders looking here: http://slackbuilds.org/
• Also note that gnome libraries must be compiled in a certain order. I already did the job, and shipped them in the rootfs.
• If you don't use a SlackBuild script, then the procedure almost always ends like :

make install DESTDIR=/tmp/whatever/
cd /tmp/whatever/
makepkg /tmp/whatever-1.0.0-arm-1.tgz
installpkg /tmp/whatever-1.0.0-arm-1.tgz

Installing a program with a precompiled archive

• I compiled a lot of packages from http://slackbuilds.org/. You can find them here: http://
• Download what you need, checking the dependencies for your version here: http://slackbuilds.org/
• Put all needed .tgz or .txz in a folder, go root using su -, then type:

installpkg /path/to/your/folder/*.t?z

Updates

• Plug the net, become root using su -, then type:

slackpkg update
slackpkg upgrade-all

• Slackware usually provides updates during 10 years.

SL4P-specific updates

• I provide Pandora fixes, available as Slackware archives.
• 13.37 fixes are located here: http://
• Grab them, become root using su -, then type:

upgradepkg /path/to/the/updates/*.t?z

Installing KDE

• Plug the net, become root using su -, then type:

slackpkg update
slackpkg install kde

• Note that although i already slimmed down KDE configuration files, the 512M Pandora is recommended to run the full desktop.
• Anyway, you can run any KDE application (konqueror, kwrite...) flawlessly with the 256M version.

Fast boot tweak

• I moved some of the boot stuff (ldconfig, font cache, mime database) in /etc/rc.d/rc.local_shutdown.
• The reboot/power off process is slowered, but the OS integrity is safe.

Autologin

• As i didn't succeded to compile the Slim display manager, no clean auto logger is available at this time.
• KDM works, but is too heavy. You have to edit /etc/rc.d/rc.4 in order to use it.

PND compatibility list

• SL4P supports .pnd files.
• Due to 3.2 kernel and dynamically linked libraries, all .pnd are not compatible.
• The list is located here: http://pandorawiki.org/Software_projects/OS/Slackware/PND-compatibility-list

Build system

• I distribute it under the GPL 3 license.
• It may look a bit messy for now (and indeed, some part have to be cleaned), but it's versatile, as i intended from the start.
• It's mainly two bash scripts.
• You need a Pandora to run the second one.
• Depending on what you comment/uncomment, you can produce an alpha build, very minimal, or a full build.
• Depending on what you edit, you can use it to port any *NIX to Open Pandora, and maintain your build very easily.
• Get it here, along the more detailed instructions.

Automounting a SD card or an USB drive

• No system-wide automounter is enabled for now. It's still a wip and not perfect so i don't include this for now.
• Only Xfce automounts.
• As Xfce mounts devices at insertion, if you booted with a second SD card or an USB drive plugged in, you have to remove, then plug back the device.
• If you plan to use Minimenu, you currently have to automount under Xfce, run xwmconfig, then log out to run Minimenu. This is the best method to save RAM.
• You can also launch Minimenu under Xfce. Open a terminal and type:

mmwrapper -fmmenu

Xfce layout chooser

• The icon is located in "System".
• I'm developing it, it's currently in beta stage.
• You can save your own Xfce configuration, and load others.
• If you want to use it, please use the save feature prior to anything else.
• Only one custom layout is available right now.
