Hi, this is Linux-SWAT.
Welcome to the SL4P, Slackware for Pandora, Wiki pages.
SL4P is a Slackware ARM overlay.
Slackware ARM is the official ARM Slackware port.
Slackware ARM was formerly known as ARMedslack.
The 14.1 release forum page is located here: http://boards.openpandora.org/topic/15547-slackware-for-pandora-141/
The technical and -current forum page is located here: http://boards.openpandora.org/index.php?/topic/1524-slackware-inside-pandora/
I'm the maintainer of this Slackware port, and you can find me here: http://boards.openpandora.org/index.php?/user/1035-linux-swat/
If you have questions, I suggest you to share it on the boards, not asking me privately.

Older releases Wiki pages
- To keep this front page clean for the most recent release - 14.1 -, I moved previous versions elsewhere.
- The old page for the 14.0 release is located here.
- The old page for the 13.37 release is located here.
- ARMv5te, little endian, software float ("soft-float", "armel"), EABI.
Stable or -current ?
- Stable is for production use, ie. for work, as a server etc..
- -current is a work in progress. Although it's pretty usable, some things may be broken/unstable.
- I won't rebuild the OS if there's no big bad bug, I'll just add important features as packages. Of course, official Slackware updates are included.
- -current rootfs may be smaller or bigger from build to build, as I can include or remove KDE, amongst other things.
- If you want to help the development, I prefer that you use -current.
- And finally, -current repository may be empty. It's because a new stable release is out.
A word about SOLEIL
- SOLEIL is another project of mine, based on SL4P.
- It's basically the same OS from the Pandora point of view, but has some neat extended features. Feel free to take a look at it.
- SL4P runs on a SD card. It fits well on 8G, but 16G or more are recommended if you plan to install all the pre-compiled packages.
- The SD card must support Linux filesystems, see this SD compatibility chart.
- I myself recommend the SanDisk Extreme, Extreme PLUS, or Extreme Pro cards.
Note: if you're a Linux noob, and you're scared by this Wiki page, check this simple tutorial from F_Slim. Thanks to him.
Note: if you are one of the last windows users, you can install SL4P using the method nicely provided by ingoreis. Check this thread.
- 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. 512M is wiser is you plan to compile some stuff, or for server use.
- If you don't plan to use this partition configuration (OS followed by swap), you'll have to edit the /etc/fstab after having uncompressed the rootfs.
- If you're cleaning up a previous SL4P installation for a fresh new one, proceed like this:
rm -rf /media/SLACK/* rm -rf /media/SLACK/.cache/ rm -rf /media/SLACK/.keepdir/ rm -rf /media/SLACK/.splash/ rm -rf /media/SLACK/.subversion/ rm -rf /media/SLACK/.Trash-0/
then unmount, fsck and sync before plugging back the card.
- To do this, get the SD device name:
You will see something like:
/dev/sdc1 /media/SLACK ext2
- Unmount the partition:
then check the partition with fsck
fsck -y /dev/sdc1
- Grab the latest 14.1 rootfs here.
- Grab the latest -current (unstable) rootfs here. The -current repository may be empty. It's because a new stable release is out.
- Plug back the SD card to remount it.
- Uncompress the rootfs on your SD. Be root, using su -, or sudo:
sudo tar jxvfp SL4P-[version]-[build].tar.bz2 -C /media/SLACK/ --numeric-owner
- Be sure your Pandora's clock is set. Otherwise, your filesystem will be checked.
- Power down your Pandora, insert the SD card in the left slot (also called slot 1), and power on your unit.
- If you're prompted to enter the root password for maintenance or to type Ctrl-D, just wait, the unit will restart and check the filesystem automatically.
- 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.
- Then you'll be driven to the log in screen. Do not log in as the root user
Bug: very unlikely to happen, but when using startx (not the SL4P default setup), you can be blocked at a black screen. Use pandora button + power to reboot.
- The GDM login manager, which is SL4P's default, can automatically log in an user. You're asked about it at the first login. Else, use
to change the configuration.
- KDM works, but is too heavy. You have to edit /etc/rc.d/rc.4 in order to use it.
- Slim works, but now leads to unexpected results when using gksu, therefore was replaced by GDM for the 14.1 release.
- 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.
- To choose a window manager, type xwmconfig.
- I ship those:
Xfce fluxbox blackbox WindowMaker twm 9wm enlightenment17 jwm minimenu openbox wmii
- In some -current or -RC builds, i ship KDE. Avoid selecting it as full desktop on 256M Pandora.
- To power off, or reboot your Pandora when not in Xfce and its user-friendly menus, become root with:
Setting up your timezone
- Become root and use
Setting up your language
- You can set your locale pretty easily. First, you have to know which languages are available, type:
- Choose the one that best suits your need. I highly recommend to use the versions with .utf8 .
- Then be root and edit /etc/profile.d/lang.sh .
su - emacs /etc/profile.d/lang.sh
- You'll have to change this variable with the one you need:
- Save the file, make sure it's executable:
chmod +x /etc/profile.d/lang.sh
Services started at boot
- 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. For example, to activate the 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)
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 14.1 are already available here: http://slackbuilds.org/repository/14.1/
- I shipped a tool named sbopkg, which does the job for you. Become root using su - , then sync it with the internet repository with:
- The sync may take some time. Once you've done that, run
to optimize the builds for the Pandora. You have to run this script after every sync.
- Then all is set up, you just have to use
and choose "Local SlackBuild" when prompted.
- When the job is done, remove useless files to save disk space:
rm -rf /tmp/SBo/* rm -rf /var/cache/sbopkg/*
- Note that Slackware does not check dependencies, so you have to get the right build orders looking here: http://slackbuilds.org/
- To check if some of the dependencies are already installed in your system, look in /var/log/packages/ . For example, libgnomecanvas:
- 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 Slackware 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 (450+) of packages from http://slackbuilds.org/.
- I shipped a graphical install tool named GSlapt. Launch it with its icon, update the package list, then install what you need, checking the dependencies of your programs here: http://slackbuilds.org/
- You can also proceed manually. Find 14.1 packages here, and -current ones here.
- Download what you need, checking the dependencies of your programs here: http://slackbuilds.org/
- Put all needed .tgz or .txz in a folder, go root using su -, then type:
- Please report any non-working package.
About SL4P precompiled archives
- All shipped and extra archives are compiled with sbopkg with Pandora-optimized flags.
-DPANDORA -O2 -pipe -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -fPIC
- The links to the sources are located here: http://slackbuilds.org/repository/
- The building order is fixed in queue files, kind of build playlist.
- The queues are located in /var/lib/sbopkg/queues/
- About shipped archives (base and base-more), you don't need to download them as they're already in the rootfs, see this.
- Some archives won't work, like Kompozer, because it's a repackaging of x86 binaries. As I'm not yet in the process of fine-tuning, I left them for now.
Installing KDE 4
- Plug the net, become root using su -, then type:
slackpkg update slackpkg install kde
- Note that although i already slimmed down KDE configuration files for less eye-candy, a 512M Pandora is recommended to run the full desktop.
- Anyway, you can run any KDE application (konqueror, kwrite...) flawlessly with the 256M version running Xfce.
- Type xwmconfig to select KDE, or any other window manager.
- You may eventually read the Slackware ARM 14.1 changelog here
- If you need an up-to-date security, you should consider subscribing to the main Slackware mailing list. Slackware ARM updates are generally available a bit later.
- For stable releases, plug the net, become root using su -, then type:
slackpkg update slackpkg upgrade-all
- Do not use slackpkg when using a -current. Instead, look at the changelog, download packages from here, become root using su -, then type:
Note that some packages like a/aaa_elflibs are not supposed to be upgraded in -current. A new rootfs is needed.
- You can eventually set up a cronjob. In this case, check /etc/slackpkg/blacklist to ensure some critical packages (e.g. kernel) will not be updated.
- Slackware usually provides updates during 10+ years, but it seems to be less with Slackware ARM. See the news for more details.
- I provide Pandora fixes, available as Slackware archives.
- Simply use GSlapt, and update.
Firefox, Thunderbird, SeaMonkey and Java-OpenJRE/JDK updates
- Slackware ARM 14.1 doesn't provide anymore updates for Firefox, Thunderbird and SeaMonkey because of a build problem.
- You have to download the unsupported -current archives and update them manually, using the method mentioned above.
- Get them here.
- About Java-OpenJRE/JDK, it's not possible to update them through slackpkg because it was added on-the-fly to Slackware ARM.
- Check and get the updates here.
- Be sure to download and update both as the jre is not included in the jdk.
- I provide kernel updates through GSlapt.
- Many kernels are already available in the rootfs, like real time, or non-debug.
- To know which kernel is currently running, type:
- To enable a new kernel, for example 3.2.30-szfinal or the 3.2.26-rt, do:
cd /boot rm uImage cp uImage-3.2.30-szfinal uImage
cd /boot rm uImage cp uImage-3.2.26-rt uImage
- If lsmod reports that no modules are loaded (that means, eg., no touchscreen), then run as root:
And reboot again.
Automounting a SD card or an USB drive
- No system-wide automounter is enabled for now.
- Only Xfce and some other window managers do automount.
- As Xfce mounts devices at insertion, if you booted with a second SD card or an USB drive plugged in, you have to click on the device icon.
- 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:
USB at boot, suspend and powersaving
- Usually, you have to click on the Xfce "Toggle USB Host" icon whenever you need USB support.
- I disabled the USB support by default. As said Notaz, it "Uses around 3x more power when idle, fails to suspend properly.".
- If you want to enable USB host and USB networking support at boot, be root and edit /etc/rc.d/rc.local .
Near the top, change
Fixing the endless reboot
- Be sure your Pandora's clock is set. Boot Official Pandora OS on the NAND, and check/set time.
- Boot SL4P, when prompted to enter the root password for maintenance, do it, then type:
fsck -y /dev/mmcblk0p1
- You can do the same under Zaxxon. Note that it will be /dev/mmcblk1p1 if SL4P is on a second card.
- You will be warned if the card is still mounted, so unmount it, and proceed.
Changing the Hostname
- See this.
Switching from 1GHz to 600MHz Pandora
- I slightly modified the clock script to split the parameters into two categories: 1Ghz and 600MHz.
- You can safely put SL4P in any OP, and have a max OPP + max MHz settings for each as the model is recognized at boot, then clocked.
- It's totally transparent, just set your parameters as usual.
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.
SGX drivers installer
- With notaz's blessing, i tweaked his SGX drivers installer to make it work both under SL4P and Zaxxon.
- Get it here.
- You can safely remove your old version.
PND compatibility list
- SL4P supports .pnd files.
- PNDs used to be recognized automatically. It's not the case anymore, and I don't know why.
- So here's the workaround: after the insertion of your SD or USB drive, you have to push the green button near the Xfce menu.
- Due to 3.2 kernel and dynamically linked libraries, not all .pnd are compatible.
- View the PND compatibility list here.
- I wrote some tutorials to do interesting things.
- All those guides are applicable to any version of Slackware, ie. x86, x86_64, IBM mainframe, etc.
- Follow this link.
- See the build system, below.
- 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 three bash scripts.
- You need a Pandora to run the third 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.
- Available here.
