October updates for the Slackware Plasma5 desktop

There’s been updates to all the major components of the KDE Software Collection (I know they stopped using that name but I think it is still fitting). So I tasked my build box to compile hundreds of new packages and today I have for you the October ’17 set of Plasma 5 packages for Slackware 14.2 and -current. KDE 5_17.10 contains: KDE Frameworks 5.39.0, Plasma 5.11.0 and Applications 17.08.2. All based on Qt 5.9.2 for Slackware-current and Qt 5.7.1 for Slackware 14.2.
NOTE: I will no longer be releasing Plasma 5 packages for 32bit Slackware 14.2.

What’s new in the October release

There was a new Qt5 release just after my September packages, so this time the ktown repository comes with a ‘qt5‘ 5.9.2 package for Slackware-current.
The other major update is Plasma which had its first 5.11 release with lots of visual, UX and under-the-hood improvements. You can read the release announcement if you are curious. Most notable is a new functionality called “Plasma Vault” which enables you to add documents to an encrypted vault and hide that from sight. It’s not (yet) functional in my repository because plasma-vault depends on an external encryption program to do the job – and neither of the two candidates are part of Slackware or any of my own repositories. Install either ‘encfs‘ or ‘cryfs‘ to make this work.
The Frameworks and Applications updates are targeting stability and bugfixes.

I was unable to update KDE Partition Manager on Slackware 14.2, because its dependency ‘kpmcore‘ needs a newer ‘blkid‘ program than what’s available through the util-linux package. No problem for Slackware-current, it sports the latest ‘partitionmanager’ package.

I ran into an issue when I tried adding SDDM 0.16.0. SDDM is the graphical session manager aka login manager. It turns out that the new release is not compatible with ConsoleKit2 (which we have in Slackware) because the new code was only tested against systemd. Therefore I stuck with the 0.15.0 release which I know works well. We’ll just wait for a bug-fix release 0.16.1.

Installing or upgrading Frameworks 5, Plasma 5 and Applications

As always, the accompanying README file contains full installation & upgrade instructions.

Recommended reading material

There have been several posts now about KDE 5 for Slackware-current. All of them contain useful information, tips and gotchas. If you want to read them, here they are:

Where to get the new packages for Plasma 5

Package download locations are listed below (you will find the sources in ./source/5/ and packages in /current/5/ and  /14.2/5/ subdirectories). Only “bear” has the packages for now, the mirrors should follow within 24 hours. If you are interested in the development of KDE 5 for Slackware, you can peek at my git repository too.


A new Plasma5 Live ISO image (based on liveslak has been uploaded to in case you want to try the new Plasma5 desktop out first in a non-destructive way.

Have fun! Eric

Updates for LibreOffice, Pale Moon, Flash

I have some updates for you while I am working on a new Plasma5 package set.

The LibreOffice packages were uploaded to my repository last Friday, so you probably already have that installed. Never hurts to mention it for those people who did not subscribe to my RSS feed.

Here is a screenshot of the upcoming Plasma5 desktop release, to keep you sharp:

Refreshed ISO’s for Slackware Live Edition, and more

blueSW-64pxWhen I released new Live ISO images almost two weeks ago, a bug in the init script which became apparent with the latest Slackware initrd broke the encrypted /home feature. Therefore I am releasing an updated set of ‘liveslak‘ scripts with version .

The latest set of Slackware Live Edition ISOs are based on liveslak and Slackware-current dated “Fri Sep 29 22:58:54 UTC 2017“). That means, the new Live ISOs contain the updates to TexLive and Python3 (well, no texlive in the XFCE image due to its size limit of course).

If you already use a Slackware Live USB stick that you do not want to re-format, you should use the “-r” parameter to the “” script. The “-r” or refresh parameter allows you to refresh the liveslak files on your USB stick without touching your custom content. If you want to modify other parameters of your USB stick, use the script ““. It’s main feature is that it can update the kernel on the USB stick, but it also can replace the Live init script. As with most (if not all) of my scripts, use the “-h” parameter to get help on its functionality.

And more:

I built new versions for the palemoon packages for Slackware 14.2 and -current to the latest 27.5.0 version. Someone stated he had issues compiling on slackware-current so I made sure the palemoon.SlackBuild works. The new palemoon package is included in the refreshed PLASMA5 Live ISO image. Note that to compile this on slackware-current you will need my gcc5 package; this software cannot be built with gcc6. Before starting the compile, source the gcc5 profile script:
“. /etc/profile.d/” – note the dot.

I updated the Chromium package as well.
Chromium had a recent bugfix upgrade to 61.0.3163.100 which I missed initially.


And even more:

The recent flurry of activity in the Slackware-current development tree (boost, poppler, python3), caused repeated broken-ness of my own packages. The collection of multilibcompat32” packages was renewed several times. I recompiled LibreOffice 5.4.1 for slackware-current and in my ‘ktown‘ repository for Plasma5 there were multiple updates. I did manage to ‘sneak in’ new versions for Krita and KDEConnect at the same time. This too is all part of the refreshed PLASMA5 Live ISO image.

liveslak 1.1.9 and new ISO images

blueSW-64pxThe ‘liveslak‘ scripts used to create the ISO images for Slackware Live Edition have been stamped with a new version, 1.1.9. The updates are significant enough to warrant an ‘official’ update and new ISO images.

The latest set of Slackware Live Edition ISOs are based on liveslak 1.1.9 and Slackware-current dated “Tue Sep 19 20:49:07 UTC 2017“. Just in time (I was already creating ISOS based on -current “Mon Sep 18 19:15:03 UTC 2017“) I noticed that Patrick downgraded the freetype package in Slackware, and I re-generated all of the ISO images to incorporate the latest freetype package – because that one is working and the previous one had serious issues.

If you already use a Slackware Live USB stick that you do not want to re-format, you should use the “-r” parameter to the “” script. The “-r” or refresh parameter allows you to refresh the liveslak files on your USB stick without touching your custom content.

I should note (I always seem to forget mentioning this) that there’s also a “bonus” section where you can find a couple of Live squashfs modules that are included in the PLASMA5 Live ISO, and that will be just as useful to people who don’t want to run Plasma 5. These modules can be copied to the /liveslak/addons/ directory of your USB Live stick so that they are automatically loaded on every boot. The “bonus” section contains modules for:

  • broadcom-sta (“wl” module for 4.9.50 kernel) for people whose BCM wireless card does not work out of the box
  • multilib (gcc, glibc and the full set of compat32 packages)
  • skypeforlinux
  • wine (with OpenAL-compat32 already incorporated)

New in the ISOs

The new ISOs are based on the latest Slackware -current with Linux kernel 4.9.50, gcc 7.2.0, glibc 2.26 and X.Org 1.19.3.

The SLACKWARE variant contains the complete latest slackware-current distribution and nothing else. Ideal for testing and for checking out the progress of Slackware’s development.

The XFCE variant contains a stripped down Slackware with a minimalized package set but still quite functional. The small size is also accomplished by excluding all documentation and man pages, and the localizations for the languages that are not supported in the boot menu. This ISO is small enough that you can burn it to a ’80 minutes’ CDROM (700 MB). Ideal for hardware compatibility tests.

The MATE variant (a Slackware OS with KDE 4 replaced by Mate) contains packages from the repository at which at this moment gives us Mate 1.18.

The PLASMA5 variant (Slackware with KDE 4 replaced by Plasma 5) is a showcase for the latest Plasma 5 release “KDE-5_17.09” as found in my ktown repository. Additionally you will find several packages from my regular repository: chromium (with flash and widevine plugins), vlc, ffmpeg, libreoffice, palemoon, calibre, qbittorrent, openjdk and more. This ISO also contains the LXQT and Lumina Desktop Environments. Both are light-weight DE’s based on Qt5 so they look nice & shiny.

The liveslak scripts support three more variants out of the box: CINNAMON (a Gnome3 fork), DLACKWARE (slackware with systemd) and STUDIOWARE (a toolbox for musicians). There’s no ISO image for the Cinnamon and Dlackware variants this time. The Studioware Live ISO can be downloaded from .

What happened between liveslak 1.1.8 and 1.1.9

For your information, a few ‘micro’releases were issued inbetween 1.1.8 and 1.1.9, to accompany the upload of ISO images for Plasma5. These micro-releases did not really add functionality.

  • Support booting from a SD card.
  • Allow syntax ‘livemedia=scandev:/path/to/live.iso’.
    With the ‘scandev’ keyword, liveslak will search for the ISO on all local partitions.
  • Added two new option parameters to the ‘’ script: “-l” to list and “-d” to scan for the insertion of removable devices on the local computer.
  • A new script has been added: ‘’.
    This script is primarily meant to be run from within your Slackware Live environment, but with the exception of the “-p” option  – see below – it works just as well on your harddisk installation of Linux and with the USB Live stick inserted into the computer. Upslak can tweak your Slackware Live USB stick in several ways:

    • Update the boot kernel & the kernel modules inside the initrd image using the “-k” and “-m” options.
      You can provide Slackware packages as input to these option parameters, or else a single kernel file and a module-tree in /lib/modules/ are also accepted.
      Note that this will leave alone the kernel and the modules inside the Slackware Live filesystem. You can update the kernel-generic and kernel-modules packages in the Slackware Live OS using the regular Slackware package tools if you wish… but the USB stick will not use those anyway.
      Note: this kernel/modules replacement can be reverted if it turns out your new kernel is not working: using the “-r” option. Your previous kernel & modules are backed up by ‘’.
    • Replace the live init script using the “-i” option.
      There are two reasons you would want this: (1) you re-wrote the init script and want to start using that, and (2) you saw that there is a newer version of the “liveinit.tpl” template and want to use that as your new Slackware Live init script.
    • Create an ‘addon’ squashfs module out of the persistent data store using the “-p” option.
      Your persistent data grows over time, and a lot of that may be caused by packages that you install on top of Slackware Live. Using this option you can create a new squashfs module which will be placed in the /liveslak/addons/ directory so that it will be loaded on every boot of the Live OS. The content of the persistent store will be moved into that squashfs module and then the persistent store will be re-initialized (i.e. wiped clean).
      You can repeat this ‘persistence-to-module’ activity as many times as you like.
    • Change the USB wait time on boot, quite similar to the “-w” option of ‘’.
    • Add network modules to the initrd using the “-n” option.
      This should normally not be needed, all ISO images of the Slackware Live Edition have network support included out of the box. But in case of a custom Live USB where network support was initially omitted, this could come in handy if you want to PXE-boot the Live OS.
  • And other small improvements/bugfixes to the scripts.

Download the ISO images

The available ISO variants for Slackware Live Edition are: SLACKWARE (64bit & 32bit), XFCE (64bit & 32bit), PLASMA5, MATE. These ISO images (with MD5 checksum and GPG signature) have been uploaded to the master server (bear) and should be available on the mirror servers within the next 24 hours.

Updates for Chromium, LibreOffice, Calibre (and Flash too)

I took my new build server for a run and have not found its limits yet (plus, no Ryzen related crashes yet). Compared to my old computer, this new box compiles with roughly 10 times the speed. That makes a big difference for big updates like Chromium and LibreOffice, which would take me one day per package (i.e. per release and per architecture) in the past.

I can now effortlessly run 3 VM’s in parallel, all with 8 virtual cores and 8 GB of RAM. That will of course slow down compiling a bit (4 to 5 times the old speed instead of 10 times) but with 3 virtual machines I still get a lot more output than ever before.

Therefore, I have been able to create and upload new packages (Slackware 14.2 and -current):

And added to the stew: today’s Adobe Flash security updates, which give us version of the Flashplayer for Chromium and Mozilla browsers.

Have fun! Eric
