My thoughts on Slackware, life and everything

KDE: February 2024 MegaRelease

Just a heads-up to you people who wondered when Alien BOB would pick up on the KDE Plasma bleeding edge again.
Simply put: Patrick did a hell of a job pushing every new KDE Plasma update into the slackware-current package tree (even before the 15.0 release) in no time. There was nothing for me to do (or to improve on) since Plasma5 got added to the distro.

My intention is to change that, soon.

Exactly one month ago, KDE published their planning for Plasma6, the successor to Plasma5, so numbered after the version of the Qt framework which underpins it. As seen on the ‘February 2024 MegaRelease‘ page, the first Alpha release of the Qt6-based Frameworks, Plasma and Gear (the three main components of KDE Plasma) is expected to see the light on November 8th, 2023. The final stable release of KDE Plasma6 will be on February 28th, 2024.

I don’t expect that Slackware itself will absorb this new software immediately upon release. Perhaps we will have a Slackware 15.1 next February, maybe not – but a new KDE desktop is a major and potentially disruptive upgrade. Still, it needs solid testing on Slackware -current somehow. Therefore I will have that stable KDE Plasma6 in my ktown repository when it is released.

I am currently working on updating the kde.SlackBuild infrastructure which I took from Slackware-current, to make it work with the new Plasma6 sources. It is not a trivial task; there are new non-KDE dependencies, new KDE programs and changed interdependencies, patches to remove and patches to add.
So far, I have finalized the scripts for all of the new dependencies, as well as the Frameworks and Plasma. Currently working on KDEPIM, and then the Gear collection (formerly called Applications) awaits. The results up to now took me a full week, and the Gear will probably have the same level of unpleasant surprises (hey, it won’t compile! what did they sneak in now? <initiates another search through KDE Invent>…).

Meaning, I won’t make promises on the timeline for a first Slackware-based test release. I aim to make it coïncide with KDE’s own Alpha release, but I may not be able to finish on time. To be clear about my roadmap: anything that I make available before the stable release of Feb 28, will take the shape of a Slackware Live ISO image (the ktown variant, we haven’t seen that one for two years almost!) for you to test and play with.
There will be no new packages in the ktown repository until the time when KDE Plasma6 stable gets released. I am supportive of people who want to compile this set themselves, so I will make the sources available in ktown as soon as I release the first live ISO and will keep updating those sources.

Note that I will not make Plasma6 co-installable with Plasma5. It’s going to be one or the other. Any official Slackware package that I have to recompile to add Qt6 support, will not lose its Qt5 support. Meaning, my ktown versions of gpgme, kdsoap, phonon, polkit-qt-1, poppler, qca, qcoro or qtkeychain will be 100% compatible with standard Slackware.

Hope to have more news in a week or two!

KDE 5_15.07 – July release for Slackware-current

Plasma5_lockedpowerpenguin Today my son had his last day at school – holiday time! We had little hope he would pass his semi-final year at the “middelbare school” but he managed to pull of a small miracle and passed anyway. Yay! His dad will sleep better now… and I used the relaxed mood to sit behind this computer and write a blog post about the July release of KDE 5 for Slackware-current. While my son went out to party, we slackers just install the latest and greatest software and pound it hard to see if any bugs seep out of the cracks.

The past month saw various KDE component releases which I let slip, because I intend to offer upgrades only when newer versions of all of Frameworks, Plasma and Applications are available. Well, there was Frameworks 5.11.0 several weeks ago but I skipped that one entirely, and today Frameworks 5.12.0 was released. The KDE Applications 15.04.3 release was already more than a week ago, and Plasma 5.3.2 one day before that, on 30 June.  Time for some package building, and because the Frameworks sourcecode was made available to packagers a number of days ago, I had them ready on wednesday… but needed to wait for the public release of the new Frameworks.

Now then, my July release of the next-gen KDE for slackware-current: KDE 5_15.07. Its main components, as said earlier, are Frameworks 5.12.0, Plasma 5.3.2 and Applications 15.04.3. The updates to Applications also contain the usual KDE 4 Long Term Support (LTS) updates for kdelibs, kdepimlibs, kdepim, kdepim-runtime and kde-workplace. Hopefully Pat will fold those LTS releases back into the official KDE 4 for Slackware-current.

What’s new in KDE 5_15.07?

Well… probably all sorts of improvements under the hood of the various packages, but nothing exciting jumps out that I feel compelled to tell you about. Overall, more stability and less bugs, let’s hope. Read the Release Notes and you’ll know it all. Hey, weekend ahead! Time is on your side.

Installing or upgrading Frameworks 5, Plasma 5 and Applications

As always, the accompanying README file contains full installation & upgrade instructions. Note that the packages are available in several subdirectories below “kde”, instead of directly in “kde”. This makes it easier for me to do partial updates of packages. The subdirectories are “kde4”, “kde4-extragear”, “frameworks” “plasma”, “plasma-extra” and “applications”.

Upgrading to this KDE 5 is not difficult this time, especially if you already are running KDE 5_15.04 or later. You will have to remove old KDE 4 packages manually. If you do not have KDE 4 installed at all, you will have to install some of Slackware’s own KDE 4 packages manually.


If you are using slackpkg+, have already moved to KDE 5_15.01 or newer and are adventurous, you can try upgrading using the following set of commands. This should work but feel free to send me improved instructions if needed (assuming in this example that you tagged my KDE 5 repository with the name “ktown_testing” in the configuration file “/etc/slackpkg/slackpkgplus.conf“):
# slackpkg update
# slackpkg install ktown_testing (to get the newly added packages from my repo)
# slackpkg install-new (to get the new official Slackware packages that were part of my deps previously)
# slackpkg upgrade ktown_testing (upgrade all existing packages to their latest versions)
# slackpkg upgrade-all (upgrade the remaining dependencies that were part of my repo previously)
# removepkg sddm-theme-breeze (gone after KDE 5_15.01)
# removepkg libmm-qt5 (gone after KDE 5_15.03)
# removepkg qt-gstreamer0 (gone after KDE 5_15.04)
# slackpkg reinstall qt-gstreamer (ensure that none of the overlapping files of qt-gstreamer0 are left)
# slackpkg reinstall kactivities-framework (ensure that you are using the frameworks version of kactivitymanagerd)

And doublecheck that you have not inadvertently blacklisted my packages in “/etc/slackpkg/blacklist“! Check for the existence of a line in that blacklist file that looks like “[0-9]+alien” and remove it if you find it!

Recommended reading material

There have been several posts now about KDE 5 for Slackware-current. All of them contain useful information, tips and gotchas that I do not want to repeat here, but if you want to read them, here they are:

A note on Frameworks

The KDE Frameworks are extensions on top of Qt 5.x and their usability is not limited to the KDE Software Collection. There are other projects which rely (in part) on the KDE Frameworks, and if you are looking for a proper Frameworks repository which is compatible with Slackware package managers such as slackpkg+, then you can use these URL’s to assure yourself of the latest Frameworks packages for Slackware-current (indeed, this is a sub-tree of my KDE 5 “testing” repository):

Where to get the new packages for Plasma 5

Download locations are listed below (you will find the sources in ./source/5/ and packages in /current/5/ subdirectories). If you are interested in the development of KDE 5 for Slackware, you can peek at my git repository too.

Using a mirror is preferred because you get more bandwidth from a mirror and it’s friendlier to the owners of the master server!

Have fun! Eric

Updated KDE 5 packages for Slackware (release 5_15.02_02)

qt-kde-620x350Earlier this week I grabbed the new Plasma source tarballs and used them to update my ‘ktown’ package set for KDE 5. I tagged that update “5_15.02_02” to indicate that this is my second release in Feb 2015.


Some more highlights of this incremental release are:

  • Plasma has been upgraded to 5.2.1, this is a bugfix release. No new functionality or packages.
  • The deps/libssh package has been re-added. I used it for my KDE 4.14.x packages because the newer version (compared to Slackware’s version of the package) allows the sftp kioslave to be compiled in kde-runtime.
  • The kde/applications/kde-runtime package has been recompiled against the newer libssh package.
  • And kde/frameworks/kglobalaccel was also rebuilt. The kglobalaccel5 deamon moved from plasma-workspace-5.2.0 into kglabalaccel-5.7.0, but when I built kglobalaccel with plasma-workspace-5.2.0 present it picked up a dependency on that package’s library. When I upgraded to Plasma 5.2.1, that library was suddenly gone and kglobalaccel5 would no longer start.

Installing or upgrading to KDE 5

As always, the accompanying README file contains full installation & upgrade instructions. Note that the packages are available in several subdirectories below “kde”, instead of directly in “kde”. This makes it easier for me to do partial updates of packages. The subdirectories are “kde4”, “kde4-extragear”, “frameworks” “plasma”,  “plasma-extra” and “applications”.

Upgrading from Slackware’s KDE 4 to this KDE 5 is non-trivial. You will have to remove old KDE packages manually. If you do not have KDE installed at all, you will have to install some of Slackware’s own KDE 4 packages manually. If you are upgrading from KDE 5_15.02 then it’s an easy and painless upgrade, in particular when using slackpkg+.

If you are completely new to KDE 5 for Slackware, I urge you to also read my previous posts about KDE 5_15.01 and KDE 5_15.02 in its entirety, as well as the follow-up article about  the changes in system tray support in the Plasma 5 desktop which is mandatory reading material as well if you are using Dropbox, Skype and other non-Plasma 5 software that wants to dock an icon in the system tray.

Using the KDE Frameworks 5 separately

Someone mentioned in a comment to an earlier blog post that LxQt 0.9 uses some of the KDE Frameworks, now that they have migrated from Qt 4 to Qt 5.

To accommodate Slackware users who want to run that version LxQt I have added repository definition files to the frameworks package directories, so that you can use the Frameworks package repository even if you do not want to install KDE 5.

Use either one of these URL’s in your package management tool such as slackpkg+ for the Frameworks repository:

KDE 5 (Plasma 5.2.0) available for Slackware -current

qt-kde-620x350And yes – let me get this clear right from the start: this Plasma 5.2.0 desktop environment will replace the KDE 4 packages you have installed.

What is this new ‘Plasma 5’

Plasma 5 is the “next-gen” KDE desktop. It has been in development for a long long time, with the goal of providing a gradual migration path away from the well-known KDE 4 desktop. All of this with the KDE 4.0 “debacle” in mind. You may recall that the KDE community released KDE 4.0 as a “tech preview” i.e. not ready for production, however some distributions upgraded their KDE from 3.x to 4.0 regardless of that. The backlash from the user community was understandable of course, because they went from a stable KDE 3 desktop to a buggy and crippled KDE 4 desktop. This was often blamed upon KDE itself, but that does the developers and their software grave injustice – it was the distros who forced their users to a non production-ready version of KDE,so it should be those distros who should be criticized for their bad judgement. Still, even to this day, harsh words about KDE 4.0 are targeted at its developers, not at the distros who made a strategic error.

Nevertheless, here we are, with a shiny KDE 5 desktop environment!

KDE 5 makes a switch from Qt 4 to Qt 5 as the base graphical toolkit. The old KDE 4 libraries have been ported to become the Frameworks: Qt 5 modules with no dependencies except Qt 5 and optionally, other Frameworks. This allows non-KDE developers to adopt the Frameworks in order to provide an expanded Qt 5 feature set. This porting effort has been going on for a long time now (its first technology preview for Frameworks was little more than one year ago) and the Frameworks are mature technology now. Plasma 5 is the set of packages that provide the core Desktop experience, built on top of the Frameworks.

The release of Plasma 5.2.0 earlier this week was the turning point for me – this release is the first one that I actually consider ready for prime-time, capable of replacing the KDE 4 Workspace. The KDE Applications (currently at version 14.12.1) are the collection of software which used to be grouped in meta-packages like kdebase, kdeedu, kdegraphics, kdemultimedia etcetera. The Applications currently get huge attention from the developers, because that is where the hard work is being done the coming year. Slowly, all individual Applications are being ported away from Qt 4 and the KDE 4 libraries, to Qt 5 and the Frameworks. In Applications 14.12.1, the only ported apps to date are kate, konsole, analitza, gwenview, kalgebra, kanagram, khangman, kig, parley, kapptemplate,  and okteta. As you can see, still a long way to go.

These KDE 5 packages of mine are going to be your only KDE desktop. The “kde-workspace” package which provided the well-known KDE 4 workspace has been replaced by “plasma-workspace” and the good old KDM graphical login manager has been retired and replaced with SDDM. While you will be presented with a pretty Plasma 5 workspace, most of the KDE applications you’ll be using are the familiar KDE 4 versions (with updates and bugfixes), nicely blending in to the new Breeze theme.

Some Plasma 5 highlights I mentioned in last year’s preview: Plasma 5 improves support for high-DPI displays and comes with a “converged shell”, i.e. one Plasma codebase for different target devices like desktop computers, laptops, tablet, phones etc. Plasma 5 uses a new fully hardware-accelerated OpenGL(ES) graphics stack. And with the Breeze themed artwork and its own Oxygen font, this desktop looks clean and modern.

Plasma 5 follows the same trend you can also witness in Android 5, Windows 8 and OS X: gone are the colourful, exuberant 3D-ish icons, buttons and other graphical design elements.  Flat and monochrome is the new dogma. The result is too clean in some regards, is my personal opinion: the monochrome system tray icons are just plain ugly and I get flashbacks of Windows 3.1 sometimes. Judge for yourself.

What to expect from these Slackware packages

These packages are only going to be useful if installed on top of Slackware -current. They are replacing the KDE 4 packages (plus adding/upgrading a lot of dependencies) that you might have installed. There is no co-installable option. Therefore if you rely on your KDE desktop for your daily productive work, please consider your upgrade carefully. The upgrade/migration should be painless if you follow the README instructions, but I can not guarantee that there will be no deal-breakers for you (missing functionality or persistent crashes).


  • Lots of packages in the ‘deps’ department which are completely new to Slackware. Since KDE 5 is built on Qt5 (KDE 4 had Qt4 as its base) you’ll find many Qt5 related packages. Also, in order for Qt4 and GTK based applications to dock into the Plasma 5 system tray, more dependencies were needed. So, apart from updates to regular Slackware packages, these are the new ones (some of them will be familiar if you are already running my KDE 4.14.3):
    LibRaw, OpenAL, akonadi-qt5, eigen3, gst1-plugins-base, gst1-plugins-good, gstreamer1, json-glib, libappindicator, libdbusmenu-gtk, libdbusmenu-qt5, libepoxy, libfakekey, libindicator, orc, polkit-qt5-1, qca-qt5, qt-gstreamer, qt-gstreamer1, qt5, sni-qt, wayland and xapian-core.
  • Qt 4.8.6 of Slackware was patched to support the docking of Qt 4 application icons into the Plasma 5 system tray (and the ‘sni-qt’ package actually implements this support). While I was at it, I also added some patches which Libreoffice requires for native KDE file-open dialog support.
  • Note for users of multilib Slackware64 and also using Skype: you will have to grab the 32-bit version of Slackware’s “libdbusmenu-qt” and my “sni-qt” packages and run “convertpkg-compat32” on them and then install both “libdbusmenu-qt-compat32” and “sni-qt-compat32”, or else Skype won’t be able to dock its icon in the Plasma 5 systray.
  • A bit sneakily, I built phonon-vlc for you. You will also need a VLC package to be able to use phonon-vlc though.
  • I added the latest Calligra 2.8.7 office suite.
  • Even though I compile a ‘kde-workspace’ package as part of the whole set (otherwise kdeartwork refuses to compile), I do not actually ship that package. It conflicts with the new plasma-workspace package.
  • Several source tarballs in Plasma 5.2.0 have not been compiled to Slackware packages: libbluedevil and bluedevil (they need BlueZ 5 which is not part of Slackware), muon (a debian/ubuntu package manager), libkface (needs opencv which I was not willing to add as a dependency).
  • One dependency which you’ll probably find curious, is wayland. It is required in order to compile KWin’s X11 driver, but it is apparently not needed at runtime. Nevertheless, I left the package in, just in case you want or need to recompile kwin.
  • Graphical login: KDM has been replaced with SDDM. Installation of the sddm-qt5 package triggers the creation of a “sddm” user and group. The “sddm” user is then also added to the “video” group. If you already have a local “sddm” account, then all of that will be skipped. You’ll have to add the “sddm” user to the “video” group manually if you experience graphical glitches.

Testing Repository URL

I still consider KDE 4.14.3 the “latest stable” version for Slackware-current, and therefore the repository URLs (for 64-bit) and (for 32-bit) will keep pointing to KDE 4.14.3. You can use this repository URL for slackpkg+ or slapt-get or whatever package manager you use.

The URL (for 64-bit) and (for 32-bit) is pointing to my KDE 5 testing ground. I consider Plasma 5.2.0 as a “testing” release, with potential to be your next stable desktop, but with some caveats and reservations. The URL itself will remain permanent, even when the versions of the software components get updated. Currently “testing” points to version “5” in the repository because versions of Frameworks, Plasma and Applications are not co-ordinated and package updates may appear in the next months for these sub-sets. The “5” is a good middle ground. You should use this “testing” URL when you configure slackpkg+ or slapt-get if you want to upgrade to Plasma 5.

You must use only one of these URLs! I remind you that the KDE 5 preview I released last August was meant to be installed in parallel with KDE 4.14… but these new KDE 5 packages I am releasing today are going to replace the majority of KDE 4 packages. Therefore, the upgrade from KDE 4 to KDE 5 must be done manually, by closely following the provided README . Reading that README is even more important than before!

Enabling SDDM in runlevel 4 instead of KDM

Runlevel 4

If you want to see the new graphical session (login) manager SDDM in action, add the following lines to the Slackware file “/etc/rc.d/rc.4” right after the line: echo “Starting up X11 session manager…”

# — 8< ————————————–
if [ -x /usr/bin/sddm ]; then
exec /usr/bin/sddm
# — 8< ————————————–

… and then switch to runlevel 4 by typing at the command prompt (as root):

# init 4

Select “Plasma” from the SDDM session dropdown. Alternatively, if you prefer good old runlevel 3, you can type this at the command prompt (logged in under your own regular user account):

$ xwmconfig

… and select “xinitrc.plasma” as your default window manager for X11. Then run:

$ startx

To enter your desktop session.

Installing or upgrading Frameworks 5, Plasma 5 and Applications

As always, the accompanying README file contains full installation & upgrade instructions. Note that the packages are available in three subdirectories below “kde”, instead of directly in “kde”. This makes it easier for me to do partial updates of packages. The subdirectories are “kde4”, “frameworks” “plasma”,  “plasma-extra” and “applications”.

Upgrading to this KDE 5 is non-trivial. You will have to remove old KDE packages manually. If you do not have KDE installed at all, you will have to install some of Slackware’s own KDE 4 packages manually.

Where to get the new packages for Plasma 5

Download locations are listed below (you will find the sources in ./source/5/ and packages in /current/5/ subdirectories). Using a mirror is preferred because you get more bandwidth from a mirror and it’s friendlier to the owners of the master server!


  • In earlier preview release, HPlip would show an error message about not finding a system tray area. The reason is because the Plasma 5 workspace does not implement the X11 “Xembed” protocol. The system tray area works differently now. Not just HPlip, but all other applications that are not part of  Plasma  5, would have this issue, but only HPlip shows an error. Therefore some additional work was required to make the icons for Dropbox, Skype, Chromium, etc show in the Plasma 5 systray. This was done in the form of several notification support packages in the “deps/” directory and a patched Qt 4.
    • There is a solution for applications like SCIM who still can’t show a systray icon even with these added packages –  which is not elegant, but it works. Use a third-party Xembed system tray implementations like stalonetray or wmsystemtray . I have stalonetray and wmsystemtray in my own repository (I like wmsystemtray better). Both are also available at SBo.
  • Certain conditions may crash your Plasma Shell. I noticed this in a QEMU virtual machine where it was reliably reproducible: The crash occurs every time you move your mouse pointer into an Application Window placeholder in the taskbar. A crash of plasmashell makes your desktop go black and you are left with only the application windows that were currently open. Automatic restart should happen, but not for me unfortunately. You can fix it if you had a Konsole window open at the time of the crash. Type “plasmashell –shut-up &” and your desktop will re-appear.
  • The updated harfbuzz package breaks the library’s ABI. As a result, LibreOffice 4 will no longer work (error looks like “symbol lookup error: undefined symbol: hb_icu_script_to_script“).
    • Solution: Downgrading to the original Slackware harfbuzz package solves it, which is a pity because I thought I had taken care of the ABI breakage by applying a patch which re-adds that missing symbol.
  • The hardware keys for altering volume and mute still do not work on a global level (at least on my Lenovo T400 laptop). They seem to work for some applications – VLC is one of them. Sound is working fine though.
    • Solution: How dumb of me… just run “kmix” and a systray icon will appear, and the support for on-screen display of your hardware volume buttons will be enabled.
  • KRunner (Alt-F2) will still not save your command history.
  • When you try SDDM in runlevel 4 and the screen stays black with a blinking cursor in the upper left, this is probably caused by a missing homedirectory for the “sddm” user.
    • Solution: Check the output of command, it should return “/var/lib/sddm” and that directory must exist and be owned by the “sddm” user:

      $ getent passwd sddm | awk -F ‘:’ ‘{print $6}’

  • Even though you’ve selected “Plasma” as your desktop in the SDDM dropdown or in “xwmconfig”, the KDE 4 desktop is still starting up instead of the Plasma 5 desktop.
    • Solution: Remove the kde-workspace package and re-install the plasma-workspace package.
  • I have installed slackpkg+ and configured it as instructed. After installing KDE 5, when I run “slackpkg upgrade-all” it tries to pull in or upgrade all sorts of original Slackware packages. What’s up?
    • Solution: none yet… you’ll have to be careful for a while until I figure out what to do with all those packages.
  • The shutdown and reboot options are missing from the Leave menu.
    • Solution: a simple patch which removes the use of “kwrapper5” to start the KDE services will bring back both options. Kwrapper is meant to speed up the start of the Desktop Workspace and be a bit friendlier on resource usage but if you really do need shutdown and reboot options present, then apply the following patch to “/usr/bin/startkde”:

Thinking about working on KDE 5 again (frameworks, plasma, applications)

qt-kde-620x350During these final days of my relatively long Christmas holiday, I have started looking at the KDE 5 build scripts again. KDE 4 has seen its final release sometime ago, and Patrick shows no signs of updating the KDE in slackware-current, so in order to bring some fresh excitement to KDE users on Slackware, I am pondering an update of the “testing” repository aka the KDE5 repository.

In December, the KDE community released the first tarballs of the “Applications” which is the first step to completion of the new KDE 5 desktop. Remember: the Frameworks 5 came first (a set of modular libraries that expand the functionality of Qt5), Plasma 5 builds a desktop workspace on top of the Frameworks, so that had to come next, and finally there are the Applications which are now ported from the KDE 4 Development Platform to Frameworks 5 slowly.

In particular that recent release of Applications 14.12 (the notation used here is gave me some headaches. Most of these applications are familiar from KDE 4, and only a few are now ready for the Plasma 5 desktop workspace (Kate and KWrite, Konsole, Gwenview, KAlgebra, Kanagram, KHangman, Kig, Parley, KApptemplate and Okteta). It is impossible for me to separate the KDE 5 applications from the KDE 4 applications. Their names have not changed, and whereas I needed to rename a few packages in Frameworks and Plasma in order to prevent a clash with package names in the KDE 4 set, I do not want to do the same for the Applications. After all, when running Plasma 5 you do not want to see both KDE 4 and Plasma 5 versions of the Konsole application in your desktop menu – just the Plasma 5 version. Also, compiling these “Applications 14.12” will cause a lot of KDE 4 packages to be overwritten – for example, marble-4.14.3 with marble-14.12.0 et cetera. That is a one-way road. I can not think of a clean method of separating the old and the new.

In my “preview” of KDE 5, I was able to offer the KDE 5 packages as co-installable to KDE 4 because it was not yet more than Frameworks and Plasma packages – it needed the presence of KDE 4.x in order to provide a meaningfull Plasma 5 workspace. That meant, you could install KDE 5, play around with it for a bit, and then un-install the packages if you had seen enough, without this process touching or destroying the configuration of your KDE 4 environment. That was a good thing, because Plasma 5 was quite unstable at that time, and the whole exercise was not meant to probide an actual day-to-day work environment.

We are now 5 months further in time, and the current state of Frameworks/Plasma 5 combined with the new set of Application releases, should provide a stable platform that is slowly migrating from KDE 4 to 5.

That is why I decided to not stretch my luck and try another co-installable version of KDE 5 but instead go all the way and provide a full upgrade from KDE 4.14.3 to Frameworks/Plasma/Applications. It will take a while because of all the unknowns, but I think I have done most of the preparations now (gathering all the sources, updating the build scripts). It will be a matter of compiling, fixing failures and retracing issues to their resolution.

I think I will also provide scripts for an easy roll-back from the new KDE 5 packages to either the default Slackware packages or else my KDE 4.14.3 packages.

Note that this is going to be relevant and beneficial only to people who are running Slackware-current (our development version) so if you are going to want to try this later on, you need to know what you are up to. Once you will upgrade from KDE 4 to my new KDE 5 packages, it may not be trivial (i.e. without cleaning out your ~/.kde and ~/.local directories) to downgrade at a later point in time.

End transmission.
