plasma search in application launcher?


using recent KDE neon (18.04), I see two different "search" approaches
on the desktop:

There's the "plasma search" (triggered by alt+tab on my device) that
searches across a wide range of sources, including packages and running

And there's the "search" in the stock "application launcher" (start
symbol in the task bar) which apparently just searches applications

Is there any way to make the "search" in the "application launcher"
behave like the "plasma search"?

Thanks in advance,

Start menu and "running" application instances?


coming from GNOME and playing with KDE neon, I feel mostly home here
right now except for one thing I didn't manage to set up myself: Is
there a way to, in the applications start menu when searching for
Firefox or Konsole, not start a new instance / window of the application
but rather bring a running instance (if there is one) to front?

Thanks in advance and all the best,

disable akonadi


my favoured GUI is KDE. But since KMail et. al. is such a PITA I don't
use applikation which needs akonadi anymore.

How can I disable akonadi so that there is no restart at each new login?


akonadi / kmail / gmail

Recent versions of kmail / akonadi plays so badly with gmail that it is
extremely irritating and the practical solution for me is restarting akonadi
many times a day using akonadictl restart

This is really annoying not least because spams my desktop three times with
the following unwelcome message,

"We're sorry, No such method 'agentName' in Interface
'org.freeedesktop.Akonadi.AgentManager' at objewct path..."

and only after this message is dismissed three times I get any progress.

Unless someone knows a magic cure for this problem, and it has been
extensively reported in the akonadi

Search window location in new Konsole


since recently, konsole has moved the window to input search patterns from a bar at the bottom to a small window at the upper right. I find this very unpleasant from a usability point of view. Usually you are focused on the very bottom left of the terminal window, where the cursor is. Now, if you use the search, you have to shift your focus all the way up and right to the search bar.

Is there a way to move the search window somewhere else or retain the old behavior?


input devices mouse setting no longer being used.

I have plasma 5.13.2 on Fedora 28.

One of the recent updates broke honoring the mouse settings.
I use left-handed and reversed scroll settings.

Now when I log in I get right-handed and non-reversed scrolling.

If I use the control panel to

1. change from left to right
2. apply
3. change from right to left

Then I have left-handed and the reversed scrolling.

Is this a known problem?

black screen and cursor, and nothing more


i'm making an attempt to switch from trinity desktop environment to
whatever version of plasma is installed when one installs kubuntu-desktop
in ubuntu 16.04. window manager is kwin.

when i select plasma at the login screen, all seems to go well but for the
appearance not of plasma but of a black screen with a mouse cursor. no
clicking of either button produces anything, and the only escape is
ant-f1, login, and rebooting from there.

i'd guess it's a tiny configuration issue, but i have no idea what it is.

Global menu in GTK applications does not work

Hi guys. I'm having a rather curious problem with KDE Neon that does not
happen to me in ArchLinux, for example. Applications like Firefox,
Thunderbird or LibreOffice show me the global menu, however, others like
GIMP or Inkscape do not. But, if I run GIMP or Inkscape in the terminal,
if they show the global menu ..

If I put the file .profile, .bash or .zshrc the command: export
GTK_MODULES = "appmenu-gtk-module" the variable is exported without
problems, but for more than restart, the same thing keeps happening to me.

Any idea what is happening?



Waste of screen space

Hello list,

Since the most recent upgrade of kde-frameworks on this Gentoo box, I get
huge icons in the Details lists of Dolphin and Konqueror-as-file-manager.
Example attached.

Is there any way to restore the icons to single-line height?

KDE 5 Plasma

Hello All,

I am unable to access https websites with KDE 5 Plasma. I know it's a

Trouble with Desktop-Icons


I have peeving trouble with my Desktop-Icons. Every now and then the order after a login
is lost and the Icons are unsortet on the Desktop.

I use openSUSE Leap 42.3 Plasma and the Oxygen Theme. This is not acceptable
and scares every new user who uses KDE on Linux.

To reconstruct the icons I copy a saved version from .config/plasma-org.kde.plasma.desktop-appletsrc
and login again. But this does not fix the problem until the next login.

What can be done to fix this and whar other files are involved to store the order of this icons?

This is all very annyoing!

Kind regards


how to debug kscreen?

When filing bugs related to kscreen, we are told to add information
according to this guide:
<a href="" title=""></a>

It starts with this instruction:

Create a script with the following content:

export QT_MESSAGE_PATTERN="[%{time hh::mm:s.zzz}] %{function}: %{message}"

It also includes editing ~/.config/QtProject/qtlogging.ini

So far, those steps are clear to me.

quotation character in kmail

after consulting the kmail in my desktop machine i found where the quote character can be set, on the composing > templates page in the extrme southeastern corner. didn't see it at first because the scrollbars are not easy to discern at a glance. wish there were an easy way to make the slider a contrasting color from the scrollbar itself. but, anyway, it's solved.

Color configuration issue on Plasma

Greetings . . .

I've installed and configured Ubuntu-18.04 with the Plasma desktop on a GPD Pocket computer, and the combination is remarkably nice and very useful.

In the course of configuring it I've been able to set colors, typefaces and font sizes, and so on almost entirely to my liking. The "almost" is because no matter what I do, I can't change the color of the windows' titlebar. I've told it to be white text on a black background (System Settings > Colors > Breeze High Contrast > Edit Scheme > Active Titlebar, then saved under a new name and chosen as the scheme to use).

plasma5 screen management going wrong

With the most recent update of KDE, screen management is acting up. I have
a desktop with 3 monitors. After this update, every time I log into
Plasma5, several things happen:

1. I get a popup asking me about laptop display options. This is not a
laptop. Furthermore, the options presented are confusing. None of them look
viable. I have been leaving it unchanged. However, I do not want this
dialog every time I log in when my attached screens have not changed.

2. The arrangement of my screens has changed (e.g., the screen that should
be in the middle is arranged on the left or right, etc.)


Update of 'menu' broke the menu and my Plasma 5.13 on Neon desktop


There was one single update today to menu:amd64 (2.1.47ubuntu1,
2.1.47ubuntu1.16.04.1) on my KDE Neon User Edition with Plasma 5.13 laptop.
After that I can not use many menu items and not open many package. The
desktop simply crashes leaving a black screen and then back to the login

Dolphin loses UI settings when restarted


whenever I launch dolphin 18.04.2, it loses some UI settings. It is especially weird, because when I start dolphin from scratch, i.e. `rm .config/dolphinrc && rm -rf .local/share/dolphin && dolphin`, it looks fine, e.g. <a href="" title=""></a>

Then I change nothing, just quit and start it again, it looks like <a href="" title=""></a>

Now I activate menu bar (Ctrl-M), sidebar (F9) and toolbar (using mouse), change view mode to detailed, and change the icon size.

Dolphin: add item to the context menu


in Dolphin it is possible to open a context menu at a file. (point to a
file and click the secondary button of you pointing device)

Dependend of the file type you get a few action options. (e.g. Burn the
file with k3b if the file is an ISO)

I want to add an entry to this context menu to get the checksum of the
file. Is anybody here who can lead me thougth this process?

Is there a way to force the use of a specific BT profile on a specific hardware/device?

I am using Leap 15 with KDE 5.12.5, Frameworks 5.45.0 and QT 5.9.4.

BT fails with me since years to pair correctly with BT audio devices provided
they have also a phone hands free function.
In this case, even selecting manually in the settings the right protocol
(A2DP), since the system perceives the microphone, it always starts the device
with HFP.

Since I do not use handsfree on my notebook, is there a way to force(!) the
A2DP protocol on the headset and on the BT box? Maybe with a "read only"
association of the profile for that given hardware?

Lost behavior between KDE and 5.5.5

I don't upgrade till a version is out of support since upgrades never work
and I have to do a wipe and load and that's an insane amount of work for
me. I've been using Kbuntu LTS 14.04 and loving it with KDE for
years now. I am in the process of taking several older computers that were
given to me and putting Linux on them as well as installing Linux for a
couple relatives and friends. I grabbed Kbuntu LTS 16.04 and slapped it on
the first machine. Ugg what a mess.

The install went quite smoothly on an old Emachine. It has 2 gigs of RAM
but KInfo only showing 1.5.

Konqueror 5.0.97 issues

KMail filter agent: get progress information from external filters?


Does the Akonadi mail filter agent provide hooks to inform it (and thus the user) about filtering progress when using an external utility (say a spam reporting tool)?


reposition window partly outside screen (kwin related)

I want my application to show the Qt virtual keyboard when it's running on a touchscreen.
To avoid that the virtual keyboard covers the input field, I'd like to move the whole
application window upwards so that the input field is always visible above the VKB, and move the window
back downwards when the keyboard hides.

However kwin seems to restrict the y-coordinate to only positive values.
Using xfwm4 this is possible (except when the window is fullscreen or maximized).

How can this be solved (best in a way which works regardless of the window manager) ?

Kopete 18.04 lacks of notification settings

It may sounds like a silly question, but can someone confirm there's no
Notification by default on the last version of Kopete?

I'm using it on Kubuntu with staging repos enabled, version 1.13.0
(4:18.04.1-0ubuntu1~ubuntu18.04~ppa1), which relies on Qt5. So, going into
Settings menù, "configure notifications" (translated from italian), nothing
shows up there. I've checked the previous version (which relies on Qt4) and
that panel is full of entries.

I don't know if it's a bug, or the devs are still porting everything out on

How to use the "opengl" qt rendering backend instead of "raster"?


I am using KDE on an AMD Kaveri based system featuring a 4k display.
Quite a few operations/animations feel rather slow on that machine
(e.g. the semi-transparent selection window on the plasma desktop, or
the slide-animation in kicker).
So animations inside windows (drawn by QT) are slow, the compositor
related animations are fluent and fine.

Looking at the profiles it all boils down to QT using the "raster"
backend. I see tons of cycles spent inside functions like
qt_memfill32, comp_func_solid_SourceOver_sse2 and the likes.

krdc blue screen ?


I am trying to use VNC via KRDC/KRFB to establish a remote desktop session.

Dolphin has become slow recently. In particular, adding or moving a

Previously, there was no noticeable delay.

manually reload Dolphin session?

Is there a way to manually open (reload) a prior Dolphin session?

I'm running KDE on Arch. Here's some system info:

- dolphin --version: dolphin 18.04.0
- Linux 4.16.6-1-ARCH #1 SMP PREEMPT Mon Apr 30 12:30:03 UTC 2018 x86_64

I often keep a lot of tabs open in Dolphin and I would like to be able to
open all those tabs / locations again. I have seen an old feature request
for Dolphin saved sessions. I'm not asking for that. I just want to know if
I can do it manually.

location of panel configuration file (lost my settings)

unlocked the screen saver, and when my desktop appeared, my panel was gone.
I had done a lot of customizations to my panel. I'd like to restore those
from a backup.

VPN kill switch

Hi all,

So within "Connections" in the system settings I've enabled an OpenVPN connection when my wired interface goes online, as well as with my home Wi-Fi SSID and so on. Is it possible to do the following?

1 - Enable VPN with all connections, no matter what. I connect to a new SSID in a cafe and the VPN link should go up.
2 - If, for any reason, the VPN goes down all outgoing connections are automatically dropped/rejected/whatever. That is, I would like to connect to the Internet only if connected to the VPN (only OpenVPN packets should go out if still not connected to the VPN).

Top of windows too tall and apparently non-adjustable in kde 5.

Hello everyone:

I've been struggling to configure the look of window decorations, specifically
the top, on Debian 9/Kde 5.28.0 (current stable) the way I had them on Debian
7/Kde 4.8.4. Unfortunately Kde 5 is so different that I can't figure out what
combination of theme, style, color, etc... I need to match what I had.

Specifically, I would like the height of the frame at the top of the windows
to be less tall, but I can't find any way to do this. I can also not get the
font size to change.

Kmail message storage folders

I currently have Kmail on my server, with thousands of messages in Maildir
format on a separate partition (which simplifies migration/upgrading).
They're sorted into many subfolders such as 'cars', 'accounts', 'kde' etc.

I typically ssh into the server from whichever laptop I'm using and run Kmail
on the server via ssh, which avoids any syncing issues.

Migration of kwallet failed


I did an upgrade of ubuntu 14.04 to 16.04 and now my kwallet is empty.

The version on the new system is 4:15.12.3-0ubuntu1.

The new kwalletmanager just says: "Error -9".

Now I installed an other machine with the old ubuntu 14.04 to open the

also fails with "Error 42".

Any idea how I can retrieve my passwords? It really would be urgent.

KDE apps not using system printer settings

Starting several months ago, all KDE apps (e.g., Kate) no longer use the
system printer settings. For example, in "Kickoff -> Computer -> System
Settings -> Printer Configuration" I have US letter paper size set.
However, Kate and other KDE apps all default to A4 paper size. I can't find
a way to change this default, so I have to manually change paper size every
single time I need to print.

I'm running Arch Linux on several different computers (NUC, laptop, desktop
and more). The problem appears on all systems.

KDE4 - Task Manager - not showing launcher icon?


We are using KDE 4.10.4.

I have one question about the Task Manager widget (X-KDE-PluginInfo-Name=org.kde.plasma.taskmanager).

When I add the Task manager widget to my panel, any applications I run(actually our own application) will not show the application's icon we specified in its .desktop file.

Instead, it will just display the same system icon (X with a circle)..

I already checked all below:

--Make sure the name of the .desktop file matches what the application sets as WM_CLASS window.

--Make sure that what's set as WM_CLASS makes sense and isn't something generic (e.g.

In this version of korganizer (kdepim), it seems the configuration to

The instructions I found for

Unable to resize some Gtk applications

I am unable to resize windows of some Gtk (or Gnome) applications.
Nothing happens when I place the mouse on the edge of window. No resize

The windows where this happens do not seem to have standard window
decorations. They do have min/max/close buttons, but that's it. I
believe this has something to do with "client-side decorations."

How do I fix this?

Disable popup when changing volume or keyboard layout?

Hi list,

is there a way to disable said info popups? For the layout there is the
indicator in the panel. Vor the volume, well, I can use the volume icon as a
guess-o-meter. I would like to do away with them but haven’t found out

Can you give me a hint? I’d be much obliged.

My rationale:
The poppus flicker over a video player and take ages to fade out (if I have
effects enabled). Also, they steal the keyboard focus. When I rename a file
and notice I need some typographical specialties, I would like to switch
from the programmer-friendly US layout to my native German.

Put all KDE config files under one directory like ~/.config/kde/

I found KDE put all components config files under ~/.config/.
Because there are lot of configs of KDE, and lot of programs configs
under it.
When I want to do something (like reset KDE configs) I don't know which
ones need to delete.
Put all KDE related config files under ~/.config/kde/ will help user.

Really. That's a totally mess!!!

KDE doesn't start after upgrade to Fedora 27

I have two systems that were recently upgraded from Fedora 26 to 27
using DNF system-upgrade. Both were successfully running a KDE desktop
for several generations previously, including on F26. In both cases,
after the upgrade, starting KDE showed the splash screen and then
a blank screen with only a pointer cursor. The keyboard and mouse
worked but the screen remained blank. Both systems are set to start
in systemd's multi-user mode; KDE is started with the startx command.

One of the systems is a 32-bit laptop with little local content.
