How to use VNC in KDE4?


We are using KDE 4.10.4.

I have Vino Server installed and configured to be auto started.

Then I tried to use remote-viewer to connect to remote KDE desktop, but
not sure how to configure it.

Any documentation?


error: ksysguardd - Internal buffer too small to read '/proc/cpuinfo'

How can I resolve this error I'm seeing in the logs?

ksysguardd - Internal buffer too small to read '/proc/cpuinfo'

cat /proc/cpuinfo lists 40 processors. The system has two Intel(R) Xeon(R)
CPU E5-2630 v4 @ 2.20GHz with 10 cores each.

fine vertical scrolling with keyboard

[kwin 5.8.7, up-to-date openSuSE Leap 42.3]


within an HTML browser I can easily scroll up and down with the arrow
keys which use, say, 100 pixels per keyboard press. Is there a way to
have, say, 'Alt + Arrow Key' to move 10 pixels instead? Ditto for
one-pixel moves?


Migration of kwallet failed


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

The version of kwalletmanager on the old system was 4:4.13.2.

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
kwallet there and export it to XML. But opening the kdewallet.kwl there
also fails with "Error 42".

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

Amarok + USB-Stick


it seems I do something wrong. I have an USB-Stick (USB-3; 132 GiByte)
this is connected to the USB-3 Port of my computer. All things are fine
(read, write) as long as I do not use Amarok.

I have copied ~25000 Files to the stick and build (just now) a playlist
(~130 titles).

kdialog: sound file from notifyrc file was not found,

I'm using a kdialog in a bash script. It gives the following output:

org.kde.knotifications: Audio notification requested, but sound file from
notifyrc file was not found, aborting audio notification

Where should the file notifyrc be and what is an example of its contents?

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.

KDE 4 - kdepim - korganizer - no google calendar?


I am using KDE 4.10.5 with kdepim-4.10.5-6.el7.x86_64, which contains

In this version of korganizer (kdepim), it seems the configuration to
include Google calendar does not exist.

The instructions I found for
configuring the tool indicate that you should click settings->Configure
KOrganizer->General and then click on the calendars tab.

From there, click the add button, select Google calendars and tasks
from the list.

I don’t have “Google calendars and tasks” in my version.

Can you confirm if that

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 - How to disable the Switch User and Lock in Leave Menu ?


I am using KDE 4.10.

I would like to find out how to disable the Switch User and Lock in
Leave Menu.

I don't want to disable Switch User and Lock button in the Leave Menu at
system level.

Instead, I would like to do it at user level.

Plasma needs a media player, I suggest Kodi

In the future, there will be more options for streaming, I'm talking
about paid services where content is streamed, like TV and on demand

Kodi is modular, advanced, and looks good. It's the first complete
media center I've used on x86 PC. There is a presence of pirates, but
that can be changed.

Disabling blue line under title bar?

In Plasma 5.12, there's a blue line under the title bar when the window
has focus. I searched for a setting to disable it, since it breaks the
"seamless" feeling of windows and looks quite ugly to me, but can't find
such setting.

Can I disable it?

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.

Running login/logout scripts in Plasma


I've configured "systemsettings5" to run a login and logout script. I was running perfectly until quite recently and now neither of them run.
I logged a bug against "systemsettings5" which i think is incorrect - can anyone point me to the correct module to log this bug against?



KDE 5 screen size issue


I recently upgraded my AWS Ubuntu system from v14.04 to v16.04. The
upgrade also updated my KDE from version 4.x (not sure of the exact
version) to version 5.18.0 . The problem that resulted is that the
screen geometry setting via xrandr is not being applied correctly.
I've attached a screen shot for clarity.

Notice how the bottom panel floats pretty high; and how the wallpaper
does not cover the entire screen, even though the setting is to scale.
I can make the screen size smaller but I still have problems.

Kwallet broken


I don't know, what has happened, but suddenly Kwallet is no longer available.
When I log in to plasma on my desktop, I get two windows, each asking me to
enter a password - one for KMail and one for the Nextcloud-desktop-client.
(I'm writing this on my laptop.)

There is this error message: "Couldn't open wallet:
org.freedesktop.DBus.Error.NoReply; Message recipient disconnected
disconnected from message bus without replying"

When I open the KWalletManager, the wallet is empty.

What happened, and how to fix this?

Qt 5.9 and font rendering


Did anyone notice any changes in font rendering quality after upgrading to Qt 5.9x?

I did, certain fonts (among which Novarese BQ) looked significantly "watered down", on systems that have Freetype 2.6.5 as well as one with Freetype 2.7.1 . Upon verification with Qt,

which probably explains what I'm seeing. I may however also be looking at an interaction with the Freetype Infinality and accompanying FontConfig patches.

baloo_file_extractor is slowing me down.


I am running KDE Neon user edition. Recently I have noticed that my laptop
has been slow and sluggish. I have found baloo_file_extractor to be the
culprit. After a while is consumes 4 GB or RAM and between 50 and 100% of
my CPU. As soon as I kill the process my laptop speeds up again. I'm not
sure exactly when this started but it has been during the last couple of
months. I have noticed I have a very large ~/.xsession-errors file with a
lot of baloo references in it.

KDE (or X?) clipboard goes stupid

[kf5 5.38, plasma-workspace-5.10.5, Fedora 25]

My KDE/X clipboard goes astray sometimes. I Copy URL to clipboard from KMail,
for example, and when I paste I get something from a day ago pasted.

Is there any way to reset that clipboard without restarting X or KDE? I'm not
talking about Klipper, but the default clipboard.

KWin render backend and window content


Does anyone on this list know answers to the following?

The "tearing prevention" option in KWin's Compositor setting has a large effect on video playback on my system. The only way I seem to be able to avoid tears and partial screen updates are

OpenGL + fullscreen repaints tearing prevention
XRender (+ Automatic tearing prevention)

I presume that "fullscreen repaints" corresponds to the good approach where you update an offscreen framebuffer and then swap that with the onscreen buffer just before the screen starts to repaint.

has knights been ported to plasma 5 or will it die?

I played chess today and noted it is still for SC4.
Has KDE Knights (the chess program been ported to plasma 5?
It would be a pity if not, I am not aware of a real native plasma 5 compatible

Thank you.

KDEconnect on 2 different networks: totally impossible?


I've been trying to get KDEconnect to work across a router and it
appears to be impossible. My internal network, where the linux KDE
is, is at 192.168.x.0, the android phone with KDEconnect is at
192.168.y.0. Traceroute reaches the phone so it's not a routing
problem. I have found this:

and it says (in the Configuring KDE Connect section):

Note: pairing WILL NOT WORK if your Android device isn’t on the same
network as your PC.

Dolphin: how to dereference soft links?

Hi there,

When using drag&drop to copy a softlink to another directory, a new link to
the original file is created. This is not always a useful behaviour, especially
when the target directory is for example an usb stick and the file should be
transferred to another computer who cannot dereference that list.

I did not find a way to do that in dolphin, so I had to do that in a terminal
via cp.

Is there a way to do that in dolphin?


Akregator Font Rendering Issue

Hello all,

I've been encountering a font rendering issue with Akregator (I'm running
Kubuntu 17) causing text within the content tab of the application to
render improperly. As you can see in my linked screenshot, the text in most
of the program renders properly, whereas that of the content block has some

Chrome/ium and KWallet


Here's something I've been annoyed by for a long time, I thought I'd check here if I'm right and maybe not alone in this:

Google Chrome has long had KWallet integration and has had a habit for a few year now to present the KWallet unlock dialog as soon as you load a page which has something that looks like an authentification feature.

I try to make my laptop screen display more than what his natural
definition allows.

pgp passphrase and kwallet?


I just almost had to replace a little-used pgp certificate because I couldn't remember the passphrase. Fortunately I had it stored in a keychain on my Mac.

I've looked but cannot seem to find an equivalent for KDE allowing to store certificate passphrases in a wallet. It's not in Kleopatra in any case.




I've been using krecipes quite a bit, even tried to contribute a converter feature, but it appears to be abandonware. Anyone on here familiar with the code, and potentially interested in porting it to KF5? Or maybe there's another comparable application out there which is maintained actively (and can hopefully import data from krecipes)?



kde font rendering for Chinese character is bad

I try kubuntu, and find kde font rendering for Chinese character is bad for both bitmap font and vector font.
gnome font rendering is ok for bitmap font, the same as kde for vector font.

Korganizer doesn't show CalDAV calendar. No errors, just no calendar.


I exported to vcs format from Korganizer 4.4.11 (that does not support
CalDAV) and placed the resulting file in a Radicale server. Then, set
up multiple versions of Korganizer (5.2.3 - 2 of them, 4.14.1) to access
the "DAV groupware resource". Entered the proper user, password, URL
(manual configuration) and when I was done all instances fetched the
collections and they now report "Ready".

I am working on specifying the latest software version of KDE applications

Tree View expand animation

How turn off tree view expand/collapse animations?

Can someone reproduce this kate/kwrite crash?

I'm getting a lots of crashes with Kate (and Kwrite). I was able to
reduce the offending text that causes the crash to this:

(*Without* the quotes.)

" ;"

That is, one or more spaces, followed by a semicolon. Can someone try
and reproduce this? To trigger it, create a new file:

kwrite test.txt

Then, in the menu select "Tools->Indentation->C Style". And then place
the text caret at the end of the line (right of the semicolon) and press
enter to insert a new line.

stealing focus ... back, with a shortcut key?


All of ye people who use a focus-follows-mouse mode probably know the situation where for instance you click on a link in an email, the webbrowser comes to the foreground and takes focus. With KWin, you can mouve the mouse cursor all you want, as long as it remains in the original (email) window you won't get your focus back.

Sometimes that's exactly what your want, preferably without having to touch the mouse. Older WMs (often?) had a "give focus to window under mouse" command which could be assigned a shortcut.

Kmail without kdewallet?

I'm running Kmail 5.2.3 and kdewallet under Debian 9. Can I safely uninstall
kdewallet? (Kmail is the only program I run that uses it).

Reason is, I usually start Kmail on my server via ssh from some laptop or
other. If I go to fetch mail from my ISP, Kmail opens a box for my ISP's
mail password (the same as my previous installation of Kmail 4 did).
However, IF I've previously logged in to my server, kdewallet opens a box for
its password on the server instead, which is a nuisance (and much bafflement
before I accidentally found this out).

Setting encoding in Kate

Is there a way to mark a file as using a specific encoding? Like some
string inside a C comment that Kate recognizes?

Change which PAM config file kcheckpass uses


By default on Debian-based systems, kcheckpass (used by kscreenlocker_greet)
uses /etc/pam.d/common-auth, but I would like to define a separate PAM
configuration for kcheckpass. Would I just need to create
/etc/pam.d/kcheckpass, or do something else?



start menu icon


In Plasma 5 we can right-click on the start menu and set our own icon.
However when I switch my menu from kicker to kickoff or kickerdash, the
menu icon changed to the default one and when I switch back to the kicker,
my own icon was gone and the default one is used. Would anyone please tell
me how to keep my own icon in the kicker mode, or even when switching to
different menu mode?


Configuring/compiling gbuffy on modern Debian systems.


Gbuffy was removed from Debian quite a few versions ago, not sure why but
I'm still using it on my Debian 7.11 system. To install it I had to manually
install gtk 1.2 and whatever other dependencies were needed, from ubuntu
packages IIRC.

This page explains the old dependencies.

Two-Factor Authentication on KDE Plasma 5 and kscreenlocker_greet


I am interested in configuring two-factor authentication on KDE Plasma 5 using a
PAM module for the second authentication factor (e.g. OTP) in addition to a
password. I have found that SDDM does not support this yet:
<a href="" title=""></a>

I could use LightDM or GDM instead of SDDM for the display manager, but the
screenlocker will also need to support two-factor authentication.

what does the drawing pin / thumbtack do?

Having a play with kde plasma 5. I have not used kde for about 10 years.
Much has changes in that time. I can't figure out what the purpose of the
drawing pin / thumb tack on the top left corner of a window. Somebody
please reveal it's purpose, or point me in the direction of an appropriate
web site.

How to backup file tags and comments?

Dear all!

I see that now in Plasma 5.10.2 at least for me the first time both file tags
and comments (that I can enter via Dolphin) seem to be stable and not suddenly
disappear. So I would like to use them much more, BUT...

... I would also like to know how I can backup the database(es) that this is
based upon so that in case of setting up a new / different KDE distro I can
"simply" restore all the meta file information.

Thank you very much in advance for helping!

border (or frame??) missing on Konsole


I am using KDE 4.4.14

I have my Scroll bar ... on the left side...

The right side has nothing so when I hover mouse
to let say stretch the window [horizontally] it's
visually difficult (for my old eyes) to spot the
border (which does not really exist)

how can I get the border enabled on Konsole?

thank you,

Task manager window grouping failures and KWin window-action slowness

I have LOTS of windows, and while task manager window grouping in KDE4
started off pretty bad early on, it got better for me.

In Debian Jessie, i would have issues running 3 different firefox
profiles with differing Class Instance names, where it would still
*usually* correctly separately group them, but sometimes draw the
incorrect icon for them.

Where are Kate syntax files stored?

Syntax highlighting XML files used to come with katepart, but that's
