I am trying to take a high-resolution screenshot of an app. I want the screenshot to have more detail than what my display supports but I can't seem to find a seamless and easy way to do that. What I Have Tried: 1. KDE Built-In Scaling: This works well for taking higher resolution screenshots, but isn't really seamless as it increases the size of the window and I have to set it back to the default once I have taken the screenshot. 2. Using gamescope: I tried using gamescope to run KDE at a higher resolution and scale it down but couldn't get it to work as it always resulted in a black screen.

I'm following the tutorial: A full Python + Kirigami application to learn how to build Python applications using PySide6 and Kirigami for KDE, under Arch Linux and Fedora. However, when running the script, I get the following error:

        }
    }
}
I run it with: python3 src/__main__.py And I get this output:

./src/qml/main.qml:4:1: module "org.kde.kirigami" is not installed ./src/qml/main.qml: module "org.kde.desktop" is not installed My problem: I can’t figure out how to fix the error: module "org.kde.kirigami" and "org.kde.desktop" is not installed But Kirigami is already installed on my system.

I'm trying to connect to use remote servers in multi monitor setup with following command

xfreerdp3 /d:foobar.intranet /u:myuser /v:xx.xx.xx.31 \
    +clipboard +sound -wallpaper /cert:ignore \
    /multimon:force /monitors:0,3

The problem is that both monitors are mirrored in full screen and are not interactable (it's like they show a default desktop without any input). My monitors are:

❯ xfreerdp3 /list:monitor
      *  2560x1440	+2560+0
         1920x1080	+7680+0
         2560x1440	+5120+0
         2560x1440	+0+0

The thing which makes no sense to me is that in the window preview both monitors are rendered correctly but if opened it's still frozen. I'm using CachyOS with KDE Plasma, both on the newest default release.

I'm using Subversion on Linux with a repository hosted on a remote server (via https) and with kwallet as the password store. Everything works as expected except that each time I'm using something like svn commit or svn update from the KDE console, I get the warning

kf.windowsystem: Cannot use KWindowSystem without a QGuiApplication

although the command is still executed. I have added code to my ~/.bashrc to suppress this particular message, but I'd still like to know what's going wrong here. In case it matters: I'm using OpenSUSE Tumbleweed installed from snapshot 20250728 this week.

Officially, upgrading the KDE version of Linux Mint 17.3 to 18 is not supported , because "Linux Mint 18 KDE will use a new and different desktop called Plasma". I presume this means that the KDE4 to KDE5 upgrade process is not trivial. The official way to upgrade is to do a clean reinstall. I use Linux Mint on my main (scientific computing) workstation, and would much rather not do a clean reinstall: following advice, my /home/ is not on a separate partition, I have several different (non-physical!) users installed, and the official installers just want to wipe everything and start again. I'd really much rather not. What I'd like to do is update all of the apt sources to point at the right place, do an apt-get update && apt-get dist-upgrade and go home for the evening. As it stands at the moment, quite a few things randomly break every time I do an apt-get update (at the last one, nvidia drivers, cuda, and xfce due to a change in dbus!). I _like_ the look of Plasma, and the live usb of 18.2 runs great on my computer. I _want to upgrade_ *without* wiping _everything_. This is far from an unreasonable request. I have't heard of anyone else doing this _successfully_ for KDE Mint 17.3, and I'd like to know if it's possible. mintupgrade certainly thinks not. I'd like to try. What happens if you just do something stupid, like sed -i 's/trusty/rosa/' /etc/apt/sources.list?

Now I'm using KDE plasma as my DE, and I really like the style of elementaryOS. So I use a theme inspired by elementaryOS. But in some gtk apps, it has black border and some circle buttons are out of shape. btw, not only elementaryOS theme, but also some other theme have this problem. So what could I do to remove this annoying black border.

In Debian 11 stable with KDE, why would uninstalling konqueror also remove libreoffice, xorg,etc? Why would it cause the installation of firefox-esr? sudo apt-get remove konqueror Reading package lists... Done Building dependency tree... Done Reading state information... Done The following packages were automatically installed and are no longer required: apper apper-data coinor-libcbc3 coinor-libcgl1 coinor-libclp1 coinor-libcoinmp1v5 coinor-libcoinutils3v5 coinor-libosi1v5 cups-pk-helper fonts-symbola gir1.2-wnck-3.0 kdeaccessibility kmag kmousetool kmouth kontrast libkf5konq6 libqaccessibilityclient-qt5-0 libreoffice-calc libreoffice-draw libreoffice-help-common libreoffice-help-en-us libreoffice-impress libreoffice-kf5 libreoffice-plasma libreoffice-qt5 libwnck-3-0 libwnck-3-common lp-solve mythes-en-us node-normalize.css orca print-manager python3-brlapi python3-cupshelpers python3-louis python3-smbc python3-speechd qtgstreamer-plugins-qt5 system-config-printer-common system-config-printer-udev task-desktop x11-apps x11-session-utils xbrlapi xinit xkbset xorg Use 'sudo apt autoremove' to remove them.

Need to get 55.5 MB of archives. After this operation, 180 MB of additional disk space will be used. When I sudo apt autoremove, it doesn't try to remove those "no longer needed" packages. But when I try to remove konqueror, it says it will remove a whole lot of stuff that seems completely unrelated.

I run latest OpenSUSE tumbleweed, KDE only. I wish to switch the default session from Plasma X11 to Plasma wayland. What should I do to achieve this? The login manager I use comes from sddm. And I can indeed manually log in from the login manager to a wayland session.

Why do I get this in the console when restarting plasmashell with killall plasmashell and kstart5 plasmashell in Debian11/KDE with Wayland and how to solve the problem? Of PipeWire I currently only have libpipewire-0.3-0 installed, I searched for screencast in Apper but don't have anything of that installed. I'm using PulseAudio and I think I also got this error when I ran something else than plasmashell but it's probably the same cause. I'm not screenrecording but have some apps that can do so. I tried uninstalling xdg-desktop-portal and this reduced these errors but the error still shows, it went from 8 times the above error to only one:

error creating screencast "Failed to connect PipeWire context"
trying to show an empty dialog
DataControlOffer: timeout reading from pipe
DataControlOffer: timeout reading from pipe
DataControlOffer: timeout reading from pipe
DataControlOffer: timeout reading from pipe

**Edit**: it's two errors now and unlike before these only occur after waiting for approximately 20 second after starting plasmashell (the other errors are because of kdeconnect trying to start without being configured to so which I blocked and asked about separately):

...
error activating kdeconnectd: QDBusError("org.freedesktop.DBus.Error.Spawn.ExecFailed", "Failed to execute program org.kde.kdeconnect: Permission denied")
kdeconnect.interfaces: dbus interface not valid
kdeconnect.interfaces: dbus interface not valid
error creating screencast "Failed to connect PipeWire context"
error creating screencast "Failed to connect PipeWire context"
libpng warning: iCCP: known incorrect sRGB profile

**Edit 2**: this error does not occur on another machine with nearly the same setup. Plasmashell is version 5.20.5 in Debian11. The same error occurs again when waiting for a while. How can I find out the source or traceback of this error message (may be a separate question)? I'd like to find out what software causes it, it's probably something that plasmashell launches. **Edit 3**: after upgrading to **Debian12** and resuming from sleep these lines show in journalctl shortly after resuming. Why and what should I do:

systemd: NetworkManager-dispatcher.service: Deactivated successfully.
kwin_wayland_wrapper: kwin_screencast: Failed to connect PipeWire context
kwin_wayland_wrapper: kwin_screencast: Failed to connect PipeWire context
plasmashell: error creating screencast "Failed to connect PipeWire context"
...

Is there some problem with kwin_wayland or a pipewire package missing? It seems like many people get these messages so some further information would be useful.

I am trying to configure dual-seat on my Linux with KDE-Wayland. I have two graphic cards which should make it possible. I configured an /etc/udev/rules.d/72-multiseat.rules

# Assign second graphics card to seat1
SUBSYSTEM=="drm", KERNEL=="card1", TAG+="seat", ENV{ID_SEAT}="seat1"

# Assign Logitech K120 keyboard to seat1
SUBSYSTEM=="input", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c31c", TAG+="seat", ENV{ID_SEAT}="seat1"

# Assign Logitech Logi Bolt Receiver (mouse) to seat1
SUBSYSTEM=="input", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c548", TAG+="seat", ENV{ID_SEAT}="seat1"

Then applying the configuration: sudo udevadm control --reload-rules sudo udevadm trigger Unfortunately, after this login into KDE is not possible anymore, for either seat. ----------------- How to configure multi-seat (several users at the same time) on Linux with KDE-wayland?

i installed KDE on Arch Linux and am using the Breeze theme, although no matter what theme or set of icons I choose, icons do not show up in my terminal or file manager, which i believe are from pantheon. here is an image: Icons show up just fine in oher applications like Firefox and the settings program for KDE Plasma.

I wonder how to start the KDE Desktop via X11 on my CentOS 7. So I installed: yum groupinstall "KDE Plasma Workspaces" -y and set: systemctl set-default graphical.target I am using putty from a Windows 10 client with working ssh login and I set the "Enable X11 forwarding". I also installed Xming and tried xclock& and xeyes& in my terminal. Both are working like a charm.

I would like to insert the current date into an open Kate text document while editing it by using a shortcut key combination. I see several such options for Atom, but I don't find anything for Kate.

So I installed a VNC server (Tight VNC) on my workstation 'orac' which is running Debian Jessie with KDE Plasma. And a VNC client (also Tight VNC) on my workstation 'tact' running Debian Stretch with KDE Plasma. I ran vncpasswd on orac to configure the password. I want to use VNC to use 'orac' from 'tact'. From tact I ssh'ed to orac and started the vncserver: jj5@orac:~$ vncserver New 'X' desktop is orac:1 Starting applications specified in /home/jj5/.vnc/xstartup Log file is /home/jj5/.vnc/orac:1.log Then from a console on tact I ran: jj5@tact:~$ vncviewer orac:1 Connected to RFB server, using protocol version 3.8 Enabling TightVNC protocol extensions Performing standard VNC authentication Password: Authentication successful Desktop name "jj5's X desktop (orac:1)" VNC server default format: 32 bits per pixel.

Least significant byte first in each pixel. True colour: max red 255 green 255 blue 255, shift red 16 green 8 blue 0 vncviewer: VNC server closed connection Before vncviewer: VNC server closed connection is reported everything seems to be working smoothly. A window opens, I see KDE Plasma doing it's login/loading thing, then my orac desktop loads, a bunch of default Dolphin windows load, and KDE Plasma starts processing my autostart scripts, so everything seems to be working fine, and then almost as soon as it starts KDE/VNC disappears and shuts down usually with vncviewer: VNC server closed connection but sometimes with vncviewer: read: Connection reset by peer instead. So why is KDE (or VNC?) bailing just as soon as it starts? Any help greatly appreciated! p.s. here's some extra info about the environment on the VNC server (orac): jj5@orac:~/.vnc$ ls -al total 24K drwx------ 2 jj5 jj5 4.0K May 4 17:35 ./ drwxr-xr-x 74 jj5 jj5 4.0K May 4 17:35 ../ -rw-r--r-- 1 jj5 jj5 1.3K May 4 17:36 orac:1.log -rw-r--r-- 1 jj5 jj5 5 May 4 17:35 orac:1.pid -rw------- 1 jj5 jj5 8 May 4 15:52 passwd -rwxr-xr-x 1 jj5 jj5 263 May 4 17:32 xstartup* And the log file says: jj5@orac:~/.vnc$ cat orac\:1.log 04/05/17 17:35:57 Xvnc version TightVNC-1.3.9 04/05/17 17:35:57 Copyright (C) 2000-2007 TightVNC Group 04/05/17 17:35:57 Copyright (C) 1999 AT&T Laboratories Cambridge 04/05/17 17:35:57 All Rights Reserved. 04/05/17 17:35:57 See http://www.tightvnc.com/ for information on TightVNC 04/05/17 17:35:57 Desktop name 'X' (orac:1) 04/05/17 17:35:57 Protocol versions supported: 3.3, 3.7, 3.8, 3.7t, 3.8t 04/05/17 17:35:57 Listening for VNC connections on TCP port 5901 04/05/17 17:36:04 Got connection from client 10.1.1.126 04/05/17 17:36:04 Using protocol version 3.8 04/05/17 17:36:04 Enabling TightVNC protocol extensions 04/05/17 17:36:06 Full-control authentication passed by 10.1.1.126 04/05/17 17:36:06 Pixel format for client 10.1.1.126: 04/05/17 17:36:06 32 bpp, depth 24, little endian 04/05/17 17:36:06 true colour: max r 255 g 255 b 255, shift r 16 g 8 b 0 04/05/17 17:36:06 no translation needed 04/05/17 17:36:06 Using tight encoding for client 10.1.1.126 04/05/17 17:36:06 Using compression level 1 for client 10.1.1.126 04/05/17 17:36:06 Using image quality level 6 for client 10.1.1.126 04/05/17 17:36:06 Enabling X-style cursor updates for client 10.1.1.126 04/05/17 17:36:06 Enabling cursor position updates for client 10.1.1.126 04/05/17 17:36:06 Enabling LastRect protocol extension for client 10.1.1.126 Note that 10.1.1.126 is my VNC client 'tact'.

I installed Manjaro with KDE and set up the Telegram desktop app. Persian (Farsi) text in Telegram displays in a very unattractive font. Is there any way to change the font family?

I wrote the following .desktop file for my application named Qtag: [Desktop entry] Name=Qtag Comment=Audio tag editor Exec=qtag Icon=/usr/share/pixmaps/Qtag.png Terminal=false Categories=Multimedia; Version=1.0 Type=Application I copied it to /usr/share/applications, but I still cannot find my app in the menu (I use KDE Plasma 5 application launcher). When I try to open the file in Dolphin (the KDE file manager), it says that there is no Type=... entry in the file. I use KDE Plasma 5. The executable and the icon are in the right places (qtag is in /usr/local/bin).

After updating to RHEL7 from RHEL6 my Konsole fonts are looking ugly and un-antialiased(Monospace size 11 in both systems). I played around with font antialiasing system settings but I am unable to make it identical to how it was before. Is there a way to restore the looks of font? i.e by copying some old font file or some settings from old system? Same issue is there for my Gvim.

I'm using KDE Plasma with KWin window manager on a dual-monitor setup. The monitors have different resolutions and sizes, which causes the mouse pointer often get "stuck" in the corner where the two screens meet and a lot of time i can't find my cursor (because it got stuck somewhere). **The Goal:** When I use Ctrl+Tab to switch between windows, I want the mouse pointer to automatically be at the top-left corner of the newly focused window's monitor — regardless of which screen the window is on. I often have to move the cursor manually across monitors, and the inconsistent layout makes it difficult. Ideally, I want this to be: Automatic (when a window is focused) Manually Toggleable (enable/disable this behavior) There is kwin script that doing this in x11 , but not wayland:

I'm using KDE Plasma with Dolphin on Debian 12 Bookworm, and I want to completely disable all tracking and history features related to: - Recent Files - Recent Folders - Clipboard History - Search History - Recently Used Applications I want also to clear any data and history that has already been collected by these features. How to prevent KDE from re enabling or recreating those logs. Im looking for a thorough and systemwide solution that ensures KDE does not track or show anything from past activity. What is the correct way to achieve this?

What is the problem and how to fix it? gdmap looks like this: I think it has to do with GTK. I'm using Debian 12 with KDE and Wayland. On a nearly identical machine gdmap looks fine. I have libgtk-3-0 and libgtk-4-1 installed and when I enter sudo apt-get install gdmap nothing is asked to be installed and I already tried reinstalling. Other apps like Firefox and Lutris look normal. It's not only gdmap but also other apps, namely VeraCrypt which I installed locally and GParted. The icons can't be seen. LibreOffice is also broken and looks like very old software.
