I know both are different things, but I wanted to know if it makes any difference if I use KDE with GDM3 instead of SDDM. Can it affect the performance, because of the difference of auto-start processes, if any?
Or GNOME with SDDM?
Because I am thinking of using 2 DEs on Ubuntu 20.04. I am asking for if in case I happen to switch DEs due to some reason periodically.
So I have a specific task. I need to have an instance of a ubuntu variant (In this instance, kubuntu) running without a GUI so I can shell into it. However, I'd like to also render the desktop with XServer in its entirety without having a gui running on boot. The gui instance should be ONLY for the xserver client (or other client I don't know about)
Is there a solution to this? I can render a firefox window but that's basically it with my limited experience.
There's a bit of a catch-22 when trying to get multiseat working with kde plasma. kwin_wayland queries org.freedesktop.login1 to find out what seat it's on (ignoring XDG_SEAT), and (e)logind expects each program to notify it of which seat they want to use. The docs on freedesktop.org are less than helpful (haven't been updated since 2013 or so), suggesting you pass a -seat <seat> parameter to X when you launch it. Every other resource I could find said to just configure your display manager of choice accordingly, but they either would pull in lots of unwanted dependencies, don't properly support wayland, are buggy/unmaintained, or some combination of all 3.
Anyway, a deep dive into the source code of elogind, pam, su, login, and kwin_wayland later, I've got a solution: A general purpose script that can run an arbitrary program on an arbitrary seat, by asking PAM to initialize a virtual session attached to a seat.
You can get it here: https://github.com/perkinslr/multiseat_kde
I use openrc and elogind, so there's probably some tweaking to do to make it run under systemd-logind, and it required GCC and pam-dev available (or at least the security/pam_appl.h file).
Note that if you start seat1 while seat0 is still at the tty login, the keyboard (and mouse) input from seat1 will also go to seat0. I've not got a good solution for it, but I use autologin anyway.
Hey all,
Dunno if this has been overlooked or what but I noticed something interesting when messing around with the partition manager.
I'm in the middle of creating images and Clonezilla cannot clone from a larger drive to a smaller drive unless you shrink the partition first (and use -icds when applying the image).
Anyway, initially I had problems with getting the thing to boot. It would go to black after the KDE logo, turns out that I needed to change the UUID on the fstab. Once I did that it would boot into KDE fine.
However, when you go to expand the drive again you need to move the linuxswap to the end of the drive and extend the primary partition. This isn't a bit deal but when I rebooted it took a few minutes instead of a few seconds.
The issue is that the linuxswap UUID had changed because I moved it. I'm a complete noob to this so I wasn't expecting it, plus I don't see any mention of needing to update fstab when moving partitions in the KDE Partition Manager documentation
If moving a partition effects the fstab, which in turn effects the booting time of KDE shouldn't it be part of the docs? I've asked this before, but shouldn't there be some sort of check or warning given to the user for a broken fstab file? (e.g. your boot time took longer than usual, please run blkid -o list and check your fstab file for inconsistencies).
First time users to KDE would be impressed by a fast boot time, accidentally causing a slower boot time due to a broken fstab made by changes to the partition is kinda invisible and people are more likely to blame the OS rather than themselves. It would be great if there was a self-check of the fstab file to prevent the user from unwittingly causing this (or KDE Partition Manager prompting the user to update fstab with the new UUID after moving a partition).
What do you think, has anyone run into this or I'm I just an edge case?
EDIT (FIXED):
I wanted to execute "qdbus org.kde.lattedock /Latte activateLauncherMenu" at Meta key pressed. To do this, I had to remove the Alt+F1 shortcut for Application Launcher, via Shortcut settings.
Then I had to:
kwriteconfig5 --file kwinrc --group ModifierOnlyShortcuts --key Meta "
org.kde.lattedock,/Latte,,activateLauncherMenu"
and then:
qdbus org.kde.KWin /KWin reconfigure
I'm a long time Gnome user, since like v2.08. I've even come to like Gnome 3 despite it's sometimes overly simplistic madness.
One thing I absolutely love, is nautilus. It is absolutely the file manager of the gods imo. I forayed into KDE a bit a few months ago and was liking it until I opened up dolphin. It didn't seem to have the nice network integration nautilus has with network shares, it's ugly, and I don't recall what else, but I recall my abhorrent look of horror as I tried to use it.
What file manager to you KDE penguins use and love? Do any besides dolphin integrate/play nicely with KDE overall? Is using nautilus on KDE an option, with out breaking the look/feel?
Hey, kde newbie here. I've used gnome-session's ssh key agent and seahorse for over a decade---trying something new finally.
I just started using kde, and so far I dig it, I really do. Ubuntu studio switched and I thought I would give it a try.
Basically, I would like my ssh keys loaded when I log in. Does kde have a smooth way to do it. I notice others mentioning kwallet, but I don't see the whole picture I guess.
Thoughts?
Thanks!
Hello everybody,
I was using i3 WM for quite a while but the lack of grouping workspace (in a multi monitor setup) make me switch to KDE because of his Activities feature.
Basically it allows to switch workspaces (currently active as well as the one not active - not focused) on all the monitor at once.
While I gain this switching ability (called Activities in KDE) I lost the Tiling feature.
So I want to go back to a Tiling WM system, but I really want to be able to switch workspaces (on all the monitor at once) like how KDE Activities is doing that.
Does anyone know which Tiling WM offers this feature?
Thank you.
Hello, new openSUSE Tumbleweed user here, scratching my head why the KDE Plasma 'icons only taskmanager' does not work like it does in other KDE distros (coming from Fedora KDE Spin), also tested Kubuntu and KDE Neon to confirm this likely to be SUSE exclusive issue.
When in Wayland session, opening pinned app from icons only task manager only shows launch feedback for the first opened app. If a pinned app is already open, then next launched app won't show any launch feedback (taskbar spinner animation over the app icon), but the icon stays static until the app is completely launched.
Any body else experiencing this?
Just a simple question:
How do I export the Configuration of my KDE Desktop "Krohnkite".
I put an hour into configuring my KDE to work like a Tiling Window Manager (without loosing KDE and its benefits) with this tutorial (https://www.youtube.com/watch?v=n4pppzPxD3Q).
Are all of the changes which I made (exactly the same as in the video) saved in config files which can be exported easily?
I did a fresh install of Arch Linux+KDE and in my old version which was set up the exact same way I WAS able to pin flatpak VLC to the task manager (the bar at the bottom of your screen). I am not able to do that since doing a fresh install. When I right click the icon "Start new instance" and "Pin to task manager" are greyed out. I can only select More options or close.

Hi! Am looking for a window tiling manager appreciate the one in pop os, any suggestions?am a newbie :)
Hey all,
I noticed something while I was making OS images. The disk management tool in Windows allows you to shrink and expand the drive while working on that drive.
This isn't true of KDE Partition Manager where you have to boot into the LiveUSB in order to change the size of partitions.
I'm wondering is this a limitation of the filesystem itself or is it possible to resize while on a mounted disk in Linux?
Just curious as to why it works that way in Windows.
lightdm seems to have issues
more info: I upgraded from previous version
Hi,
I just updated from plasma 5.23.2 to plasma 5.23.3 and the everything seems to be zoomed in (Fonts, window decorations etc)
Before update : https://imgur.com/WSq6XOv
After update : https://imgur.com/i8ABAZv
Any idea why this is happening?
From the Majaro GUI, the refresh rate of the display can be set using System Settings>Display Configuration.
I'd like to set my refresh rate as part of a post installation script, how can this be set from the terminal?
So I'd like to try out rounded display corners (kinda like on macos) on kde (Arch linux, X11), but there seems to be no straightforward way (at least from my googling).
I have found this, but it only works on one monitor and I have not been able to compile the source code so far, so I could modify it to work on multiple screens.
In case someone was wondering what I want:
the leftmost screen has the rounded corners applied, but as I said, I can't do it on the others
I have a 120Hz monitor, but KDE doesn't remember that fact and on reboot sets it back to 60hz.
Very frustrating bug.
Hello all
I recently made the switch from Windows to Linux and copied all my data to my second 3 TB drive for transfer. I knew that NTFS and Linux don't like each other very much, so I made a backup of the drive before trying to use it on Linux.
Well, my prediction came true. The drive corrupted and the Filesystem isn't recognized anymore. However, when I try to restore the backup I made beforehand, I also get an error. But a weird one. After all the data has been written to the drive again, I get the following message:
Resizing file system from 1’903’617’376’256 to 7’814’033’408 sectors.
The file system on partition ‘/dev/sda1’ cannot be resized because there is no support for it.
Maximize file system on ‘/dev/sda1’ to fill the partition: Error
WARNING: Maximizing file system on target partition ‘/dev/sda1’ to the size of the partition failed.
This is weird to my because my drive only has 7'814'037'168 sectors to begin with, the partition was only half that size when I backed it up in the first place.
The Filesystem is unrecognizable again and even Windows detects it as a RAW drive. ntfsfix, chkdsk haven't been able to restore the partition. Testdisk worked to an extent but it tells my that the MBR is broken.
Is there a way for me to even repair the partition at this point?
Update1: Let me elaborate on "Testdisk worked to an extent". It was able to recover the MFT of the partition which should confirm that there is some data present, since it used the MFT Backup to do so. In Windows the partition is still recognized as a raw drive. I ran some data recovery tools on it and none found any data. One tool I downloaded allowed me to look at the partitions data in hex form to see what is left over. What I found was an MFT, and MFT Backup and a whole drive filled with zeroes. I'm currently trying to figure out if the Backup itself is also faulty, but since Testdisk found an MFT Backup written on the partition so I still have hope.
Update2: I just had the brilliant idea to hex view my backup as well and I had to realize that it is approximately 15228939010048 zeroes. This data is most definitely lost. Especially after "restoring" these zeroes over the entire drive a few times.
You know how when Linux boots up, you can press the delete key to jump from the graphical boot screen to a view of the kernel and init system logs? Is this possible with the KDE splash screen so I know what's going on with that too? I'd be happy with either a splash screen that can optionally be switched to a log view, or just removing the splash screen and having a log view permanently.
As the title says, I have tried many other Ubuntu based distros for fractional scaling but they all end up with blurry text. But when I tried KDE Neon it just blows it away- so clear and crisp! Long time linux user (mainly Mint) What does KDE do differently that others like Ubuntu, Fedora, Mint, PopOS don't?
I installed KDE Plasma on my PC and ever since the display brightness looks lower than what it used to be with GNOME.
Is this a thing?
Title.
Are there alternatives to https://extensions.gnome.org/extension/945/cpu-power-manager/ and https://extensions.gnome.org/extension/1082/cpufreq/ ?
I am aware that the same can be achieved by manually modifying files. Looking for a packaged solution.
Thank you
Edit : I'm sorry if this is not the right sub for this. If so please tell me where should I go.
Hi ! I tried KDE PM for the first time today. Wanted to resize a NTFS partition on a disk.
After 7 minutes stuck at 11% I lost patience and hit cancel. And it's still not canceled after 20 minutes.
Also it prevents the computer from shutting down normally.
What should I do please ? Is my data focked ?
So Wayland on KDE has been great for me so far, on Arch. What initially drew me in was VRR with a multi monitor setup, and having it work in games has been quite a treat!
My question/small issue is, I have two monitors, one is a Samsung Odyssey G7, which is notorious for being slow to wake from sleep, sometimes upwards of 7 seconds or so, while my second monitor is nearly instant. Well, my custom taskbars and widgets get switched up, which is a little annoying, but all I have to do is power cycle my other monitor and everything is back in the right place, but I'd much prefer to not have to do that.
A solution I could do is make them both the same. From what I have read, I understand that in Wayland there is no concept of a primary monitor, and forgive me for my lack of knowledge, but would there be a way to assign taskbars/widgets to a display via hardware identifiers, ie, taskbar/widget set on Y display, taskbar on Z display, if Y is powered off, those items migrate to Z display, but could it be made to work in reverse?
This only seems to happen because my main monitor takes so damn long to wake up, maybe to KDE or Wayland it looks as if another monitor has been connected, and treats that as the secondary, so I do see the logic in the behavior.
I should add the monitors are both 2560x1440p, and I am using a modern Radeon GPU, both displayport 1.4.
Hello everyone, newbie here.
I just switched to KDE Neon from Windows 10 and wanted to use a feature that i used frequently on W10: Laptop Wifi Hotspot.
I am currently connected via ethernet (with a USB-A adapter) and wanted to use my wifi interface to create an hotspot: the Network Manager interface lets me create an hotspot quickly, but my android phone can't manage to connect and just says it Timed Out during connection. It probably is stuck obtaining an IP address or some similiar issue.
I tried creating a new wifi for hotspot from scratch, with its own WPA2 password, I tried using something like "wifi-hotspot" available on GitHub etc, but the problem seems to be the same.
I hope someone can lend me a hand. Here are a few screenshots.
