I'm getting back into Linux and am running Kubuntu 21.10, and I want to make a proper full backup of the system now that I've configured it how I like. This is the command I used to create a backup on a separate drive: sudo rsync -aAXv / --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} "/media/backuppath/" This is what my partitions look like for the drive I want to back up: /dev/sda1 fat32 /boot/efi (primary) /dev/sda2 extended /dev/sda5 ext4 / I am new to rsync, so it would be helpful to know if this backup command will take care of everything to restore an exact system backup: system settings, installed programs, etc. More importantly, what do I need to run to restore this if the time ever comes?

Someone suggested I direct a copy of the unmodified X display to a file and afterwards convert that file to a general purpose video file. What commands would I use to do this on a Kubuntu system? (Edit: He said something about attaching a display port to a file.) If not possible, what is my best option for an excellent quality screen recording that does not depend on fast hardware? *Background:* I tried using avconv with -f x11grab and some GUI programs. However, no matter what I try, the resulting video either has artifacts/ blurriness or is choppy (missing frames). This is probably due to CPU/ memory constraints. *Goals:* - Video quality must not be noticeably different from seeing the session directly on a screen, because the purpose is to demonstrate an animated application. - The final video must be in a common format that can be sent to Windows users and used on the web. I think H.264 MP4 should work. - The solution should not presume much prior knowledge. I am familiar with the command line and basic Linux commands, but I am still learning Linux and do not know much about video codecs. *What I already tried:* - Best command so far: ffmpeg -f x11grab -s xga -r 30 -i :0.0 -qscale 0.1 -vcodec huffyuv grab.avi, then convert to mp4 with ffmpeg -i grab.avi -sameq -vcodec mpeg4 grab.mp4. - The picture quality is great, but on my test sytem it lags the computer. On a faster target system it does not lag, but frames are obviously skipped, making the video not very *smooth*. - I am still trying to figure out how to save the grab.avi file to SHM to see if that helps. - Using Istanbul and RecordMyDesktop GUI recorders - Simple command: avconv -f x11grab -s xga -r 25 -i :0.0 simple.mpg using avconv version 0.8.3-4:0.8.3-0ubuntu0.12.04.1 - Adding -codec:copy (fails with: Requested output format 'x11grab' is not a suitable output format) - Adding -same_quant (results in great quality, but is very choppy/ missing many frames) - Adding -vpre lossless_ultrafast (fails with: Unrecognized option 'vpre', Failed to set value 'lossless_ultrafast' for option 'vpre') - Adding various values of -qscale - Adding various values of -b - Adding -vcodec h264 (outputs repeatedly: Error while decoding stream #0:0, [h264 @ 0x8300980] no frame!) - Note: h264 is listed in avconv -formats output as DE h264 raw H.264 video format

I want to run Firefox as different users (Kubuntu 24.04). I've created extra users, then I do $ xhost +SI:localuser:NEW_USER $ sudo -u NEW_USER firefox I get this error message: /user.slice/user-1000.slice/user@1000.service/app.slice/app-org.kde.konsole-32c90ac053c74c8b88698b978c0ba6b5.scope is not a snap cgroup Digging, I've come across these: how to make it possible using SSH and using systemd-run The SSH method works, but I don't want to go that route. Now, I run this command: systemd-run --uid=1001 --slice=user-1001.slice /bin/sh /path/test.sh test.sh writes into a file that only user uid 1001 has access to, and then starts firefox. Checking, content gets written, but Firefox doesn't run. Checking with ps, there's no firefox process. How can I get Firefox (installed as a snap) to run as a different user?

I mount four servers (3 via cifs, 1 via sshfs) using autofs. auto.master /- /etc/auto.all --timeout=60 --ghost auto.all /mnt \ /server1 -fstype=cifs,rw,credentials=/etc/.smbcredentials.txt,uid=1000,file_mode=0775,dir_mode=0775,users ://server1/ \ /server2/ -fstype=cifs,rw,credentials=/etc/.smbcredentials.txt,uid=1000,file_mode=0775,dir_mode=0775,users ://server2/ \ /server3 -fstype=cifs,rw,credentials=/etc/.smbcredentials.txt,uid=1000,file_mode=0775,dir_mode=0775,users ://server3/ \ /server4 -fstype=fuse,rw,allow_other,uid=1000,users,reconnect,cache=yes,kernel_cache,compression=no,large_read,Ciphers=arcfour :sshfs\#user@server\:/home ``` Everything is fine when I make a clean boot. I connect to my network (using a VPN) and autofs mounts everything. # Problem When there is a network disconnect, e.g. when I hibernate my laptop or connect to a different network, autofs causes my explorer (dolphin) to freeze because it tries to load the remote share infinitely. It becomes unresponsive and does not even react to SIGTERM commands. Sometimes I am lucky and calling sudo service autofs stop and sudo automount helps to resolve the issue. However, often it still stays freezed. Sometimes even, my whole dock freezes due to this making all applications unselectable. Then I have to make a full reboot.. I've searched for weeks now for solution how to deal with autofs in such situations. Before using autofs, I had everything mounted via /etc/fstab but that also required a manual remount after every network interruption. I thought autofs would help me here but it causes me even more trouble. # Questions 1. Is there any point I overlooked that could solve the freezing problem? 2. Is there a completely different approach that may be better suited for my situation than autofs? PS: I'm on Kubuntu 16.04

I have some problems installing Nvidia drivers on my Kubuntu system and to get them working (GPU-Model: GeForce GTX 980 Ti). I tried it first in the standard way: $ sudo add-apt-repository ppa:graphics-drivers/ppa $ sudo apt-get update $ sudo apt-get install nvidia-driver-450 The installation finished, but after restarting, the new drivers don't work very well. I'm using a 4K monitor with 3840x2160 (16:9) resolution, but with the driver in use, it only allows for a resolution of 1024x768 (4:3), so my whole screen gets distorted. Also, the command nvidia-smi fails: NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running. Furthermore, after removing the drivers manually and restart, everything is back to normal. I tried with this method instead: $ sudo ubuntu-drivers autoinstall, but I get the same results. Then, I tried to execute the runfile provided by NVIDIA on their download site, but it fails because it is unable to disable Nouveau (the current Kernel driver in use). I also executed this command: lspci -vnn | grep VGA -A 12 to check. This is what I get when running normal: And here the same output with NVIDIA drivers enabled: 01:00.0 VGA compatible controller : NVIDIA Corporation GM200 [GeForce GTX 980 Ti] [10de:17c8] (rev a1) (prog-if 00 [VGA controller]) Subsystem: NVIDIA Corporation GM200 [GeForce GTX 980 Ti] [10de:17c8] Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at f6000000 (32-bit, non-prefetchable) [size=16M] Memory at e0000000 (64-bit, prefetchable) [size=256M] Memory at f0000000 (64-bit, prefetchable) [size=32M] I/O ports at e000 [size=128] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: Kernel modules: nvidiafb, nouveau 01:00.1 Audio device : NVIDIA Corporation GM200 High Definition Audio [10de:0fb0] (rev a1) Subsystem: NVIDIA Corporation GM200 High Definition Audio [10de:17c8] Any advice how to get the NVIDIA drivers installed and working on Kubuntu? I tried pretty much every installation guide, but none of them really worked.

I am running KDE on Kubuntu 24, with default settings for almost everything. I am trying set up shortcuts to be Windows-like, as I am used to but I have gotten stuck on a weird bug. When I set Ctrl+Shift as the shortcut to change keyboard layouts, the Ctrl+ShiftLeft or Right combination (for selecting the whole word) stops working. If I set Alt+Shift as the keyboard layout change shortcut, the Alt+Shift+Tab combination (switch back to previous task) breaks. I have now set the shortcut to switch layouts to something weird and inconvenient so make the others work, but it feels like bug that must've been fixed by someone years ago. So the question is - is it really fixed? Or, at least, is there a workaround?

I've just installed Kubuntu (so using KDE Plasma) and I straight-away noticed that the scaling was a bit messed up.

My setup is a 15" 1920x1080 144Hz laptop screen and a 27" 3480x2160 60Hz external monitor. I'm currently using X11 as a display server.

On the laptop screen things are just too big and on the external one some are okay and some are not. For example, when I opened Firefox everything was just too small, but on Google Chrome everything was just fine. I tried going into the settings and tried to change the "global scale" setting, but it does nothing.

Can somebody help me? Thanks

EDIT: I tried installing Wayland and the scale works, but everything gets blurrier. Also, now on the laptop screen the scale is correct. On the external monitor, instead, everything is now smaller, apart from the taskbar.

I installed Kubuntu 20.04 on my brand new machine MSI MEG X570 ACE motherboard with Intel Wi-Fi 6 AX 200 n/w card. There is no Windows installed no double booting only Kubuntu. When I try to connect to my home wifi I get following error. How can I fix this? kernel specs:

I'm struggling to install Kubuntu 15.04 on my PC. I've got a GTX 970 which i think is throwing off the trial mode from starting up. nomodeset doesn't work, so I tried nouveau.noaccel=1 to beget this error screen. At this point I don't fully understand how to proceed, so any help would be great.

I've recently set up a new computer running Kubuntu 25.04 (KDE 6.3.4), and I have a few .desktop files I've brought over from my previous computer (which was using Gnome), where they worked fine. However, now I can't get them to be launchable. They're basically just designed to launch Chrome with a few specific settings. For example:

[Desktop Entry]
Categories=Network;Chat;
Comment[en_US]=A shortcut for Disney+
Comment=A shortcut for Disney+
Exec=/home/ross/scripts/disneyplus.sh
GenericName[en_US]=
GenericName=
Icon=/home/ross/Pictures/icons/disney-plus-logo.png
MimeType=

Name=Disney+
NoDisplay=false
Path=/home/ross/scripts/
StartupNotify=true
Terminal=false
Type=Application
X-KDE-SubstituteUID=false
X-KDE-Username=

which points to a script with the contents:

google-chrome --disable-extensions -url http://disneyplus.com  -start-fullscreen &

The script works fine from the command line. The .desktop file is set to be executable, but the Allow Launching option doesn't appear on the right click menu. [context menu for the .desktop file](https://i.sstatic.net/X8UxCgcg.png)

$ desktop-file-validate disneyplus.desktop

reports no errors. Most of what I've found online so far suggests using gio to set the trusted flag from CLI, but that isn't working:

$ gio set disneyplus.desktop metadata::trusted true
gio: Setting attribute metadata::trusted not supported

I don't know what else I can try. Does anyone have any ideas?

After upgrading Kubuntu from 18.04 to 18.10 and that to Plasma 5.14.5 through the "backports" PPA I am lucky enough to face almost no bugs, except annoying notifications saying "kdeinit5 closed unexpectedly" It happens when I take some normal actions in Dolphin: start a new window, new tab, split, refresh. It seems to me that those actions are related to the Dolphin *window*; creating a new folder or deleting something doesn't trigger the error. I read here that kdeinit5 is a process launcher that executes KDE programs and kdeinit loadable modules (KLMs) starting them more efficiently. Using kdeinit5 to launch KDE applications makes starting a typical KDE application a couple times faster and reduces memory consumption by a substantial amount. - But as far as I can tell only Dolphin reports a problem with that. I have not noticed Dolphin operation or that of any part of the desktop being affected at all by this, I would just like to avoid seeing those notifications. Of course, I would like to have a solution that would avoid the error in the first place, but - if that is not possible until a future update etc - I am mainly asking here for a way to simply make those notifications go away. --- I don't know how to debug this, or if the following is useful, but running kdeinit5 dolphin the file manager starts with the usual error while in terminal I get this: ~$ Trying to convert empty KLocalizedString to QString. qt.accessibility.core: Cannot create accessible child interface for object: PlacesView(0x55d3d75565c0) index: 14 kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/trash.so' from launcher. kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/trash.so' kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/file.so' from launcher. kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/file.so' kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/file.so' from launcher. kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/file.so' kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/thumbnail.so' from launcher. kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/thumbnail.so' kf5.kio.trash: Root trash dir "/media/cip/DEPO/.Trash" exists but didn't pass the security checks, can't use it kf5.kio.trash: Directory "/media/cip/DEPO/.Trash-1000" exists but didn't pass the security checks, can't use it Qt: Session management error: networkIdsList argument is NULL Could not find video stream decodeVideoFrame() failed: frame not finished KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = kdeinit5 path = /usr/bin pid = 12077 KCrash: Arguments: /usr/bin/kdeinit5 thumbnail local:/run/user/1000/klauncherFKnizM.1.slave-socket local:/run/user/1000/dolphinFjEuPw.5.slave-socket KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi from kdeinit sock_file=/run/user/1000/kdeinit5__0 kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/libexec/drkonqi' from wrapper. kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/libexec/drkonqi' kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/thumbnail.so' from launcher. kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/thumbnail.so' Qt: Session management error: networkIdsList argument is NULL

I am on Kubuntu 24.04 and I see when I open my Chrome browser the indication that New Chrome available and Chrome is out of date I don't see chrome reported in my software updates so I run the following command: $sudo apt-get update $ sudo apt-get --only-upgrade install google-chrome-stable Reading package lists... Done Building dependency tree... Done Reading state information... Done google-chrome-stable is already the newest version (129.0.6668.70-1). The following package was automatically installed and is no longer required: mailcap Use 'sudo apt autoremove' to remove it. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. My browser was closed when I run this and when I reopened it I still see the indication on my top right part New Chrome available. When I check in the help menu the version reported is Version 129.0.6668.70 (Official Build) So what is the issue here? Is there a way to fix this? If not, how can I re-install Chrome and can I do it without losing my accounts that I log in? **UPDATE in response to the answer from user10489** There is a file named: google-chrome.list.distUpgrade and when I see the content it says: ### THIS FILE IS AUTOMATICALLY CONFIGURED ### # You may comment out this entry, but any other modifications may be lost. # deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main # deactivated during upgrade in noble

I am using KDE Neon LTS 5.12, sometimes, for some unknown reason, I can see a high CPU usage that comes from started konsoles by kdeinit5. Every konsole has no window and uses up to 17% CPU approximately. As I do not know the reason this happens, sometimes I see one, or two, or 4 konsoles (17% * 4 = 68% CPU usage) with the same description: konsole [kdeinit5]. [![konsole [kdeinit5] problem]] It says I am the user who started these, but I do not know what do I do that makes this happen. If I try to [Jump to the parent process] in the context menu, It redirects me to the obvious kdeinit5: Running... process. [![konsole [kdeinit5] problem]] I have been checking forums but did not found a solution yet. ### UPDATE (2018-04-17) I am still testing, I have already installed the same distribution with almost the same configuration in a laptop, with **just one difference: did not install the Nvidia drivers** both my desktop computer (the main PC used in this post) and the laptop are using Nvidia GPUs. For some reason (again), seems to work perfectly well, without lefting processes in background nor initializing new ones. Obviously, there is a performance loss that can be slightly recovered by setting the composer to Xrender, but even... Is reported some kind of error related to this? I have tried other distros, but not as much to tell if this error is reproduced in those as well. Will keep testing.

After my recent upgrade attempt from 20 to 22 to 24 I got an installer error at the very end of the process (22 to 24) and now I'm left with several packages which were not configured normally. After spending several days trying to figure it out I gave up and asking for more or less step by step instructions on what to try to fix the issues.

For health reasons, i mapped the mouse buttons on keys on keypad. This helps me, but I have solved the bindings via xdotool in KDE Custom shortcuts. With e.g. xdotool click 1 you can simulate simple mouse clicks, but I would also like to drag a window when the mouse button is permanently pressed. Under windows this was possible with AutoHotKey. Is there an option to set this up in linux as well? I use Kubuntu 20.04 and KDE 5.

I used to bind mount my /usr from another volume, as my root volume is almost full. However, with KUbuntu 22.04.1 LTS, I.e., systemd ver 249.11, I found it impossible now. Here is how I did it before in /etc/fstab:

LABEL=bigvol    /bigvol         auto defaults,noatime,nodiratime,barrier=1,ro  0 2
/bigvol/d-sys/2023-02/usr  /usr auto bind,ro       0 0

I.e., with 0 2, the /bigvol volume is mounted on boot up, and with 0 0, the /usr volume is not mounted until later. It's been working like that for over 10 years, but with systemd ver 249.11+ under linux-image-5.15.0-60, it starts to *bind* mount the /usr volume before any other volumes has been mounted, even when the root volume is temporarily mounted as /root instead of as /. **UPDATE:** So I tried the suggested /bigvol/d-sys/2023-02/usr /usr auto bind,ro,x-systemd.requires-mounts-for=/bigvol 0 0 And it is _not_ working, stopped at the _same_ place when the root volume is temporarily mounted as /root instead of as /. But Freddy's answer looks so convincing that I tried something else -- using the exact same syntact to bind mount something else (comment out this /usr bind mount but added another bind mount directory /var/cache/apt/archives). And, it, works! So it seems that 1. systemd knows that the /usr volume is very special and should be mounted _before_ anything else. 1. but it fails to see that my /usr volume is only a bind mount should be mounted _after_ anything else.

I attempted to install Yakuake and Konsole using Flatpak due to issues with the default installation, which produced garbled output and occasional blank lines, resulting in inconsistency. After successfully installing both software packages via Flatpak, they function flawlessly, but there's a slight inconvenience related to settings. In the native installation, when I modified settings for one application, those changes were automatically applied to the other. However, this seamless synchronization doesn't occur with their Flatpak versions. I now need to manually configure the same settings for both applications, which adds a bit of extra effort. If anyone has insights or solutions for this situation, I'd greatly appreciate your input.

i'm trying to set a specific resolution for kms, at boot time. by default kms choose the highest resolution available (2500x1600) which is a bit hard to read. i'd like to set 1440x900 instead. i tried two things via grub, the first one:

GRUB_GFXMODE=1440x900
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_GFXPAYLOAD_LINUX=1440x900

but that didn't help, the system act just the same, no matter if it is there or not, it just continue to use 2500x1600. the other thing i tried instead is setting a kernel parameter like so:

GRUB_CMDLINE_LINUX_DEFAULT="video=1440x900"

that kind of helped a bit, the resolution changed, it's much better and readable but then, the virtual_size didn't change accordingly, it's still 2500x1600, meaning my tty is much bigger than the screen itself and so i only see the upper_left part of a larger term. how can i force kms to a specific resolution ? thanks

I have Kubuntu 22.04.2 LTS. In the past few weeks, KDE started to 'freeze' occasionally. Is this a known issue? Is there any way how I can gracefully close/restart just the UI from terminal? But most important, what should I check to collect some useful logs or details that could help to determine the cause of the problem? Detailed description: KDE just gets stuck, and I can not do anything in the graphical UI. It seems that this usually happens when I switch desktops or even windows on the same desktop, but I cannot reproduce the behavior on-demand. I can move the mouse cursor, the music is still playing in the background (clementine - and I can control it via keyboards shortcuts), I can log in to the console using Ctrl+Alt+F1, I can log in via SSH, but I can not control KDE anymore: I can not move windows, switches desktops, close windows, opening apps or anything similar. Once this happened during a Skype call and the call was not interrupted and I was able to communicate. This started to happen only few weeks ago, it hasn't been happening before. I haven't installed any new hardware lately. Technical details that might be relevant:

I have 128GB of memory overclocked to 3600MHZ, but I have had it like this for 3 years without an issue. Also, memtest seems ok -- memtester 1G 10.

See below why this is not a duplicate: being about top-button, which is not sufficiently specified by the xev -event button command. I have a touchpad with 4 buttons, the top ones doind the same thing as the bottom ones. I want to remap the top ones (namely the right-top button) to make a middle click. I have followed this solution: ~$ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ATML1000:00 03EB:8A5C id=9 [slave pointer (2)] ⎜ ↳ PS/2 Generic Mouse id=11 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)] Then: xinput get-button-map 12 1 2 3 4 5 6 7 Using xev -event button | grep button all I can get is that both right buttons do the same thing (3) - and what I want (middle-click) would be 2. The problem is that the accepted solution there is simply to replace 3 with 2 - but if I do that with something like xinput set-button-map "SynPS/2 Synaptics TouchPad" 1 2 2 4 5 6 7, only the right-*bottom* button is affected: it becomes a "middle-click", while the top one stays the normal "right-click". What I want is the bottom one to remain default (right-click), and the top (right) one to become a "middle-click". It seems that the touchpad top buttons are not listed by xinput get-button-map 12 (replacing 4, 5, 6 or 7 doesn't affect them either). So my question is not simply how to remap an obvious button like the right click to middle click (like here ), it is about treating the top buttons separatelly from the bottom ones. How could I list the top-button coordinates? - and then change and save their setting? I mean not list just what they do, but their difference from the bottom buttons so that I can apply the ”middle-click” option just to the top. This is in Kubuntu 24.04.
