Does Dolphin on plasma 6.1 still support dolphin services? My installed services are no longer available after upgrade.
Following the accepted answer to this question, I have adjusted the ppa entry for geogebra to the following entry:
deb [signed-by=/usr/share/keyrings/geogebra.gpg] http://www.geogebra.net/linux/ stable main
This works very well, however occasionally the file /etc/apt/sources.list.d/geogebra.list seems to get overwritten and reverted to the old version:
deb http://www.geogebra.net/linux/ stable main
When is this file overwritten? How can I prevent this, without reducing the security level (meaning: I want the particular key to be usable only for the particular ppa and software)?
I am on (K)Ubuntu 23.10.
I have a GPD Pocket 3. This device has a rather small screen. Under ubuntu 23.10 when running Libreoffice and entering tools options, I get the following screen:
On my bigger laptop (albeit on Kubuntu 23.10) I get:
How could I reconfigure Libreoffice to get the full picture on the smaller device. Alternatively, how could I see the lower part of the screen?
PS: Screen resolution is 1920 * 1200 on both screens. On the first one settings a set to scale 200% (which works well for me in most circumstances).
Xkill is a utility program distributed with the X Window System that instructs the X server to forcefully terminate its connection to a client, thus "killing" the client.[1] When run with no command line arguments, the program displays a special cursor (usually a crosshair or a skull and crossbones) and displays a message such as
Select the window whose client you wish to kill with button 1 ...
If a non-root window is then selected, the server will close its connection to the client that created that window, and the window will be destroyed.
I would like to achieve the same behavior for wayland windows, if possible.
PS: I am on Kubuntu 21.10 running a wayland session, but would prefer something DE agnostic.
The question sounds similar to the unanswered question Is it possible to connect my phone via bluetooth and then call through the computer? and my purpose is similar. However, I was thinking about using WLAN or even the USB to connect my phone to the desktop.
The purpose is to make and take a call via the desktop, using the Bluetooth headset which is attached to the desktop.
What I have tried:
- See if KDE Connect supports this. (This would be ideal, but does not seem to be the case.)
- Check if scrcpy supports this. This seemed like a promising solution, but scrcpy does not transmit audio and usbaudio seems to transmit only from the phone to the PC (have not verified this).
- I saw the similar question How to set up Ubuntu PC as bluetooth headset to attend calls but did not understand how this is supposed to work. (Would both devices be connected via Bluetooth to the desktop?)
I am on Kubuntu, and would prefer a solution working on both 18.04 and 19.10.
I have created an ssh tunnel in such a way, that I can access my shares by typing
smb://bruni@localhost:9000/
into the filemanager (dolphin). The tunnel works.
I would like to mount this share. The following command does not work:
sudo mount -t cifs -o credentials=/root/.credentials,uid=bruni,gid=users,vers=1.0 //localhost/users /home/bruni/mountpoint/
Obviously I need to specify the port somewhere. How can I modify the above command so that it works?
Recently Okular has become a great tool to annotate pdfs.
I have added some annotations (stamps) using okular to a pdf. I would like these annotations to become flat. By flat I mean that they are no longer selectable and deletable so that they are not distinguishable from the original pdf.
A Bug report has been filed on the KDE bugtracking system.
I would like the KDE Calendar widget to display the calendar events from my egroupware calendar (Caldav) which I have configured in Lightning (This is no longer required in Thunderbird >=78). The server uses TLS client certificate authentication which is not supported in KOrganizer, even though well voted for respective bugs exist since 2006. Therefore, I cannot directly connect the calendar to KOrganizer.
PS: Kubuntu 21.10, Plasma 5.22.5, Thunderbird 91.5, but all this should be rather irrelevant
Update: I have managed to create an .ics file calendar in Lightning that is accessible to KDE. if someone tells me how to synchronize locally two calendars in lightning that would be a complete solution. Alternatively, if I could automate exporting from Lightning to an ics file (overwriting the old one), this would also be a complete solution.
After updating to Kubuntu 19.04 each time I open dolphin, a process called thumbnail.so is using up 100% of my cpu. It respawns when I kill it, without closing dolphin.
I have a webdav share mounted with davfs2. This share is quite big, but it does primarily contain files that should not be thumbnailed.
This was no problem prior to the update.
It seems that the problem arises when I open a file in dolphin with libreoffice...
Krusader does not exhibit this problem.
PS1: it seems to use up that much CPU in particular when I access a mounted webdav share. Though the mounted folders contain mainly spreadsheets and odt documents, for which I have not enabled previews.It also seems to be triggered by opening a file with libreoffice on the mounted share.
PS2: persist after update to 19.10
How to combine multiple CSV files to one ods file, one sheet per file. I have ten CSV files and I would like to combine them to one ods file comprised of ten sheets, one per original CSV. This should be done on the command line.
I would like to split a spreadsheet (ods or xlsx) into multiple csv files, one for each sheet in the spreadsheet.
I would like to do this without launching a graphical app and preferably in a one liner.
Any ideas?
Though the linked duplicate provides a possible solution in one of the answers (not in the accepted one) and was helpful. The solution does not work with ODS files as I requested, and I consider the question to be sufficiently different.
In KDE I would like to add the EU flag to the layout switcher for the EurKey layout:
Is this possible (without recompiling anything)?
P.S.: The above is on Kubuntu 18.04, but I am quite sure that a solution would be the same on all currently supported versions of Kubuntu.
Yesterday, while trying to unmount our (davfs2 mounted) work webdav server from my filesystem, I got device is busy.
Running sudo lsof | grep /mountpoint/of/davfs, revealed that the culprit was updatedb. Running man updatedb revealed that this is a command run to update a database for mlocate, most probably invoked by cron.
While I sometimes use locate, i don't need it to include all files on our work server (we got other search tools for that), and I definitely do not want this to interfere with me unmounting the filesystem.
I have a GPD Pocket running Ubuntu 16.04 LTS with Unity and Firefox Quantum. The GPD pocket is a small netbook (7 inch display). For some sites I would therefore prefer seeing on this screen the mobile version of the website (mainly on my work's egroupware server).
How is this possible?
Bonus question (but neither necessary nor sufficient to get the accepted answer): How to do this on Google Chrome/chromium?
I do not care if this is a per website or a global setting as I use different firefox profiles for different things.
The following problem persists even after upgrading from 17.10 to 18.04:
After upgrading my Kubuntu 17.04 to 17.10 by running
do-release-upgrade
I get the following error message after each reboot.
Error found when loading /etc/profile:\n\n/usr/share/im-
config/data/21_ibus.rc line 6: /usr/bin/ibus-daemon: No such
file or directory\n\nAs a result the session will not be configured correctly.
You should fix the problem as soon as feasible.
cat -n /usr/share/im-config/data/21_ibus.rc
Line 6 reads:
IBUS_ENABLE_SYNC_MODE=0 /usr/bin/ibus-daemon --daemonize --xim --address 'unix:tmpdir=/tmp/ibus'
Unfortunately I don't know what this is. Indeed there is no file /usr/bin/ibus-daemon
Also:
bruni@Inspiron-5547:~$ sudo apt purge ibus

Package 'ibus' is not installed, so not removed

How could I fix the problem as soon as feasible?
why is there a /usr/share/im-config/data/21_ibus.rc used when ibus is not installed?
EDIT I guess the culprit in my /etc/profile is the file /etc/profile.d/input-method-config.sh
This reads:

I guess the problem is that $GTK_IM_MODULE returns ibus, even though ibus is not installed and not used.
Installing ibus removes the problem described in the question at hand, but leads to the more severe problem described in this question, so I removed ibus again.
Is it possible to add plasmoids to the latte dock? I have seen screenshots where this seems to have been done. I would be particularly interested in adding a keyboard layout indicator.
According to this extract of the documentation of VeraCrypt, it is possible to create a portable "Traveler Disk" in the application:
Tools -> Traveler Disk Setup
You can use this facility to prepare a special traveler disk and launch VeraCrypt from there. Note that VeraCrypt ‘traveler disk’ is not a VeraCrypt volume but an unencrypted volume. A ‘traveler disk’ contains VeraCrypt executable files and optionally the ‘autorun.inf’ script (see the section AutoRun Configuration below). After you select Tools -> Traveler Disk Setup, the Traveler Disk Setup dialog box should appear. Some of the parameters that can be set within the dialog deserve further explanation:
My problem is I can't seem to find Tools → Traveler Disk Setup.
Am I missing something? I want to be able to share files on this disk with people running MS Windows.
After having updated Kubuntu from 16.04 (with kubuntu backports ppa enabled) to 16.10 my keyboard does record only a few keys (it ignores most keystrokes).
This happens only in plasma (e.g. Krunner, Application launcher,password dialogues). However, this does not happen in the terminal and in applications (e.g. Libreoffice, firefox, guake, telegram, plasma-discover, kate).
The behavior is irrespective of the keyboard layout chosen (DE,GR,US)
Nonetheless it is very annoying as
- I am used to using Alt-F2 + typing to open my applications
- I cannot run any GUI applications requiring root (e.g. my own scripts to mount my work network places into my filesystem)
What I have done
Deleting all files under ~/.config containing plasma by running rm *plasma* did not change anything.
Similarly, deleting all files under ~/.cache containing plasma by running rm *plasma* did not change anything.
When I run
killall plasmashell #to stop plasmashell
kstart plasmashell #to restart plasmashell
killall krunner #to stop krunner
krunner #to start krunner
and the following to restart polkit-kde-authentification-agent-1
killall polkit-kde-authentication-agent-1
/usr/lib/x86_64-linux-gnu/libexec/polkit-kde-authentication-agent-1 &
as described in this bug, the aforementioned problems seem to be resolved.
However, they reappear on each restart. Any ideas?
uptime
shows among others 4 users, should I be worried?
According to man uptime
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
Is there a way to find which four users are "currently logged on"?
I use the following command to print a directory structure to a file:
tree -h somepath/ > tree_of_somepath.txt
tree gives a nice colorized output on the terminal, but as expected this cannot be redirected to a text file. I would like to print the output of tree to a pdf file and preserve the color.
Any ideas?
