Davide_sd's questions

I recently installed an application which I will use quite a lot, but it didn't come with a desktop launcher. I'm using Kubuntu 20.04 and I created the following paraview.desktop file in /home/myname/.local/share/applications/.

[Desktop Entry]
Categories=Education;Math;Science;
Comment[en_US]=ParaView allows viewing of large data sets
Comment=ParaView allows viewing of large data sets
Exec=/opt/paraviewopenfoam56/bin/paraview
GenericName[en_US]=Data Viewer
GenericName=Data Viewer
Icon=paraview
Name[en_US]=ParaView Client 5.6.0 OF
Name=ParaView Client 5.6.0 OF
StartupNotify=true
Terminal=false
Type=Application
Version=1.0

However, this launcher fails with the error Could not find the program 'paraview'.

If I run paraview or /opt/paraviewopenfoam56/bin/paraview in the terminal, they both works.

What can I try?

I'm trying to develop a KDE widget that should display a map. At the moment I can't get the widget to load, because of the errors module "QtLocation" is not installed and module "QtPositioning" is not installed.

I'm running Ubuntu 18.04. Looking at this page, I've made sure that libqt5positioning5 and libqt5location5 are installed. The widget still does not load with the above errors.

On reddit someone told me that I also need to install the QML bindings. What are the package names I need?

I'm looking for a way to run commands in a widget I'm trying to develop.

So far I've come across the org.kde.kio.KRun, which should be an interface to the kRunner. From the few examples I have seen, I only found that KRun has the following methods: openUrl, openService (which are not useful for running commands). I've tryed googling about it, but the only resource I've found is this one which seems to be very different from the org.kde.kio.KRun used in the widgets.

How can I run a command from a widget?

I'm trying KDE 5 and I'm spending significant amount of time looking at the System Setting shortcuts to find the name of the feature associated to a given key shortcut. Some shortcuts are interfering with some applications, where I cannot use the application feature I want because KDE have some feature associated with that shortcut.

Is there a way to search through KDE shortcuts list by the specific shortcut?

I'm a Gnome user and I'm trying KDE 5. When I was using Nautilus (Gnome), I had a bunch of shell script actions that worked on a list of selected file paths given by the variable $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS.

Reading this answer, I am aware that Dolphin actions provide the code %F: A list of files. Use for apps that can open several local files at once. Each file is passed as a separate argument to the executable program.

The problem is that Each file is passed as a separate argument to the executable program, while my scripts are designed to work with the variable $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS.

Ideally, I would like to reuse my old scripts. Is it possible to convert the Dolphin's %F list and set it as the variable $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS for my scripts?

I'm having problems with Eye of Gnome, the image viewer. I'm using Ubuntu 18.04. Unfortunately, the colors seems washed out, the images seem to lack contrast. This problem only happens with Eye of Gnome. If I use GIMP, Rawtherapee, Luminance HDR, ..., the colors are perfect.

I've used the following command: xprop -root -remove _ICC_PROFILE. This appears to temporarily fix the problem. When I start up the system again, Eye of Gnome is still affected by it. What can I do?

I would like to use a Nautilus script that calls a Python script of mine, passing as a required argument the path of the current folder. This would avoid me the trouble of refactoring the Python script to extract the folder path from the URI provided by $NAUTILUS_SCRIPT_CURRENT_URI. Ideally, I would like to have something like this.

#!/bin/bash
$current_folder=EXTRACT THE FOLDER PATH FROM NAUTILUS_SCRIPT_CURRENT_URI
python3  /path/to/my/file.py $current_folder -optarg 1

Where $current_folder is a required argument for my Python script, and -optarg 1 indicates that my script also accepts optional arguments.

How do I extract the current folder with bash script?
