Dear Maintainer,
(I reported this at bugs.kde.org but they advised that I use reportbug and a
maintainer will forward upstream if appropriate.)
Several apps seem to not be launchable by krunner, KDE shortcut, or .desktop
file, unless they redirect stdout. I have no idea if this is the fault of the
apps or KDE or something else, but I report here in case it's the place.
Three examples:
If I start stellarium from the command line it works fine:
$ /path/to/Stellarium-25.1-qt5-x86_64.AppImage
If I start OBS (v31.0.4) from the command line it works fine:
$ flatpak run com.obsproject.Studio
If I start qjackctl (v 0.9.9) from the command line it works fine:
$ qjackctl
However if I make these .desktop files in ~/.local/share/applications/ :
[Desktop Entry]
Name=stellarium
Exec=/f2/sr/sa/Stellarium-25.1-qt5-x86_64.AppImage %F
Type=Application
Categories=
[Desktop Entry]
Name=obs
Exec=flatpak run com.obsproject.Studio %F
Type=Application
Categories=
...or I make this script in ~/bin:
#!/bin/bash
qjackctl
...and then I start any of them with krunner, or I assign a KDE shortcut to
them, they do not start.
*** HOWEVER, if I redirect their stdout somewhere, such as:
Exec=/f2/sr/sa/Stellarium-25.1-qt5-x86_64.AppImage %F > /dev/null
or
#!/bin/bash
qjackctl > tmp/qjackctl.log
...then they all work fine.
If stdout is not redirected, they all fail in different ways. For obs, journal
looks like this:
