Bonjour, I'm relatively new to linux and have some problems.
A) Cannot modify KDE Plasma launchers.
Though I can launch from a terminal session, the modifications I write to the launchers through their "properties" are not saved. I'm a member of groups sudo and adm I've tried modifying the permissions (chmod ... ) without success.
user@user-kubuntu-pc:~/Desktop$ ls -l
total 0
lrwxrwxrwx 1 user user 39 Aug 24 15:17 jamulus.desktop -> /usr/share/applications/jamulus.desktop
lrwxrwxrwx 1 user user 46 Aug 24 15:17 jamulus-server.desktop -> /usr/share/applications/jamulus-server.desktop
user@user-kubuntu-pc:/usr/share/applications$ ls -l
(...)
-rwxrwxrwx 1 root root 649 Jul 29 11:56 jamulus.desktop
-rwxrwxrwx 1 root root 783 Aug 25 22:10 jamulus-server.desktop
(...)
How can I permanently modify launchers ?
B) Cannot use my environment variables with KDE.
In the launchers and the terminal, the path to my hard disk files is rather long and I'd like to use an environment variable to shorten it.
I set $J_DAT="/media/user/Disque Dur/Media/My Music Tech and Other/Jamulus" and export it, but KDE seems to ignore it.
How do I tell KDE to use my environment variables ?
Context :
tower pc booting from Windows (SSD) or Ubuntu (SSD), sharing data on Windows NTFS hard disk.
Ubuntu 22.04 LTS with KDE Plasma 5.24 LTS was recently installed for me.
I then installed Ubuntu Studio over it.
I then installed jamulus (online internet jamming, audio).
Jamulus client and server may be launched with parameters;
client ex.: jamulus -i "/media/user/Disque Dur/Media/My Music Tech and Other/Jamulus/JamulusL.ini" ).
Jamulus installed 2 desktop launchers for it's client and server.
Thanks in advance for any help.
