Can't add/edit programs to launcher

Question

Trying to edit a program to have a command specified before launching the program.

Adding it using MenuLibre doesn't work, manually doing it doesn't work, have tried rebooting several times.

Any edit to the main .desktop file (/usr/share/applications/obs.desktop) removes the program from the launcher (until I purge/reinstall as far as I can tell).

Edit: It seems as if it only doesn't like me adding the command before the program at the "exec" line. Works fine otherwise.

Edit2: Workaround: Have it execute a bash script with the command.

[Desktop Entry]

Version=1.0

Name=OBS

GenericName=Streaming/Recording Software

Comment=Free and Open Source Streaming/Recording Software

Comment[ru]=Бесплатная программа с открытым кодом для записи/трансляции видео

Exec=LIBGL_ALWAYS_SOFTWARE=1 obs

Icon=obs

Terminal=false

Type=Application

Categories=AudioVideo;Recorder;

StartupNotify=true

Answer 1

maybe you're having some problem with string interpolations. May you post the command you're trying to execute? If the command in Exec= is incorrect the launcher will not load the infos in myApp.desktop

One tip for testing if the command is actually working is using xlogo before anything else. The xlogo command opens a random window so we can have a graphical confirmation that it is indeed working.

ex. Exec=xlogo

There are two apps that may be helpful with this and similar tasks.

App Editor
Edit application entries shown in application launcher menu and their properties.

Alias
Simplify your commands: For example, you can create and organize a bunch of commands like the one that you're using now and just call it obs-config and then you would use like this: Exec=obsconfig obs

Answer 2

Change Exec=LIBGL_ALWAYS_SOFTWARE=1 obs

to Exec=sh -c "LIBGL_ALWAYS_SOFTWARE=1 obs"
