Launch application using various icons with gnome desktop shortcut

[nlee2]

In ubuntu 17.10 gnome desktop, I made desktop shortcuts to launch an application with different parameter on the exec line. Each desktop shortcut uses a different icon to represent the parameter being passed. The proper custom icon is displayed in Activities and Favorites but when I launch the desktop shortcut it is the generic application icon that is displayed.

How do I create a shortcut that will use a different icon to distinguish between each exec parameter?

You could try the following, it might make a difference:

Append the --class parameter to your Exec entry in order to set a custom WM_CLASS for each .desktop file, e.g.:

Exec=my_executable --class=MyCustomClass1
and also add the following line to each .desktop file:

StartupWMClass=MyCustomClass1

Hope that helps

Thanks for the info. Unforunately vncviewer aka my_executable does not support --class parameter. What to do?

Got it working by using xprop to get the vm_class and use that class in StartupWMClass.
