If you have a script or application you want to run but don't have a desktop or dock launch icon for it, you can create a custom one yourself.
This will work in Gnome, KDE, and other desktops that follow the specifications at freedesktop.org.
For more options, you can read more about Desktop Entry Specifications.
Desktop entry location
There are a few primary places you should consider putting your desktop entry, depending on whether you want it available to everyone or just one user.
Desktop entry file
The desktop entry file is a simple text file.
The file should end with
.desktop. For example,
Here is an example template:
[Desktop Entry] # Application, Links (URL), or Directory (sub-group for applications) Type=Application Encoding=UTF-8 Icon=/path/to/launch_icon.png Name=MySpecificApp GenericName=SomethingGeneric Comment=This is a tooltip Exec=/thing/to/execute # To pass arguments use %u or %U # Exec=/thing/to/execute %u # Should run in a terminal? Terminal=false # Name of the window. Optional. See below. # Allows windows to stack # If this does not match, duplicate icons may show up in your dock StartupWMClass=name-of-app-window # Optional categories Categories=Development;Education; # If you want to have a special protocol handler. For example, # this is what Zoom meetings does to register zoommtg:// scheme # and to be associated with the x-zoom mime type # MimeType=x-scheme-handler/zoommtg;application/x-zoom; # X-KDE-Protocols=zoommtg # Optional actions (right click options) Actions=launch1;launch2;launch3 [Desktop Action launch1] Name=Launch normally Exec=/path/to/launch [Desktop Action launch2] Name=Launch with alt options Exec=/path/to/launch --alts [Desktop Action launch3] Name=Launch with alt options again Exec=/path/to/launch --otheralts
Get the name of a window
If you have issues with the windows not stacking on the launch icon in
your dock or favorites bar, you might need to set the
To get a window's name, first run the app so it is visible,
then open a terminal and run
xprop WM_CLASS. It will then wait
until you click on the title bar of a window and then it will print
the name of the window. For example:
xprop WM_CLASS # Then click on the window. # It will output something like: # WM_CLASS(STRING) = "code-oss-dev", "code-oss-dev" # Your entry would have the line: # StartupWMClass=code-oss-dev
You should now have the ability the create your own desktop launch icon for a Linux desktop. You should also have the resources to learn more about freedesktop.org standards.
