I can run the appimage fine with the .desktop file but the icon does not show. I have resized it to 64x64 as well to check it wasn't a size issue. This is my .desktop file:

[Desktop Entry]
Name=Appium Inspector
Comment=Android app inspector
GenericName=Developer tool
Exec=/home/kieran/Applications/Appium-Inspector.AppImage
Icon=/usr/share/icons/hicolor/64x64/apps/appium.png
Type=Application;
StartupNotify=true

I have also run sudo update-icon-caches /usr/share/icons/* and it still appears blank.

The icon isn't even the grey cog one, it just appears blank. I'm running ubuntu 21.10. enter image description here

Desktop icon appears normally, but application opens into its own icon. Is this expected?

    Try AppImageLauncher instead of bicycle. See askubuntu.com/a/1125304/66509 .

  • Thanks so much, not only did it pull an icon file from somewhere else, I was able to change it to a custom one as well from the ~/.local/share/applications folder. However the application opens into it's own icon, is there anyway for it to open with the icon I have set, or is the icon in my favourites just a launcher for it?

To associate the running application with your .desktop launcher, you will need to explicitly set the StartupWMClass value to the WMClass of your application.

Run the application and determine its wmclass as follows. With Ubuntu 21.10 on Wayland, open the Gnome Shell looking glass by hitting Alt+F2. On the "Windows" tab, find the wmclass. When running Xorg, you can use the xproptool. Run the command xprop | grep WM_CLASS then click the window of your application.

Then edit the .desktoplauncher and add or edit the line

StartupWMClass=<wmclass>

so it indicates the wmclass you found.
