Using the 4.0.4 AppImage on Debian 13 + GNOME 48. On first run, the window opened for settings. Now it runs in the background, apparently started automatically on login to GNOME. How would I reopen the window to change the settings? No .desktop file has been created. Executing the AppImage in a terminal does not do anything.
Some documentation on using the AppImage would be helpful.
do you have a Nextcloud icon in the menu bar? click on that, then (I think) the down-triangle in the middle of the dialogue that appears.
Good luck!
Thank you, your suggestion led me to a solution. I had to add a GNOME extension to display legacy icons.
This usually happens because the AppImage is already running in the background and doesn’t reopen its window when launched again. Check GNOME’s top-right system menu for Background Apps or a tray icon. If nothing appears, stop the running process using pkill -f AppImage in the terminal and then launch the AppImage again. Also check ~/.config/autostart/ to see if the app added itself to startup. Keep in mind that AppImage is only a packaging format—window behavior and autostart are controlled by the app itself, not AppImage. ![]()
