A couple of months ago, I installed Microsoft Teams app in my Debian buster machine for a online meeting. The application worked fine, but it always started up automatically when launching the GNOME desktop environment. The behavior is quite annoying for me, because it take quite long time for the desktop to be ready for my normal use with the machine being rather old and its storage is HDD. But I couldn't find the settings or properties within the gnome-control-center setting items. Today I find another way to stop automatic launch of the Teams app. Applying the patch below to the ~/.config/autostart/teams.desktop file would work fine: 12c12 < X-GNOME-Autostart-enabled=false --- > X-GNOME-Autostart-enabled=true Thanks to those blogs and articles: Gnome Desktop Entry Format extensions - bootlegged documentation ArchWiki 自動起動
