How do I close Discord in GNOME?
I don't know why nobody is aware this shortcut but here it is: Ctrl + q shuts Discord down.
Discord stays open as a background application with a system tray icon. The "Ubuntu appindicators" extension which is responsible for showing these icons, fails to show many app icons, electron based apps especially.
You may install TopIcons Plus extension to show the icon for Discord.
Click on the Cog icon(⚙️) in Left bottom to open User Settings.
Go to Linux Settings and disable "Minimise to Tray".
- Click on "X" to close the app.
To check whether app is running or not, look for "Discord" in System Monitor, or open a terminal and run
ps aux | grep discord
The output will show that no Discord process running now.
