xapp_kbd_layout_controller_get_current_group assertion fails

Inizia tracciando xapp_kbd_layout_controller_get_current_group e le chiamate a _syncGroup dell’applet della tastiera in applet.js:265-269, utilizzando l’output segnalato di .xsession-error come contesto di riproduzione. Determina perché il controller viene disabilitato e verifica che l’applet e la scorciatoia per cambiare il layout della tastiera rimangano utilizzabili senza assertion o errori relativi a elementi non definiti.

Hi there,

at a seemingly random point during the Cinnamon session the keyboard layout applet disappears and cannot be loaded anymore. The keyboard shortcut to switch between layouts stops working too.
I think this is due to something going wrong in xapp-kbd-layout-controller.
Here's some suspicious error log in .xsession-error:

The main culprit being xapp_kbd_layout_controller_get_current_group: assertion 'controller->priv->enabled' failed. Why did that assertion fail? What can be done about it?

My configuration:

• Linux 4.18.7-zen1-1-zen
• Arch Linux (current, except kernel and graphic card drivers)
• Cinnamon 4.0.8
