Description

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'm pretty sure it's something related to the xapps library, which is why I opened an issue in its repository: https://github.com/linuxmint/xapps/issues/63 . I thought of opening one here too just for reference for anyone experiencing this.

Configuration:

  • Cinnamon version: 4.0.8
  • Distribution: Arch
  • Graphic card and driver: Intel HD Graphics 620, driver i915
  • Linux 4.18, 64 bit

Relevant .xsession-error:

Research direction

Start with applet.js at _syncGroup around lines 265-269 and review the reported .xsession-error output. Compare the failure with the related xapps issue 63 to determine the affected component. Done means the keyboard layout applet stays loaded, layout switching works, and the reported errors no longer occur.
