Bug#763609: gnome-shell: keyboard layout switching ignored after unplug/plug USB keyboard

[Ondřej Surý]

Package: gnome-shell
Version: 3.14.0-1
Severity: important

Hi,

since (roughly) GNOME 3.14 upgrade the keyboard layout switching is
non-functional.  After pressing SUPER-space the graphical switcher is
shown and you can switch the layouts, but it doesn't do anything with
the input - US keyboard is still used.  You can still set the layout
manually with 'setxkbmap cz' (for Czech keyboard), but the interface
between gnome-shell (or what takes care of it) and X input is broken.

It starts working again after a reboot, but unplugging and plugging
the keyboard starts the behaviour (or in my case unplugging the ASUS
USB dock and suspending the laptop).

It can be easily reproduced by unplugging and plugging the keyboard
back:

Quote from debian-devel:

Let me know if you have any idea how to debug the issue.

Cheers,
Ondrej Sury
