shift_caps_switch doesn't work in Ubuntu 18.04

[Yuriy Vidineev]

setxkbmap -layout us,ru -option grp:shift_caps_switch #nor CapsLock, neither Shift+CapsLock does nothing
I've tried to set it via Gnome Tweak Tools and DConf editor - it doesn't work as well.

While only one cups switch works

setxkbmap -query
rules: evdev
model: pc105
layout: us,ru,us

Just tested liveusb with ubuntu 18.10 - bug can be reproduced there as well

[Yuriy Vidineev (adeptg)]

Tested with Fedora 29 liveusb - the same bug
KDE Neon 20181011 User - no such bug. Looks like it's something in Gnome

[Timo Aaltonen (tjaalton)]

I think you need to set these via the gnome config, otherwise g-s-d will reset the settings

[Yuriy Vidineev (adeptg)]

Yes, I've set it via Gnome Tweak Tools - it just doesn't work.
I've found similar bug report for elementary OS: https://github.com/elementary/switchboard-plug-keyboard/issues/75

Most interesting answer is:

This method is not available because Gnome components doesn't support it (you can see all available methods here https://github.com/GNOME/mutter/blob/master/src/core/keybindings.c, using "g_str_equal (iso_next_group_option" phrase in the search).

For this reason, I think it's upstream issue.

So looks like it's an upstream issue

Status changed to 'Confirmed' because the bug affects multiple users.
