'LeftShift+RightShift' switches layout although it's not configured to
I have a new Ubuntu 18.04 with Gnome 3.28.1 installed on my laptop, and I run into a problem.
I have set Alt+Shift
on keyboard layout switching, but LeftShift+RightShift
combo also triggers the switching, and I just can't find out why.
I have used gnome-tweak-tool
for the configuring, and I can guarantee that there is no ticks on the checkbox Both Shifts together
. As for built-in Settings -> Devices -> Keyboard -> Typing
, they have been set to Disabled
and therefore can't interfere.
Also, I checked org/gnome/desktop/input-sources
via dconf-editor
, and it shows grp:alt_shift_toggle
as it should, there is no mention of grp:shifts_toggle
at all. But it still switches a layout, and it just makes me mad.
However, if I disable Alt-Shift
as a layout-switcher, LeftShift+RightShift
also disappears, so it seems grp:shifts_toggle
is a sort of "backup value" or "repeater" of grp:alt_shift_toggle
.
There are some links where people had encountered with the same, but no solution was found.
