I have deepin 20.8.
I can't change keyboard layouts from eng to gr over the viber.
so I can't send messages in Greek
oh deer friend,
most of time, you could press "ctrl" and "space" at the same time in order to change the language .
and we need to know if that situation happens on other softwares.
I have this problem only with viber software.
I press ctrl-shift and nothing happen.
The English language stays in the viber text line and in the taskbar.
