Ubuntu 16.04 input language switching stop working after couple switches (two, three times) I've tried reinstalling language-support,tried reinstall ibus, maybe there is a way i can reinstall language-switcher ?
I found the problem. I runned
htop and found that gnome-settings-daemon uses 99% CPU. Than i found this answer https://askubuntu.com/a/809810/640672 and it helped.
