I'm using PyCharm and sometimes the keyboard stops working because of iBus. The latest versions of PyCharm have a warning message recommending use of iBus 1.5.11 or newer.
1) How can I check the version of iBus?
2) How can I update iBus?
3) Can I safely remove iBus if I write in Dutch, Spanish and English (sometimes German)?
1) Checking the version of IBus is simple
ibus version
