Problem description: When I install the “Chinese, China” facility in order to type Chinese, for a few days I can switch into Chinese using the default ctrl-space hotkey, but then it stops working, and the only way I can switch languages is to click on the icon in the status bar. Removing and reinstalling Chinese does not fix this bug.
Steps to reproduce:
1. Install Chinese, China, with default ctrl-space to activate Chinese
2. Do ctrl-space
Current behavior: nothhing hhappens
Expected behavior: entry of Chinese characters toggles on
Operating System: Linux (Other)
Version: 18.104.22.168 release
Could not reproduce on Ubuntu 14.04
You don't mention which exact Linux distribution you're using, but this sounds more like a distribution level issue than something specific to LibreOffice.
I have previously seen a similar issue where Chinese input has become confused when first installed - removing and reinstalling is not enough to cure this, you have to actually log out of the user session before it comes back.
I am using Linux Mint v. 17 Mate.
I have discovered that this is probably related to my use of a portrait-mode monitor (see below). When I set the screen to landscape mode and got rid of Chinese, rebooted, and reinstalled Chinese, I could use the default ctrl-space to toggle between Chinese and English (except that I have to do ctrl-space twice). When I reset the screen to portrait mode the toggle (ctrl-space twice) still works.
