Re: Question on Ubuntu pinyin input
When I use pinyin (not often, admittedly) I use sunpinyin with the iBus input engine.
There is also a "pinyin" input for iBus, but it's been a while since I did any pinyin input, so I don't recall what the difference is.
iBus is the default input engine for 16.04, so unless you've done something unusual, you probably already have it installed.
BACKUPS are unsexy — until you discover you should have done one yesterday.
Spare your nerves and do one before you upgrade or install.
