Re: SCIM and pinyin prediction - how do I turn it off?
I'm not sure what is causing your scim-pinyin to behave like that. On my system, when I type "wo" I still see 我 as the first character in the list.
You could check the settings of the buttons on the small panel at the bottom of the screen. There are two buttons between the 智能拼音 label and the 'moon' symbol. The default settings are 全 and 中. If they are set to something else, this could be causing problems.
If you want a more simple pinyin without prediction, then you could install scim-m17n and use either "zh-py" or "zh-tonepy". The latter requires you to type in the tone number before any characters become visible.
BACKUPS are unsexy — until you discover you should have done one yesterday.
Spare your nerves and do one before you upgrade or install.
