Comment 1 Peng Wu 2011-06-10 04:55:05 UTC

Which command do you use when switching to root user?
`su` or `su -`?

Comment 2 Kenichi Takemura 2011-06-10 04:58:14 UTC

I use 'su -'

Comment 3 Peng Wu 2011-06-10 05:39:15 UTC

Please use `su` instead, `su -` will clear up some environment variables which are needed for scim.

Comment 4 Kenichi Takemura 2011-06-10 06:10:07 UTC

Ok. 'su' works for me.

Then Summary of this bug should read 'Cannot trigger input method(skim) when switching to root with -'?

Comment 5 Peng Wu 2011-06-10 06:26:02 UTC

Ok. Thanks for the report. Close this bug.

Comment 6 Kenichi Takemura 2011-06-14 00:00:16 UTC

Hi I have a question.

In zhCN I can trigger scim after 'su -', why?

Comment 7 Peng Wu 2011-06-14 08:27:39 UTC

Sorry, I make a mistake. Re-open it.

Comment 8 Peng Wu 2011-06-16 04:30:57 UTC

I finally re-produced this on RHEL 5.7 beta.

To re-produce this bug, need to change the locale of the root user.

Re-produce steps:
Method 1:
1. change the locale in /etc/sysconfig/i18n, then reboot;
2. this bug happens with ko, ja. IME works in zh_CN.

Method 2:
1. switch to root user with `su -`;
2. launch gedit with `LC_ALL=zh_CN.UTF-8 LANG=zh_CN.UTF-8 gedit`;
3. this bug happens with ko, ja. IME works in zh_CN.

Comment 9 Jens Petersen 2011-08-02 06:32:31 UTC

BTW skim actually exists (it was scim for KDE) so better not to misspell it.

While this is an interesting report - not really sure if
it is worth an errata.  It is not really recommended to
run GUI applications as root.

eg I just tried running system-config-users on F15 and RHEL6
for example and also can't use IM there for better or worse.
