Hi,
Here is my thought on locale set up after default installation should
be. (This is with gdm 2.16.1-1)
Currently, default locale valure as installed on my system is:
LANG="en_US.UTF-8"
This was selected not to get in troble with Japanese characters under
console. That thought of UTF-8 itransition itself is good idea but it
is not simple.
I am wondering how best installer set up system.
Unless one is as expert as the installer team to set up console UTF-8
environment under non-X situation (i.e.,Linux console), you will likely
to get negative effect of screenfull of unreadable display if you are in
locale where characters not covered by ISO-8859-1 or similar. This
happens in places such as Japan, China, Russia, Thailand(I am guessing),
... (We do not set up UTF-8 framebuffer console as default by the
installer)
I think this is what we should expect under UTF-8 encoding:
Console and daemon should run under:
--> For en_* and all non-latain character countrues:
en_US.UTF-8
--> For non-english latain character countries may choose:
*.UTF-8 (Fr, De, It,...) but I think en_US.UTF-8 is OK too.
Then X applications should run under locale:
*.UTF-8
I see 2 critical files:
/etc/environment
/etc/default/locale
The use is kind of mixed.
And: from my "grep pam_env /etc/pam.d/*":
| atd:auth required pam_env.so
| cron:auth required pam_env.so
| gdm:auth required pam_env.so read_env=1
| gdm:auth required pam_env.so read_env=1 envfile=/etc/default/locale
| gdm-autologin:auth required pam_env.so read_env=1
| gdm-autologin:auth required pam_env.so read_env=1 envfile=/etc/default/locale
| login:session required pam_env.so readenv=1
| login:session required pam_env.so readenv=1 envfile=/etc/default/locale
| ssh:auth required pam_env.so # [1]
| ssh:auth required pam_env.so envfile=/etc/default/locale
| su:session required pam_env.so readenv=1
| su:session required pam_env.so readenv=1 envfile=/etc/default/locale
I think changing as following will help:
| atd:auth required pam_env.so
| cron:auth required pam_env.so
| gdm:auth required pam_env.so read_env=1
| gdm:auth required pam_env.so read_env=1 envfile=/etc/default/locale
| gdm-autologin:auth required pam_env.so read_env=1
| gdm-autologin:auth required pam_env.so read_env=1 envfile=/etc/default/locale
| login:session required pam_env.so readenv=1
| ssh:auth required pam_env.so # [1]
| ssh:# auth required pam_env.so envfile=/etc/default/locale
| su:session required pam_env.so readenv=1
/etc/environment LANG=en_US.UTF-8
/etc/default/locale LANG=ja_JP.UTF-8
This way we use /etc/default/locale for GDM while others use default
/etc/environment. (Thanks to recent bug #361090 fix which some people
oppose and reopened bug.)
For French etc, maybe both /etc/default/locale and /etc/environment can
be fr_FR.UTF-8 too.
This way, we ensure GDM talks the local language while X is run under
ones preffered locale set by GDM. At the same time, console, ssh and su
are run under barebone so vt-100 terminal will not be surprized by
Japanese characters. (SSH may bebetter to leave commented out line.)
I do not care the use of these 2 files are swapped as long as gdm is
started under *.utf-8 while console stays under en_US.utf-8.
