I don't know how to "strace" (just in case stace is a term, as I am a bad English speaker).
strace is a command that shows you all the system calls of your application. You start it like this "strace <your app>". And your English is fine.
Thank you for enlighten me with 'strace'. I tried to strace the X applications and it turns out the reason is because I set locale to zh_CN.GB18030
Observing strace of xmessage(1), this line of message is printed repeatedly, which seems to be suggesting a locale problem.
read(3, "\1\0\212\0\0\0\0\0\0\0R\10\0\0\0\0H\343\355\277\33\277"..., 32) = 32 writev(3, [{"1\0\6\0\1\0\r\0", 8}, {"*-*-GB18030-0", 13}, {"\0\0\0", 3}], 3) = 24 read(3, 0xbfc36edc, 32) = -1 EAGAIN (Resource temporarily unavailable) select(4, [3], NULL, NULL, NULL) = 1 (in [3])
Switch to zh_CN.GB2312 and this problem is immediately solved.
output of strace is attached to this email.
Do you think I should file a bug? IMHO Linux should behave sanely when using zh_CN.GB18030 locale. GB18030 is the new encoding issued as Chinese mainland standard in 1999, while GB2312 is an old standard issued more then 20 years ago. Old standard GB2312 covers only 6,000 to 7,000 mostly-used Chinese ideographs, compare to a total number of 20,000 Chinese ideographs available today on modern computers. It is making good sense for SuSE to be compatible with the new standard (Though I think UTF-8 is much better choice).
Strange thing is, another computer which also suffer from this computer actually uses zh_CN.UTF-8 locale (same locale as the other two computer which do not suffer from this problem). See attachements
About AppArmor, I am afraid I have no knowledge on it but I can try if I can turn it off.
You can disable it in YaST2.
A discover: if I login as root, I can launch these applications very fast (as fast as on other Linux boxes), both in WindowMaker and FVWM. So it could be security-related. I'll see if I can find a clue and post results here.
That's interesting, but I can't really imagine why it behaves like that.
