Hello. Sorry for posting this many questions these days. Yet I have another one.
I have added export JAVA_HOME="/usr/java/java" to my etc/profile file, then rebooted. I opened a terminal under Gnome, typed env, but no JAVA_HOME! I then added the same line in /home/account_name/.bashrc and it worked. What am I missing?

JAVA_HOME and etc/profile
The profile files (/etc/profile, ~/.bash_profile) are sources upon 'logging in', thus, when a 'login shell' runs. The ~/.bashrc file is executed when a non-login shell starts. Since X terminal emulators are not login screens, they don't source the profile files. For some misterious reason, however, graphical login screens doesn't pass the enviromental variables in the profile files to spawned applications. That's why you don't get anything from profile when you use [xgk]dm. There may be a workaround, but I myself don't use any graphical login manager, so I can't help you with this. Put your settings to your .bashrc, or have your bashrc file source the /etc/profile file.
