Re: GNU emacs locks files modified with CVS

[gebser]

There's two ways which will keep/set the DISPLAY variable:

First, if the DISPLAY variable is set in user1 and you do "su user2", 
then the environment of user1 will carry into user2.  IOW, you're good. 

Second, if you, instead, do "su - user2", then you will have a fresh 
environment, that of user2.  If user2's environment doesn't have the 
DISPLAY variable set properly, you can do this by setting this in 
user2's ~/.bashrc file... if user2's default shell is bash-- if you're 
using some other shell, consult the manpage for the proper file and 
command syntax for setting the environment.
