- When executing "sux - some_user" and then printing the environment with "env" you will notice that none of the x DISPLAY variables have carried over.
- When executing "su - some_user" and then printing the environment with "env" you will notice that none of the x DISPLAY variables have carried over.
- When executing "su -" or "sux -" (which implies the root user) and then printing the environment with "env" you will notice that the x DISPLAY variables have carried over.
The man page for pam_xauth tells the details
In order to have the functionality your used to in Pre SLE10 days then you will need to do the following:
Change /etc/pam.d/su to have
session optional pam_xauth.so systemuser=1
Once you make that change you will be able to execute scenario's 1 and 2 without a problem and it will carry over the x DISPLAY variables.
You can also execute "su some_user" without the "-" and that will work as well.
Specify the highest UID which will be assumed to belong to a "system" user. pam_xauth will refuse to forward credentials to users with UID less than or equal to this number, except for root and the "targetuser", if specified.
