i am trying to run x programs as root under a normal user's X-session. i get the following.
| Code: | xterm
Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted

program as a non-root user or by removing the suid bit on the executable.
xterm Xt error: Can't open display: %s
xterm: DISPLAY is not set |
when i am su into root and the same when i sudo xterm
| Code: | sudo xterm
Warning: This program is an suid-root program or is being run by the root user.

| Code: |
xhost +
xhost +localhost
|

It's probably your DISPLAY environment variable. Do echo $DISPLAY as your
normal user and then export that output as root
eg:
| Code: |
export DISPLAY=":0.0"
|
That should do it, along with the xhost stuff...

the problem was that i used
instead of
| Code: |
export DISPLAY=":0.0"
|
although i still get an error if i using the following set up, which i think should work.
| Code: |
> xhost -
access control enabled, only authorized clients can connect
> xhost +localhost
localhost being added to access control list
> sudo su
dong alex # echo $DISPLAY
localhost:0.0
dong alex # xterm

See this thread.
Or this one.
or this one,
or this one (which also mentions why sudo su is wrong),
or this one,
or even this....
