I am writing a quick script to read user input and put into commands of a couple different programs. I'm using xterm -e to open a terminal for each separate program.
The script is working fine, but each time xterm -e is executed, an error message is displayed:
Warning: Tried to connect to session manager, None of the authentication protocols specified are supported
Any ideas on how to stop this from displaying?
xterm uses the $SESSION_MANAGER environment variable to find out how to contact the X session manager.
In your case it seems to be unable to authenticate to it. Possibly, that script is started in the current session but as a different user.
Anyway, you don't have to report to a session manager so you can as well unset that variable to make the error message go away:
unset -v SESSION_MANAGER
In POSIX-like shells (or unsetenv SESSION_MANAGER in (t)csh or set -e SESSION_MANAGER in fish)
Or if your env supports the non-standard -u option, start xterm as:
env -u SESSION_MANAGER xterm ...
Actually, xterm does not directly use the SESSION_MANAGER variable. That is used in the Xt and SM libraries.
A more direct method of disabling the session manager feature is found in the xterm manual, first in command-line options:
-smThis option, corresponding to thesessionMgtresource, indicates that xterm should set up session manager callbacks.
+smThis option indicates that xterm should not set up session manager callbacks.
and then in application resources:
sessionMgt(classSessionMgt)
If the value of this resource is "true", xterm sets up session manager callbacks forXtNdieCallbackandXtNsaveCallback. The default is "true".
Since these features were introduced in patch #169 (2002), it is likely that they are available.
You can ignore it with:
xterm -e 2> /dev/null
