Here's my workaround that, once set up, requires no further intervention by the sysadmin (me) in our corporate environment:
In short, we are creating a shell script to kill all the remaining user processes after logging out of GNOME, setting that script suid root, and having gdm call that script upon log out. $ cat /usr/local/bin/kill-stragglers-auto #!/bin/bash # takes 1 argument: the username of the user who logged off USER=$1 sudo kill -9 $( ps U $USER | grep -v TTY | awk '{print $1}' ) 2> /tmp/kill-stragglers-auto.errors.log sudo /etc/init.d/gdm restart $ sudo chmod +s /usr/local/bin/kill-stragglers-auto $ ls -lh /usr/local/bin/kill-stragglers-auto -rwsr-sr-x 1 root root 213 Aug 27 18:32 /usr/local/bin/kill-stragglers-auto $ cd /etc/gdm/PostSession $ ls -lh total 8.0K -rwxr-xr-x 1 root root 395 Aug 27 18:30 Default -rwxr-xr-x 1 root root 305 Aug 27 18:29 Default.080827.orig $ tail Default fi done IFS=$OLD_IFS echo "$OUTPUT" } # the following was added by toobuntu on 080827: /usr/local/bin/kill-stragglers-auto ${USER} exit 0 Hope this helps someone! ** Changed in: gdm (Ubuntu) Sourcepackagename: xorg => gdm -- Processes remain after log off https://bugs.launchpad.net/bugs/236210 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
