That depends on whenever you'll execute this script from an X client or not. Stopping xdm would terminate X, which, in turn, will terminate all X clients, which, in turn can prevent xdm from starting.

unmount a removable store automatically before xdm logout.
~/MP is the mount point for a removable store which contains sentinel Mounted. ~$ mount | grep MP /dev/sda1 on /home/peter/MP type ext2 (rw,nosuid,nodev,relatime,errors=continue,user_xattr,acl,user=peter) peter@dalton:~$ ls -l MP/Mounted -rw-rw-r-- 1 peter peter 11 May 25 15:45 MP/Mounted This is the draft logout script. ~$ cat mylogout cd /home/peter if [ -e MP/Mounted ]; then if [ "$(command lsof -Fn MP)" ]; then # Files are open. Abort logout to allow resolution. exit 1 ELSE umount /home/peter/MP # sudo is configured to allow this w/o a password. nohup sudo /etc/init.d/xdm restart >/tmp/xdm.restart 2>&1 & fi fi exit 0 Not sure that "xdm restart" should run in the background. Any comment welcome. Thanks, ...
