I have a similar problem. In my case, the first user after a reboot
gets permanent ownership of the device classes associated with
<console> in /etc/security/console.perms --- i.e. the devices in
<floppy>, <sound>, an so forth. After the first user logs out and
the next user logs in, all of the devices defined in the device
classes remain owned by the first user.
However, the owner of /dev/console, which is associated with
<xconsole> is reassigned properly.
Can anyone suggest why this is happening or how to get more useful
diagnostic information?
