This is just a minor annoyance, but I wondered if anyone has any insights.
When I first boot the system and log in to Gnome, and then plug in
e.g. a USB stick or compact flash card, I get an icon for it on the
desktop. I can right-click on this icon to "eject" the filesystem,
etc.
Eventually, though, for no obvious reason, this stops working and I no
longer get an icon when I insert a USB device. The automount is still
happening; I can still navigate to the device under /media with
Nautilus, and I can still umount it from a shell as a nonprivileged
user.
What process is supposed to be noticing the new mount and adding the
icon? Any clues as to why it would stop doing so?
