Hi folks -
I just gave my 9-year old daughter a digital camera for her birthday, it comes
up as a usb storage class device and of course works fine.
The problem is I need to set it up suitable for a child to use on her laptop,
and the default situation of mounting and unmounting is very poor for that.
I did some reading and discovered autofs (there is a tip about it at
fedoranews.org), and was able to set this up with a timeout of two seconds,
and that works quite well. The autofs service is given a mountpoint and
dynamically mounts the given device at the mountpoint *when the mountpoint is
touched*. It then umounts the device after the timeout period.
I did some further reading and was able to also set up a hotplug script
specific to the camera IDs, which generates and deletes a symlink to the
mount point when the camera is inserted and removed.
That gets me a /mnt/camera link that appears when the camera is inserted, as
soon as you touch it, by ls /mnt/camera or anything else, the camera
filesystem is mounted, accessed (so in the ls example you see the camera
contents listed), and auto-umounted after the two second timeout period.
When you pull out the camera the /mnt/camera link is removed. That's really
nice.
But I want to go for gold and completely automate the process, such that
merely plugging in the camera moves all the files in the camera to a
specified directory and empties the camera. I can do this with the hotplug
shellscript using mv, but there is no feedback about the process and it is
critical the camera is not removed too early. What I want to use instead is
the KDE kfmclient move command, which brings up a nice dialog with a progress
bar that disappears at the end of the move action, same as a konqueror file
move. Then you need to wait three seconds, unplug the camera and you're
done. If this is possible I will write up a little howto bringing together
all the pieces.
The problem is that although I can run a test kfmclient instance as root which
works...
[root@fastcat root]# kfmclient move /mnt/camera/* '/home/agreen/pics'
this does not work when running from the hotplug script, presumably because
that shell lacks some critical authentication or other information needed to
allow X to accept it. (Confession: I try this on an FC2 devel machine, but
the question is relevant for all FC versions).
I looked around some more late last night, and saw that gPhoto2 has a script
for this situation which should be able to run an X11 app from a hotplug
script, called usbcam.x11-app. The business end of that boils down to
su -l agreen -c "env DISPLAY=:0 HOME=/home/agreen kfmclient copy /mnt/camera/*
'/home/agreen/Pics'"
trying this out gets me
Would you like to enter a security context? [y] n
bash: /root/.bashrc: Permission denied
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
kfmclient: cannot connect to X server :0
My question is then: how can I spawn an X app, preferably with user
credentials rather than root, from a hotplug script.
