Re: [Itifg-tech] need help configure shutter

[<M....@go...>]

Hallo,

so lets try to fix it...

At first I need mode debugging output. Please load the debugging
module (as root):

      rmmod itifg
      modprobe itifg_g

Then please run TWO acquisition cycle of Your program and send
me the output in /var/log/messages.

The interesting lines are those which contains 'itifg'. Please cut it,
because
the file is usually a bigger one.

Hope, the statements are right, because 7.2.1 is rather old...

                                    matthias
