Thanks for taking an interest in my problem, I really hope you can shed
some light on it for me. Before upgrading to 12.04 this system was rock
solid and the remote control worked perfectly. I'm almost tempted to roll
back to version 11.
When I posted this I removed lirc due to the issues I was experienced. As
you very kindly replied I reinstalled it. As usual it was working fine in
that I could get irw working and recognising keypresses. Then as usual
after several reboots it suddenly stops working with the usual symptoms of
hanging whenever I try to do anything with lirc or try and shutdown the
machine. I've tried as best to answer your questions. Usually to test
lirc works I type:
sudo /usr/sbin/lircd -H dev/input -d /dev/input/event6 -n
*
*
In one window and the irw in another so the hardware.conf might not be
completely correct.
