Thanks for the response, Warren; sorry for the lateness of mine. Your
solution works when run from a shell, but devd still doesn't properly
execute it. I also tried changing the quotes around, adapting it for my
user shell (changing 'setenv' to 'export DISPLAY='), and putting it in a
shell script and executing the script from the devd config file. No
luck. Guess I'll just keep messing with it when the mood strikes, see if
anything clicks.
