Seems that 'at' mails you the stdout from the process, if nothing is
shown there try appending 2>&1 to the end of the command you are giving
to 'at' to see if stderr has any better diagnostic.

Maybe also the result of echo $PATH, echo $DISPLAY and so on from inside
the 'at' execution environment might help point the way.
