Debian uses a different name for the modprobe.conf file. You will have 
to google for it...Ubuntu is based on Debian and may have the same name 
as debian..

Otherwise, and in the meantime, put what you want to do in 
/etc/rc.local. That script file is run after all the other init stuff 
and just before the window manamger loads.

You DO need a line like lirc_imon, even if you are doing it as a 
'modprobe lirc_imon in rc.local. Otherwise lirc does not know which 
driver to use!

THe lirc docs are horribly obscure. They are exactly correct but have no 
context, so you cannot go back and do things again because you have not 
been told that some of the steps are (without other steps) irreversible.

You need:  a /dev/lirc (created by udev hopefully)
  an lircd deamon to be run as an init script (service)
an lircd.conf file which gives the raw keycodes and maps them to keys
an lircrc file which maps the keys to key commands in your programs.
some luck and remember to cross the third and fourth fingers of your 
*left* hand hehind you back...
