Configuration is exactly the same on the 18.04 and on the old 16.04. which,
it seems would be wrong.

Also note: There's still a comment on the HDPVR page on the wiki


"f you have the ir_kbd_i2c module loaded, this can cause the HD-PVR to hang
after a short amount of recording (60-120 seconds). Remove this module via
'rmmod ir_kbd_i2c' and try again if this is affecting you."

Every recording I've tried has hung after between 11 and 18 minutes with
the i2c driver loaded, so I'm quite concerned :-(

lircd.conf.d has the devinput conf file.  I've now renamed it to .dist.
 I'm not sure what to put in there for the HDPVR blaster.

# These are the default options to lircd, if installed as
# /etc/lirc/lirc_options.conf. See the lircd(8) and lircmd(8)
# manpages for info on the different options.
# Some tools including mode2 and irw uses values such as
# driver, device, plugindir and loglevel as fallback values
# in not defined elsewhere.

nodaemon        = False
driver          = devinput
device          = auto
output          = /var/run/lirc/lircd
pidfile         = /var/run/lirc/lircd.pid
plugindir       = /usr/lib/x86_64-linux-gnu/lirc/plugins
permission      = 666
allow-simulate  = No
repeat-max      = 600
#effective-user =
#listen         = [address:]port
#connect        = host[:port]
#loglevel       = 6
#release        = true
#release_suffix = _EVUP
#logfile        = ...
#driver-options = ...

uinput          = False
nodaemon        = False

# [modinit]
# code = /usr/sbin/modprobe lirc_serial
# code1 = /usr/bin/setfacl -m g:lirc:rw /dev/uinput
# code2 = ...

# [lircd-uinput]
# add-release-events = False
# release-timeout    = 200
# release-suffix     = _EVUP

I'll bet this is a problem...it still refers to zilog in hardware.conf.
Again, not sure what to change....

# /etc/lirc/hardware.conf
#Disable kernel support.
#Typically, lirc will disable in-kernel support for ir devices in order to
#handle them internally.  Set to false to prevent lirc from disabling this
#in-kernel support.

#Enable lircd

#Don't start lircmd even if there seems to be a good config file

#Try to load appropriate kernel modules

# Default configuration files for your hardware if any

#Forcing noninteractive reconfiguration
#If lirc is to be reconfigured by an external application
#that doesn't have a debconf frontend available, the noninteractive
#frontend can be invoked and set to parse REMOTE and TRANSMITTER
#It will then populate all other variables without any user input
#If you would like to configure lirc via standard methods, be sure
#to leave this set to "false"

#Chosen IR transmitter
TRANSMITTER_MODULES="lirc_dev lirc_zilog"

lircd.conf begins with this:

# contributed by Jens Leuschner <leuschner at gmx.net>
# brand:             Hauppauge
# model:
# supported devices: WinTV primo; WinTV pci; WinTV radio
# This config file will work with both homebrew receivers and
# original Hauppauge TV cards !!!

begin remote

  name          blaster
  bits          32

lircmd.conf has just comments.
