[Bug 1768291] Re: lirc is flooding the syslog with two lines each second

 

This problem also affects me. I am running Ubuntu 18.04 LTS with MythTV, and I sometimes plug in a remote control USB. When it's not plugged in, LIRC spams the syslog. I tried to disable startup of lircd daemon but that didn't seem to work. 
   sudo systemctl disable lircd.service
   sudo systemctl disable lircd.socket
and this appeared to set the links in /etc/rc2.d to be "K*lircd (kill) ) but
the glob spamming still occurred after the next reboot.

  This is not only annoying as it makes it difficult to use the syslog
  for checking the system, but also it writes too much data into the log
  (18MB each day). Also it keeps the hard disc awaken what is bad for
  standby.

  Kubuntu 18.04
  ii  liblirc-client0:amd64 0.10.0-2     amd64        infra-red remote control support - client library
  ii  liblirc0:amd64        0.10.0-2     amd64        Infra-red remote control support - Run-time libraries
  ii  lirc                  0.10.0-2     amd64        Infra-red remote control support - daemons and utils

  I do not have infrared remote control hardware. But I cannot purge the
  packages as other packages I want to keep would be removed as well.
  Deactivating the services in systemd does not help (or I am doing
  something wrong?)

  Gert
