lightdm writing the same DEBUG message to /var/log/lightdm/lightdm.log

[Colin Ian King]

I was trying to figure out where excessive file system writes were
coming from on the ubuntu phone (to try to reduce flash writes and hence reduce power
consumption) and I spotted that /var/log/lightdm/lightdm.log is getting the same debug message written to every every 300 seconds:

tail -f /var/log/lightdm/lightdm.log
[+5109.66s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+5409.67s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+5709.66s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+6009.66s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+6309.64s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+6609.65s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+6909.67s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+7209.66s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+7509.66s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+7809.57s] DEBUG: User /org/freedesktop/Accounts/User32011 changed
[+8109.65s] DEBUG: User /org/freedesktop/Accounts/User32011 changed

while this isn't much of a message, it still is causing file system writes every 5 minutes for the same debug message. Is this necessary? The fact that it is the same message about the same account and that it occurs every 300 seconds make me wonder if we can cull this particular piece of repeated logging.
