lightdm writes continously to stdout/stderr

[James Hunt]

The soon-to-be introduced Upstart feature that allows job output to be logged has shown that lightdm is outputting a lot of data to stdout/stderr.

/etc/init/lightdm.conf currently just execs lightdm so a quick fix is to run instead:

  exec lightdm >/dev/null 2>&1

However, maybe lightdm should not be outputting such data by default?

Example of data:

[+23.89s] DEBUG: user-list.vala:1204: Drew 1 frames in 0.1 seconds (9.904717 fps)

This is a side-effect of the greeter output not being redirected to the correct log file. It should be fixed in the version going through SRU at the moment.

Hi Robert,

I'm still seeing this in oneiric with the current version in oneiric-proposed, 1.0.6-0ubuntu1.3. What particular version were you thinking it would be fixed in?

Thanks.

Actually, to clarify, I'm seeing this fill up the log file /var/log/lightdm/x-0-greeter.log.
