<div>I presume you have googled this?

However I deduced from your suggestion that there must be some nuggets of useful information there so looked in more detail and did find the suggested workaround of preceding the command with</div><div><br></div><div>if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then<br> eval `dbus-launch --sh-syntax`<br>fi</div><div><br></div><div>However I then intermittently got an error that it could not write to the file ~/.cache/dbus/user which I worked around by changing the ownership on that file to myself (from root). Whether that situation will re-occur I don't know, the bug reports I followed about that issue did not obviously come to any conclusion as far as I can see.

I am using tracker [1] and trying to run<br>

tracker reset -f ~/<br>

However, I am running it in a situation where there is no display<br>

Tracker-WARNING **: Failed to load SPARQL backend: Cannot autolaunch<br>

Is there some magic I can perform to allow this to work?<br>
