Disabling GNOME Tracker and Other Info
GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/
After discovering it chowing 2 cores, I decided to go about disabling it.
After wiping and letting it do a fresh index on my almost new desktop, the total size of each of these directories was a whopping 3.9 GB!
On my Ubuntu GNOME setup, I found the following files:
$ ls /etc/xdg/autostart/tracker-* /etc/xdg/autostart/tracker-extract.desktop /etc/xdg/autostart/tracker-miner-fs.desktop /etc/xdg/autostart/tracker-store.desktop /etc/xdg/autostart/tracker-miner-apps.desktop /etc/xdg/autostart/tracker-miner-user-guides.desktop
You can disable these by adding
Hidden=true to them. It's best done in your
.config directory because 1) you don't need sudo and 2) you are pretty
much guaranteed that your changes won't be blown away by an update.
tracker will give you a vast array of tools to check on tracker and
manage its processes.
$ tracker usage: tracker [--version] [--help] <command> [<args>] Available tracker commands are: daemon Start, stop, pause and list processes responsible for indexing content info Show information known about local files or items indexed index Backup, restore, import and (re)index by MIME type or file name reset Reset or remove index and revert configurations to defaults search Search for content indexed or show content by type sparql Query and update the index using SPARQL or search, list and tree the ontology sql Query the database at the lowest level using SQL status Show the indexing progress, content statistics and index state tag Create, list or delete tags for indexed content See 'tracker help <command>' to read about a specific subcommand.
Non-Invasive Disable Cheat Sheet
This disables everything but
tracker-store, which even though it has a
.desktop file, seems tenacious and starts up anyway. However, nothing gets
tracker daemon -t cd ~/.config/autostart cp -v /etc/xdg/autostart/tracker-* ./ for FILE in `ls`; do echo Hidden=true >> $FILE; done rm -rf ~/.cache/tracker ~/.local/share/tracker
tracker daemon -t is for graceful termination. If you are having
issues terminating processes or just want to take your frustration out,
tracker daemon -k immediately kills all processes.
After this is done,
tracker-store will still start on the next boot. However,
nothing will be indexed. Your disk and CPU will be better for wear.
$ tracker status Currently indexed: 0 files, 0 folders Remaining space on database partition: 123 GB (78.9%) All data miners are idle, indexing complete
