i can confirm that this problem occurs in lucid version of distributions
Kubuntu and Xubuntu.
it really sucks.
to make it better:
the relevant line 8 of /etc/cron.weekly/apt-xapian-index is (where $CMD is
update-apt-xapian-index ):
nice ionice -c3 $CMD --quiet
we can have much more than this:
- give a nice level of 19 instead of default 10
- enter a missing space so ionice will do its job
- make the indexer update only NEW packages instead of the whole database (as
suggested by MarcS in comment 31)
this will get the most silence without dropping the indexer altogether:
- tested that the indexer will silently exit if database is already built
- tested that a 800mhz/256mb xcfe box stays responsive while indexing with the
new nice/ionice pattern
which fixes this issue for me.
