Ubuntu warns me about low disk space even when there are about 2 GiBs free. For me "low disk space" is 50 MiB or less as I use to use my disks at 100% capacity. The warning could be useful for me if it was warning only when I am really running nearly OUT of space. Can this be configured?

The notification is part of the gnome-settings-daemon, you can change its behaviour in gconf-editor. To do so:

  1. Press Alt + F2 and enter gconf-editor
  2. Go to apps > gnome_settings_daemon > plugins > housekeeping
  3. Change free_size_gb_no_notify to 0.05 (for ~50MB) or whatever you'd prefer.

There is also a bunch of other settings in there you may find helpful.

Unfortunately it only accepts integer values, so I can't set it 0.05 - only 1 GB at least. – Ivan Nov 5 '10 at 21:31

If you create the key of type 'Float', you will be able to specify a value of 0.1 (100MB). I was unable to enter lower value, because of the precision limited to 1 decimal digit
