Ubuntu comes with a disk space usage analyzer (GUI) called ‘Baobab’ (Gnome application). Other than displaying the disk space usage using pretty charts, it also used to include an option that lets you disable low disk space warnings, but there is no such option anymore in the version that is included in Ubuntu 14.10.
If you are an Ubuntu 14.10 user however, looking for a way to disable these disk space warning, luckily you can still do it through the ‘gsettings’ command-line utility or using the ‘Dconf-tools’ GUI.
If you just want to disable these warning, then it is probably easier to use the command-line method, but if you just need to change or tweak the settings (changing the default free disk space threshold to be considered before displaying these warnings for instance), then, although you still can use the command-line utility to achieve the desired goals, the GUI is more user friendly & easy to use.
*. If you just want to disable these warnings (for all partitions), then simply enter the below command through the terminal window:
gsettings set org.gnome.settings-daemon.plugins.housekeeping active false
*. If you want to re-enable the warnings, then use the below command:
gsettings set org.gnome.settings-daemon.plugins.housekeeping active true
*. However, if you want to manipulate some of its other settings as mentioned earlier, then for ease of use, install the GUI frond-end. You can use the below command for that:
sudo apt-get install dconf-tools
Once the installation finishes, search for it (‘dconf’) in ‘Dash’ and open it. Then from its menu select ‘Find…’ and search using the term ‘disk space’ as shown in the below screenshot.
This will open up the low disk space warnings related settings and through there you can change/tweak few of its individuals settings. That’s it!.
