How to show date on task bar on Trisquel 7.0?

I don't see an option to do this with the Indicator Applet (which Trisquel 7 uses by default), but one possibility is to use the Clock Applet instead (add it to the panel by right-clicking on an empty space and choosing "Add to panel...", then choosing "Clocks"). If you do this, you may also want to use the Notification Area applet to replace the Indicator Applet's notification area, unless you want to have two clocks showing at once. :)

This solution is compatible with indicator-applet
to activate:

$ dconf write /com/canonical/indicator/datetime/show-date 'true'
$ dconf write /com/canonical/indicator/datetime/show-year 'true'

Deactivate:

$ dconf write /com/canonical/indicator/datetime/show-date 'false'
$ dconf write /com/canonical/indicator/datetime/show-year 'false'

Wow, thank you for that. I have no idea how normal users are expected to know that.

Me neither mr bchurchwell.

There are more options, try to download dconf-editor, execute it and explore the options. You didn't think that there were so many (me neither until I read the gnome-manual).

Cheers
