In previous versions of Ubuntu, I used a calculator scope from some PPA. It was very nice, worked snappily and generally behaved like calc.
13.10 has it's own calculator, which can be used, but it stopped working after I disabled web results with unity tweak tool. Even when it was working, it was sluggish, as if it only used the calculator if it found nothing else anywhere.
I can still use the calculator by typing
calculator:1+1
or enabling it from the filter results -menu.
But those options defeat the purpose.
How do I enable the calculator scope to always be triggered by default?
unity-scope-calculator
. To enable it for the current user session, go to 'Filter Results ↓', and click 'Info' or 'Calculator'. A better way to disable online results, look in the Security/Privacy settings. There is this: askubuntu.com/questions/202944/… as well, which sort of means you might not be able to enable the calc as default...
