I just installed ubuntu 12.10 and gnome 3, I opened gcalctool and there is no way to change the base and the calc type. Am I right or it's just my stupidity?

Here is a screenshot of it:

What happens when you try to change the mode from menu? – devav2 Oct 23 '12 at 9:56
there is no menu – Frederico Schardong Oct 23 '12 at 23:27
I am using GNOME Shell 3.6.2 – Frederico Schardong Mar 17 '13 at 20:21
It shouldn't help much, but still... In Unity, you do not see the menu attached with the calculator itself. Its present at the top. See the screenshot: Is it same with Gnome - Do you manage to find the menu bar? – Aditya Mar 17 '13 at 20:28
It is not the same with Gnome, each application holds its menu – Frederico Schardong Mar 17 '13 at 20:30

You can change the Calculator mode through the menu. You do not see the menu attached with the calculator itself, its present at the top panel. See the screenshot:


To change the base, you would need to use the Programming mode:

Bring up the calculator, then left click on the icon of the calculator in the upper left hand corner of the tool bar. A drop down menu will appear where you can select the mode.

I had the same problem. The only way that I managed to solve that problem was changing the key Exec in /usr/share/applications/gcalctool.desktop from



Exec:gksu gcalctool

There is a nasty consequence: you have to enter the root password every time that you want to open the calculator.
