calculator does not start using special-key on keyboard

[Tom Lü]

Hi,

just installed 18.04 on my desktop.

Using the calculator-special-key on my keyboard calculator does not start. :(
Using the menu the calc just starts as expected.

Looking for an error in gnome-logs, I found this one:

gsd-media-keys
Could not find application 'org.gnome.Calculator.desktop' or 'gnome-calculator.desktop'

Further investigation:
Since 18.04 calc is installed as a snap.
Looks like my special-key tries to start calc, but does not success due to an error in linking to the snap-system.

As a workaround I installed the package gnome-calculator:
sudo apt-get install gnome-calculator

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks @mottenkiller.

I've marked my bug, https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1773589, as a duplicate of yours since you actually uncovered the mechanics of the problem.

Thx @ckrainey

Maybe the problem is attached to media-keys plugin of gsd:

settings - devices - keyboard - launchers - launch calculator
--> (in this case) falsely using command 'org.gnome.Calculator.desktop' or 'gnome-calculator.desktop'

Using a custom shortcut with command 'gnome-calculator' works as a charm.
Even if I remove package gnome-calculator; with only snap gnome-calculator installed. ;-)

Imo this should be the solution.

So if I am right and I understood the sources without any errors, simply adding 'gnome-calculator' to line 2437 in 'gsd-media-keys-manager.c' should fix the bug:

 do_execute_desktop_or_desktop (manager, "org.gnome.Calculator.desktop", "gnome-calculator.desktop", "gnome-calculator", timestamp);
