Diodon not working on Ubuntu 15.04

Quickly tested myself and it seems that Diodon is suffering the issue Bug 1435033 on Ubuntu 15.04 as well. This only happens the very first time Diodon starts though after installation so if you close Diodon and open it again it should start working.

Hi Oliver, thank you for the reply.

I have restarted Diodon (through the GUI) but it is still not capturing the strings copied to the clipboard. Should I try a restart some other way?

Thank you.

It might be a configuration issue then see here https://esite.ch/2014/08/why-does-diodon-not-save-anything-to-the-clipboard-history/

Is that the case?

Hi again Oliver,

I have Zeitgeist on, I only disabled it for chat logs.

Btw, I now have CopyQ functioning without issue, so the clipboard seems to be accessible.

Regards.

I have checked again on a fresh 15.04 installation and when Diodon is started the second time it works as always.

There has to be something else on your machine then.

To figure this out can you close Diodon and also CopyQ (two clipboard managers at the same time might cause issues) and run the following:
G_MESSAGES_DEBUG=all diodon > diodon_debug.log

Then copy something to the clipboard and check whether history is empty. If it is please paste the content of diodon_debug.log here so I can better analyze.

I have done this debugging step. I attempted to copy the URL of this bug report. It appears to copy, but never shows up in Diodon. I have closed and opened Diodon multiple times, but still no clipboard entries ever appear in the dropdown menu.

Here is the output:

I should have added I also am on Ubuntu 15.04, latest updates.

Seems Diodon works as expected but the Zeitgeist backend doesn't record anything.

Can you double check whether following settings is set to true:
gsettings get org.gnome.desktop.privacy remember-recent-files

and if not needs to change to true.

Also if this is set to true resetting the Zeitgeist database might help - you can do this by first closing Diodon and then run the following commands:
mv ~/.local/share/zeitgeist/ ~/.local/share/zeitgeist-old
zeitgeist-daemon --replace

Let me know if one of those steps is successful.

Indeed, that setting was false. After following both steps and then restarting Diodon twice, I am able to see clipboard history! I am not sure if the second step is necessary since I followed both before testing.

OK great. I assume the first step would have been enough if it was false in the first place.

Is this then a bug with the default Gnome settings in Ubuntu 15.04, or is this a problem with how Zeitgeist interfaces with Gnome? I don't want Gnome remembering my recent files if possible - I just want to copy clipboard contents.

The name of the option is a bit confusing as it mainly talks about enabling recording of activities within Gnome and also Unity. This can then be filtered what you want to record in the Privacy dialog.

Unfortunately recording of recently used documents and clipboard are currently the same option (checkbox Documents) - you can find more details about this in Bug #1312704 where we want to change this. The rest of the recording can be disabled though.

If you are really concerned about privacy can you also run Zeitgeist completely in memory.

You can do this by setting following env var (e.g. adding it to ~/.pam_environment):
ZEITGEIST_DATABASE_PATH=:memory:

You will need to logout and login again that the env var will be set properly.

Ok, so the GUI solution in Ubuntu 15.04 is (for the sake of others having this problem):

* Open Security & Privacy app -> Files & Applications tab.
* Enable 'Record file and application usage'.
* Check the box next to 'Documents' - all other boxes can be left unchecked if you desire privacy.

Hopefully Oliver's Zeitgeist patch will be accepted and the next version of Ubuntu will separate clipboard privacy from documents.

Until this is fixed, maybe a warning could pop up if Diodin detects that the Gnome privacy setting is set to false?
