gnome-tweak-tool 3.10.1-0 fails to launch in Ubuntu and Edubuntu

[Erick Brunzell]

I'm testing gnome 3.10 packages from the gnome 3 PPA and I notice that the latest version of gnome-tweak-tool fails to launch if used in Ubuntu or Edubuntu. Trying to launch from terminal says this:

WARNING : Shell not installed or running

    default = self.STATUS.keys()[self.STATUS.values().index(self.settings[self.key_name])]
ValueError: None is not in list

It had worked in Ubuntu and Edubuntu even w/o gnome-shell being installed since Quantal and it can be quite useful in flashback mode.

The new version works perfectly in Ubuntu GNOME.

Hi Lance,
  Can you file this upstream as well on bugzilla.gnome.org

[Erick Brunzell (lbsolost)]

I had to create an account ............ first bugzilla bug ever so I hope I did OK:

I've installed gnome-tweak-tool (version 3.10.1-0ubuntu1) from ppa:gnome3-team/gnome3 repo on Ubuntu 14.04 and got this error in terminal when tried to launch unter Unity Desktop Shell:

I just uploaded a fix to gnome3/trusty PPA. Please test and let me know if there are any other bugs, I plan to upload into Trusty proper soon

[Erick Brunzell (lbsolost)]

Looks good here. In Ubuntu GNOME Trusty I tested the new build in the standard gnome shell, gnome classic, and flashback w/metacity sessions.

Then in Ubuntu I tested the new package in the standard Unity, flashback w/metacity, and flashback w/compiz sessions.

No problem at all but I suppose one could argue that 'gnome-tweak-tool' is not the optimal tool for tweaking Unity???

I did encounter an unrelated problem while testing Unity - if the key sequence for killing X is changed then the logout button does not seem to respond properly. There is no difference in which version of 'gnome-tweak-tool' is used to change that sequence though. I'll follow up on that ASAP.

[Erick Brunzell (lbsolost)]

I ruled out 'gnome-tweak-tool' (or any component of 'gnome-shell' or 'gnome-session-flashback') being related to that problem with Unity not logging out properly after editing the key sequence for killing X by performing a fresh install of Ubuntu Trusty and only installing 'dconf-tools' and then editing the sequence in "org.gnome.desktop.input-sources". Unity just doesn't like to be tweaked in some ways I guess, but this new package should be OK to upload to proposed.

[Tim Lunn (darkxst)]

thanks for the thorough testing!

the other issue sounds like its a bug in gnome-settings-daemon, file a bug there for that one.

[Erick Brunzell (lbsolost)]

@ Tim, I probably won't get around to that until after 12.04.4 is released next Thursday.

But I can assure you that 'gnome-tweak-tool' is in no way involved.

[Erick Brunzell (lbsolost)]

The problem mentioned in comment #7 finally made it to the top of my to-do list but I can no longer reproduce the issue so no need to file a new bug report ATM :^)
