Two of my computers running Ubuntu randomly ignore the configured keyboard layout and fall back to qwerty.

On one computer the configured layout is "Français" (French), on the other it is a bépo (dvorak-like layout for French). On both computers the layout was selected at installation time in order to make it the default system-wide. On both computers the login screen always uses the right layout. It's only once that the user is logged in that the keyboard starts working as a qwerty

One computer uses LightDM and Unity, the other uses GNOME Display Manager and GNOME 3.8. The problem occurred with Ubuntu 14.04 and is still in 14.10.

So far I tried to erase my ~/.gnome* and ~/.config directories and to reinstall the system, without success. I have also ensured that the session settings were copied in the system settings in the control panel.

Do you have any hint to solve this problem?

Edit: also, even if the layout is incorrect in the session, it is still correct in a terminal opened with ctrl+alt+F1.

I have installed trac on my server running Ubuntu 12.04. The problem is that the users cannot change the language in their preferences. Instead, the following message is displayed:

Translations are currently unavailable. Trac has been localized to more than a dozen of languages but in order to be able to use them, the Babel package needs to be present when installing Trac. See TracInstall for details.

The installation has been done using the repositories of Ubuntu, but I could not find any package related to trac and babel, nor trac and anything related to internationalization.

How can I install the translations for trac?

I have a shell script "the_script" that I would like to register as the default application for the files with the extension ".ext". For this purpose, I have written an xml file to register the mime type, and a .desktop file to associate the application with the mime type. The script has the executable bit for the user and is available in the user's path.

The xml file, named "the_script.xml" is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
    <mime-type type="application/x-the-script">
        <comment>A file for the script</comment>
        <glob pattern="*.ext"/>
    </mime-type>
</mime-info>

Then I ran xdg-mime install --novendor the_script.xml.

The .desktop file, named "the_script.desktop" is as follows:

[Desktop Entry]
Version=1.0

Type=Application
MimeType=application/x-the-script

Name=The script that manages .ext files

Comment=Interpreter for .ext files

TryExec=the_script
Exec=the_script %f
Terminal=false

And I ran xdg-desktop-menu install --novendor the_script.desktop to register the file.

Once that both files are registered, the .ext files do not open with the text editor any more but Gnome tells me that there is no installed application for the files "A file for the script".

I have successfully registered other file formats with other applications. The other applications were compiled programs while the_script is a shell script. That is the only difference I can see. How can I register my script with the .ext files?
