Description Alexandre Rostovtsev 2012-09-27 22:01:30 UTC 
Running desktop-file-utils from desktop-file-utils-0.20 on .desktop files with "AutostartCondition=GNOME3" results in an error:

$ desktop-file-validate /etc/xdg/autostart/bluetooth-applet.desktop
/etc/xdg/autostart/bluetooth-applet.desktop: error: value "GNOME3 if-session gnome-fallback" for key "AutostartCondition" in group "Desktop Entry" contains an unregistered value "GNOME3" for the condition; values extending the format should start with "X-"

This is because according to the autostart spec, the condition needs to start with a desktop environment name registered for use in "OnlyShowIn" - e.g. "GNOME", "KDE", "Unity", etc.; and "GNOME3" is not on the list.

Possible solutions:
1. Use "X-GNOME3" instead of "GNOME3"; or
2. Add "GNOME3" to the list of desktop environments registered for "OnlyShowIn"; or
3. Amend the autostart spec to use a separate lists of registered desktop environments for "AutostartCondition" and "OnlyShowIn".

Do you have a link to the autostart spec that specifies AutostartCondition ?
Comment 2 Alexandre Rostovtsev 2012-09-29 21:57:28 UTC 
Original spec proposal, before it was renamed from Autostart-Condition to AutostartCondition:
http://lists.freedesktop.org/archives/xdg/2007-January/007436.html

Implementation in desktop-file-utils ("Autostart spec, currently proposed; adopted by GNOME"):

Comment 3 Matthias Clasen 2012-09-30 23:41:36 UTC 
Right, so as that commit says, it never really made it to the actual spec here: 
http://standards.freedesktop.org/autostart-spec/autostart-spec-latest.html
The implementation has evolved over time; I would say it is best to simply accept the fact that GNOME3 is now in use as a condition.

(In reply to comment #3)
Fair enough; I've filed a bug with desktop-file-utils maintainers, let's see what they think of it:
