Caffeine doesn't work on Xubuntu 14.04

[Benitron]

Hello, first thanks for what you do for the community !

I installed Caffeine on Xubuntu 14.04 (with terminal) :
$ sudo add-apt-repository ppa:caffeine-developers/ppa
$ sudo apt-get update
$ sudo apt-get install caffeine

I can not see it in the "Whisker Menu" and tried also to see it in "the old one", but nothing. Furthermore, I cannot launch the preferences anymore.
(I even tried to reboot the computer to see it it was due to the menu)

I can launch Caffeine with a terminal and an icon appears on the "Desktop toolbar" (sorry, I don't kwnow the name in English). From there, I can click on "Disable screensaver", but it doesn't work.
Also, not to be able to go to the preferences to use the "autostart on login" and chosse the softwares is disturbing.

So, is there a way to launch the "Caffeine preferences panel" (even with a terminal)
Is it a known bug ?

Maybe Xubuntu is not supported by Caffeine anyumore ?

Have a nice day !

Ben

I'm venturing a guess that it has something to do with Xubuntu switching to LightLocker and moving away from Xscreensaver.

Here are the errors I get with 2.6.2 I have lightlocker disabled and xscreensaver installed.

Did all the same and get the same results as Ben and Raymond.

[Bryan Jensen (5-launchpad-r)]

this one works: https://launchpadlibrarian.net/159439047/caffeine_2.5_all.deb

[Benitron (benlarcher-1)]

As for me, https://launchpadlibrarian.net/159439047/caffeine_2.5_all.deb doesn't seem to work...

To overcome it, I have created a launcher (with light-locker-settings) on the desktop and draged it to the upper toolbar.

Have a nice day !

There are no preferences in Caffeine 2.6 and later. To autostart Caffeine on login, use your desktop's startup application configuration system (e.g. gnome-session-properties in GNOME).

Caffeine 2.6 only works with a few screensavers that implement the freedesktop.org D-Bus spec; I'm working to fix this for 2.7.
