Nice!
I totally borked my 13.04 desktops (linux 3.6.6 & 3.7-rc4 -- Unity & GS), this morning, by installing "caffeine-indicator" in Raring. I even killed LightDM. LoL!
Thank heavens for "ppa-purge"!
I'll see if I can break it again with 3.7.0-0...
EDIT
Works on my LegacyStein machine.
Code:
vindsl@Zuul:~$ uname -sr
Linux 3.7.0-0-generic
Er... we're not supposed to be using 'raring-proposed' or are we?!?!?
