Comment 6 for bug 884686

I think I've found the source of the problem.

Since I'm a kubuntu user, I didn't notice the new ubuntu uses lightdm as the default display manager in place of the old gdm.
The upstart service of samsung-tools is started only when the display manager is already running, but it only checks for gdm and kdm.

I've added support for lightdm as well, so the bug should be fixed now.
Please test the new samsung-tools (2.0~ppa1~loms~oneiric~test7) available on my testing repository and let me know if it's working:
