I have the same issue here on a Dell D610 laptop, running edgy, upgraded from a dapper installation yesterday.
It looks like suspend and hibernate works fine from gdm, but i'ts not possible to got to suspend/hibernate mode from gnome-power-manager, or from the logout dialog. Selecting suspend/hibernate just makes lock screen appear, without even an info baloon explaining it failed. It seems to be a user right issue, but as tz said, I was not able to find a way to solve that. -- Wont suspend (or hibernate), won't say why, and is annoying. https://launchpad.net/bugs/50785 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
