After booting into the ubuntu login screen and clicking on my user name and entering the password, I get a dialog stating that gnome-power-manager is still running. The dialog presents 2 buttons, 1 to Cancel and other to Logout Anyway.

This issue happens about 50% of the time and I don't remember doing anything related to power management recently. Also, even if I don't choose any option in the dialog it goes away after about 30s.

This is happening on a desktop machine as well as a laptop. On the laptop I have configured power management for myself (not for gdm) whereas in desktop I have not configured power management for any user.

This is only an annoyance but still I would like to fix it, especially on my desktop where I am interested in getting it auto-login ASAP into my userid.

Any ideas why this could be happenning?
