I am using FC5 and suspend2 kernel 2.6.16-1.2080_2.rhfc5.cubbi_suspend2 on a desktop. Hibernate to disk and resume are working fine and GPM set to hibernate if inactive. The Hibernate on no activity works fine if there is a user logged in. BUT if nobody logged in, it just sits for hours and does not hibernate.

I have set the gconf key /apps/gnome-power-manager/ac_sleep_computer to value 60 as a mandatory setting using gconf-editor.

Any ideas what could be stopping this when no users logged in, or logfiles etc. I should look at? /var/log/messages and /var/log/hibernate.log don't give anything.

Thanks
