I have found some more strange things. If I switch to a regular terminal window (Ctrl-Alt-F2) and press the power button it does a regular shutdown, but if either at the login screen or logged into gnome it seems to cause a suspend shutdown that doesn't work. I have found a half-way solution? From this message. ================================================== Unfortunately the files under /usr/share/polkit-1 will be overwritten by next upower package update. A correct solution is to create a new config file under /etc/polkit-1/localauthority. /etc/polkit-1/localauthority/50-local.d/50-disable-suspend.pkla [Disable Suspend] Identity=unix-user:* Action=org.freedesktop.upower.hibernate;org.freedesktop.upower .suspend ResultAny=no ResultInactive=no ResultActive=no ================================================== It doesn't fix the problem completely, but it makes the power button do nothing, and removes suspend options? So now clicking on the icon in the upper right give shutdown and restart only? The power button does still work from a terminal screen. Not a perfect solution, but better than what it is now doing. > > -- > ====================================================================== > = Send your questions to ``ASK ZIPPY'', Box 40474, San Francisco, CA > 94140, USA > ====================================================================== > = Aaron Konstam telephone: (210) 656-0355 e-mail: > akonstam@xxxxxxxxxxxxx > > -- > users mailing list > users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have > a question?
