Running a clean install of ubuntustudio 14.04 the suspend and resume works when using the power button or selecting it from the user menu but is not available in the xfce4-power-manager-settings. Only "Lock Screen" or "Nothing" is available for lid close action.
http://docs.xfce.org/xfce/xfce4-power-manager/faq
Suggests that it is likely permissions issue since suspend/resume clearly works.
My single user on a single user system has the following group memberships: username adm cdrom sudo audio dip plugdev lpadmin sambashare
Any suggestions? I'd rather not fry my new hdd because I forgot to suspend and just close the lid.
Updates:
- Changing "/etc/systemd/logind.conf" settings have no effect.
- This appears to be a bug in upower https://bugzilla.redhat.com/show_bug.cgi?id=1005234
- I've confirmed this is not an issue with my hardware on the standard ubuntu desktop (using a live drive)
- I've confirmed this is not an issue with xubuntu!?! (I had to enable suspend in the xfce4-power-manager-settings but it was an option)
- Changing kernel to linux-general has no affect.
- xfce4-power-manager –dump & sudo xfce4-power-mangager –dump

Install
pm-utils
Reboot
Reference: [Solved] Issues with xfce4-power-manager-1.2.0
Discussion resume that:
upower
is relying onpm-utils
to check for suspend/hibernate capability.The broken link in the reference page should point to related bug report: Debian bug#639754 [upower] upower doesn't verify correctly the "suspend" and "hibernate" capabilities correctly
Not sure about this as
upower
package hasDepends: pm-utils | systemd | systemd-services
. I thought they should be alternatives. So may be there is other solution usingsystemd-services
which is installed by default.
