Hello, on my Laptops xfce4-power-manager is adjusted to go into suspend mode after 15 minutes of inactivity (in battery mode as well as in power-supply mode). This does not work at all "in battery mode" which means noting happens and the machine is still running while everything works properly in power-supply mode. I checked dmesg --> noting related found. Additionally I tested also the suspend due to a low battery status (naturally in battery mode) and this works either. The suspend functions work also properly if triggered through the xfce-logout-button. For testing purposes I activated suspend by closing the lid (also a feature of the power-manager). To my surprise this works also like a charm (in both, battery and power-supply mode). To sum up: Only the suspend due to inactivity in "battery mode" is broken. Best regards Gerold
And the reason I have just found is that a line is missing from the xfce4-power-manager configuration xml file. It needs: inactivity-sleep-mode-on-battery integer 1 I set this parameter by using the 'Settings Editor' and adding the new action to the list under xfc4-power-manager. This causes the change to be made in config/xfce4/xfconf/xfce-perchannel-xml/xfce4-power-manager.xml Value 1 is for 'Suspend' (deduced from the value for other actions in the same file). I am using a completely clean xubuntu 16.04 installation, on a 64 bit Samsung Laptop. Like you, suspend also works for me for closing the lid and so on, just not for inactivity, claiming: "GDBus.Error:org.freedesktop.login1:SleepVerbNotSupported" I spent a heck a lot of time searching for a solution in amongst the maze of stuff there is about power saving (mostly about hibernation). I had to keep reminding myself that the 'Suspend' action on the settings GUI didn't seem to be reflected in the xml configuration file.
I found another missing element on my xubuntu 16.04 system. It needed critical-power-level, as an integer. Without this the critical power action did not seem to be enacted. Does this need reporting against xubuntu, or will reporting here be enough? There may be other settings missing that I've not yet encountered. When changing the values using the normal configuration GUI, the values seem to be saved, but I know not where. They don't seem to take effect. My latest file (edited using the settings editor rather than directly) is: <?xml version="1.0" encoding="UTF-8"?> <channel name="xfce4-power-manager" version="1.0"> <property name="xfce4-power-manager" type="empty"> <property name="power-button-action" type="empty"/> <property name="lock-screen-suspend-hibernate" type="bool" value="false"/> <property name="logind-handle-lid-switch" type="bool" value="false"/> <property name="blank-on-ac" type="empty"/> <property name="blank-on-battery" type="int" value="10"/> <property name="dpms-enabled" type="empty"/> <property name="dpms-on-ac-sleep" type="empty"/> <property name="dpms-on-ac-off" type="empty"/> <property name="dpms-on-battery-sleep" type="uint" value="15"/> <property name="dpms-on-battery-off" type="uint" value="20"/> <property name="brightness-switch-restore-on-exit" type="int" value="1"/> <property name="brightness-switch" type="int" value="0"/> <property name="lid-action-on-battery" type="uint" value="1"/> <property name="lid-action-on-ac" type="uint" value="0"/> <property name="inactivity-on-battery" type="uint" value="29"/> <property name="critical-power-action" type="uint" value="3"/> <property name="sleep-button-action" type="uint" value="1"/> <property name="brightness-on-battery" type="uint" value="60"/> <property name="hibernate-button-action" type="uint" value="0"/> <property name="show-tray-icon" type="int" value="0"/> <property name="inactivity-sleep-mode-on-battery" type="int" value="1"/> <property name="critical-power-level" type="uint" value="10"/> </property> </channel>
I found another missing element in the xml file. 'critical-power-level' needs to be added, on my xubuntu 16.04 system at least,otherwise the action does not take place at the right time (if at all). If I changed the value on the configuration GUI it was saved, but I don't know where, and it didn't take effect. By adding this element the action now takes place at the specified time. Does this need to be reported to xubuntu as well (or instead)? My file is now as below (edited using the Settings Editor, not directly). Is anything else missing? <?xml version="1.0" encoding="UTF-8"?> <channel name="xfce4-power-manager" version="1.0"> <property name="xfce4-power-manager" type="empty"> <property name="power-button-action" type="empty"/> <property name="lock-screen-suspend-hibernate" type="bool" value="false"/> <property name="logind-handle-lid-switch" type="bool" value="false"/> <property name="blank-on-ac" type="empty"/> <property name="blank-on-battery" type="int" value="10"/> <property name="dpms-enabled" type="empty"/> <property name="dpms-on-ac-sleep" type="empty"/> <property name="dpms-on-ac-off" type="empty"/> <property name="dpms-on-battery-sleep" type="uint" value="15"/> <property name="dpms-on-battery-off" type="uint" value="20"/> <property name="brightness-switch-restore-on-exit" type="int" value="1"/> <property name="brightness-switch" type="int" value="0"/> <property name="lid-action-on-battery" type="uint" value="1"/> <property name="lid-action-on-ac" type="uint" value="0"/> <property name="inactivity-on-battery" type="uint" value="29"/> <property name="critical-power-action" type="uint" value="3"/> <property name="sleep-button-action" type="uint" value="1"/> <property name="brightness-on-battery" type="uint" value="60"/> <property name="hibernate-button-action" type="uint" value="0"/> <property name="show-tray-icon" type="int" value="0"/> <property name="inactivity-sleep-mode-on-battery" type="int" value="1"/> <property name="critical-power-level" type="uint" value="10"/> </property> </channel>
Sorry, I added the same issue twice. The first disappeared and then came back.
Still the same in 1.6.0
I have xfce added to my ubuntu 16.04.1 install. It reports as v 1.4.4 I noticed via the settings editor, the critical battery level was missing from the XML file, and the GUI showed the default 10%. As soon as I used the GUI to modify the value to 9%, the setting was created in the XML file. I did have the battery suspend settings in the XML file already. If they were missing, I guess that they were added by my previous edits to those settings.
