I'm using Xubuntu 14.04 64 bit. I know that question been asked a billion times, but all of them consist of editing following file:
That file does not exist on my system. I tried
com.xubuntu.enable-hibernate.pkla but doesn't exist either,
locate command doesn't find it.
Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:
Change the value of "ResultActive=no" to "ResultActive=yes" in both, press ctrl+x to exit the file. It will ask to save the change or not. Press Y to save the change, if you're on Ubuntu restart your system.
Just tried this on Xubuntu 16.04, and Ubuntu 16.04. and it also works.
For Ubuntu 16.04 I had to reboot for it to work.
