Upower.conf change didn’t work with Unity, but worked with Gnome-shell and Budgie.
I changed the current value in percentage-low in (org.gnome.settings-daemon.plugins.power) from 10 to 18, but have to wait until next battery drop.
In percentage-critical, the values is 3, what does that mean?
(What a mess Gnome is doing, really? Don’t they know that people use laptops, even in offices, not desktops these days? Committing suicide, most probably.) I put that in brackets, for it is just ranting.
In Openbox, I am using xfce4-power-manager and I don’t have any problems with locking on closed lid or notifications of low battery and changing the critical battery level. Do you think, can we just drop gnome power manager and use xfce4 one instead in Unity?
