Description of problem:
When I lock the screen power saving mode kicks in. Five seconds later power saving mode exits (but the screen is still displaying a black color).
This would not matter except the power draw difference is huge:
55 watts when in use, and 20 watts when in power saving mode.
I'd like to use power saving mode if possible.
F29 latest updates. DP cable. Intel 630.
Might have got the wrong component, sorry about that.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Lock the screen
2. Watch watt meter drop from 55 watts to 20 watts
3. Wait 5 seconds
4. See backlight come back on again
5. Watch watt meter jump back to 55 watts
Does not stay in power saving mode
Stays in power saving mode
This command does not keep the display in power saving mode for 60 seconds:
busctl --user set-property org.gnome.Mutter.DisplayConfig /org/gnome/Mutter/DisplayConfig org.gnome.Mutter.DisplayConfig PowerSaveMode i 1; sleep 60; busctl --user set-property org.gnome.Mutter.DisplayConfig /org/gnome/Mutter/DisplayConfig org.gnome.Mutter.DisplayConfig PowerSaveMode i 0
