Disable lock screen dimming in 16.04

Solution 1:

Ubuntu 16.04

I have also been trying to figure out how to stop the lock screen from dimming. I can not seem to find anything associated with the screen dimming when going to the lock screen that I can edit/tweak.

I tried all the usual suggestions of

gsettings set org.gnome.desktop.screensaver idle-activation-enabled false

gsettings set org.gnome.desktop.session idle-delay 0

gsettings set org.gnome.settings-daemon.plugins.power idle-dim false

but none of them worked.

**** WORKAROUND ****

However invoking an activity once the dimming starts seems to then follow what ever settings you have enabled in the system settings > Brightness & Lock > settings.

The way you can stop it is by locking the screen then typing a few random characters into the password prompt. It will now no longer dim.

It's not a perfect solution by a long shot as the user has to invoke the lock screen manually to get it to work but it may help.
