My previous experiences with using transparency (on Windows) have indicated it causes serious battery drain. I'm loving Hera, but the battery usage is very poor and I'm wondering if it has to do (at least partially) with transparency. I have used "tlp" but no noticeable improvement.
I found the page on turning off transparency on Loki and Freya but it didn't work for me. I also tried "System Settings >> Desktop >> Appearance" to switch "Panel translucency" to both settings but no luck. Every time I open a new Terminal it is transparent. Only when I lock it to one side of the screen does it lose transparency.
So how do I turn off ALL transparency on Hera?
UPDATE: The answer helped me turn off transparency on Terminals but that did NOT lead to any noticeable improvement in battery usage.
