A quick calculation showed me that,
assuming there are 10 million Fedora computers in the world, running 7/24,
saving 2W per computers saves about 1 relatively large size tree (40
tons) every 2.3 days.
Just for the record.
Considering:
- the 2W savings is only on a patched radeon driver, AIUI
(although it could theoretically be ported to other drivers
such as nouveau (not intel), given enough specs)
- the savings is only if the screen is otherwise not updating
- if the screen stays this way for more than a couple of minutes,
the screensaver will kick in
this estimate is many orders of magnitude too high.
That being said, just flip the default already.
