My anecdotal evidence says most home users walk away from the computer and let the default power management settings do whatever they do, so they don't have to worry about rebuilding their workspace state every day. Even laziness is sufficient to explain that behavior - few GUI environments can shut down without getting the user involved in making decisions about unsaved changes, terminating stuck apps, etc. I realize the plural of 'anecdote' is not 'data', however, so it would be helpful to have some data. My netbook has low uptimes because it keeps getting hosed on resume from disk, not because I shut it down. As far as the right thing to do to 'save the earth', there are a bunch of variables. 'How much power does it take to keep DRAM fresh?' vs. 'How much power does it take to book an OS from power-hungry hard drives'. Some new RAM types in the work don't need DRAM refreshes. Engineer down the power cost 'till it's negligible. Linux could come up with some sort of COW-like scheme to start running out of suspend-to-disk space instead of restoring to RAM first (then you can suspend to flash, e.g.), etc. And none of that addresses the macroeconomic opportunity cost of final-solution energy research as a function of GDP as a function of productivity (but now I'm completely off-topic). -Bill -- Bill McGonigle, Owner Work: 603.448.4440 BFC Computing, LLC Home: 603.448.1668 http://www.bfccomputing.com/ Cell: 603.252.2606 Twitter, etc.: bill_mcgonigle Page: 603.442.1833 Email, IM, VOIP: bill@xxxxxxxxxxxxxxxx Blog: http://blog.bfccomputing.com/ VCard: http://bfccomputing.com/vcard/bill.vcf -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
