We would not pre-empt upstream defaults for this sort of thing. Apart from anything else, the Fedora X maintainers are heavily plugged into upstream, so if our X folks thought it made sense to enable the PM code by default, they'd already have changed that upstream. I don't follow this closely, but from what I know, the PM code is still fairly new and is not considered reliable enough to enable by default yet. The safest setting is still to run the fans in airplane mode - it may be noisy, but at least we're pretty sure we're not cooking your GPU. :) -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
