I generally like the idea, but my concern is with my experience having run thermald out of the box (both upstream as well as the Federa packaged version). On my commodity HP Spectre laptop, when thermald is running, it causes four kidle-inject process to totally soak spare CPU. And now I'm not able to play even a single youtube video, and any appreciable effort in Firefox also causes these processes to tamp down, making everything super sluggish and basically terrible. I reported this experience a year ago not knowing at the time it was thermald that was causing this behavior. It took me a while to make the connection. https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/BK2DVB4PA37FMB2DTMUI4YBM7YDGSJTK/ That definitely cannot happen by default for anyone. It's so non-obvious what's causing it, and such a bad experience, that I'm not willing to foist it on a single person. I'd sooner foist it on hundreds, at least the screaming will be loud enough everyone will figure out what's going on. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
