You're missing the nuance of the debate. What I mean by 'problem case' is that, according to mjg59, lid sensors don't always actually work correctly; there are many documented cases of systems whose lid switches report incorrect state, especially at boot. So we can't just say 'always enable the external monitor and disable the internal monitor if the lid switch says 'closed' and there's an external monitor connected', because the lid switch might be lying. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
