However, it's not the worst case. The worst case is if someone has an external monitor connected which they're not actually using (it may be hidden or being used with some other input or just turned off). This does happen: https://bugzilla.redhat.com/show_bug.cgi?id=582525 that bug is already inconvenient for some people; if they have laptops with bad lid switches it'd be much more inconvenient. The only active display would be the external display they weren't actually using. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
