But > it'd be nicer if I can just directly expose the culprit(s). I've been seeing the same, so I just did some testing. It appears to be taking around 45-50s from luks password to GDM. I timed it with a stopwatch (and non-graphical boot) and I see that it takes about 20s to get to the point where it starts GDM, then the screen blanks for about 25s before GDM comes up. I tried using an F34 kernel to see if that would help: same result. I tried booting with permissive=1 on the kernel commandline... 22s boot, only about 1s from GDM start to graphical login. So it appears to be an SELinux issue. I suspect but cannot prove that it's related to a number of AVCs related to DBUS that I see in selinux-troubleshooter. _______________________________________________ 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 Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
