Fn). The system isn't stuck and could be properly rebooted by pressing the power button (most likely through SSH too). Before login into DE display managers like sddm and lightdm work properly even when DisplayPort 1.2 is enabled. Hardware in my case: the i7-4790 CPU with integrated graphics that is the o= nly graphic card; Dell U2414H monitor. Windows 10 Pro works properly on this hardware and with that monitor connec= ted through mini displayport with and without the DisplayPort 1.2 mode is enabl= ed in the monitor itself. System: FreeBSD 14.1-BETA2 x86_64. The drm-kmod drivers set from ports is installed and i915kms added into the kld_list in /etc/rc.conf For more information read my emails in the freebsd-stable mailing list: https://lists.freebsd.org/archives/freebsd-stable/2024-May/002132.html
