I have following modules compiled and loaded cat /etc/conf.d/modules modules="thunderbolt appledisplay facetimehd binfmt_misc" The thunderbolt display would turns on during boot before lightdm greeter (login screen) and sometimes keep working after I log on, but most of the times it turns off right before the greeter appears and becomes black. Sometimes log out and login repeatedly helps to activate the thunderbolt display. I can, however, always select and use the speakers on the thunderbolt display. xrandr output: Screen 0: minimum 320 x 200, current 2560 x 1440, maximum 16384 x 16
