Nothing surprising here. Few systems have S1. > hw.acpi.power_button_state: S5 > hw.acpi.lid_switch_state: S1 > hw.acpi.standby_state: S1 > hw.acpi.reset_video: 1 > hw.acpi.disable_on_poweroff: 1 I should make these default to min(hw.acpi.supported_sleep_state) instead of just S1. But no problems here either. You can try setting hw.acpi.reset_video=0 to see if it helps your screen resume. Check out the ACPI section from the FreeBSD handbook. Some people put a lot of effort into documenting things and it seems that no one has read it. -Nate
