I can confirm this behavior when booted using BIOS mode. VT works fine after KMS is loaded using EFI mode. I can confirm this with nvidia-modeset, and radeomkms as well. All work fine when using EFI. I think this may be related to: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210647 |
Created attachment 168187 [details] dmesg Hardware 2012 Macbook Air (Sandybridge) Brightness is set to 0 when loading i915kms from console with kldload. Blindly (or via ssh) typing intel_backlight 80 restores brightness. Setting hw.acpi.video.lcd0.fullpower = some value in loader.conf does not help.
