[Lev Serebryakov]

Hello, Freebsd-x11.

  I'm using 10-STABLE on old Laptop (Sony Vaio) with Intel adapter (it has
 switch Intel/nVidia and I use Intel one), and with "old" Xorg xfce4
 brighness plugin could control brightness if acpi_video.ko is loaded.

  I've tried NEW_XORG, it mostly works, but all hw.acpi.video disappears and
 I could not find any way to control backlight brightness :( xfce4
 brightness plugin shows "No device found" too.

  Is it known problem? Is here any way to control brightness in such case?
