But I thought there was a way to turn the backlight off > from the terminal? I think the problem is that the vga in FreeBSD does not support DPMS. This is problem on a lot of laptops, including my IBM T30. jhb posted a patch to acpi_video to support DPMS and started working a general vga support, but I don't think he's aver finished it and I am still using his patch. You can find it in the archives. Look for 'acpi_video_dpms.c'. It's been a LONG time, but it still works. I may have made some minor adjustments over the months that will be required to make the patch install, but it's still working for me with -current. If you have too much trouble getting it to apply, I can send you a copy of the patch I am currently running. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
