Hello!
I'm struggling to get a Vaio-laptop with NVidia graphics to work properly.
NVidia's own driver (from x11/nvidia-driver) does not "see" the laptop's own
built-in screen. Linux users have solved this problem:
http://code.google.com/p/vaio-f11-linux/wiki/NVIDIASetup
but that requires reading ACPI-data via the Linux' proc-filesystem:
/proc/acpi/video/NGFX/LCD/EDID
FreeBSD's /proc does not have the acpi subdirectory, and neither does our
/compat/linux/proc
I'm sure, acpidump can extract the needed info, but I don't know, how :-(
I put the disassembled dump (acpidump -dt) of this laptop to:
http://aldan.algebra.com/~mi/VPCF11M1E.acpidump.bz2
Is the necessary information (128 raw bytes or so) in there?
Could somebody give an idea? Thanks!
-mi
P.S. The laptop runs 8.1-prerelease/i386
