Hi,
2. I've read bad reviews about webcam having poor quality on
GNU/Linux, so I would assume it will be the same on FreeBSD with
webcamd and not worth the $30? (which also frees up space for
3x3 antenna)
Yep, the webcam works with webcamd but the quality is not great...
4. How far is the AMD64 kernel suspend/resume? What do you mean by
video doesn't resume?
I run 10-CURRENT :
FreeBSD laptop.martymac.org 10.0-CURRENT FreeBSD 10.0-CURRENT #12
r231062M: Mon Feb 6 10:29:35 CET 2012
marty...@laptop.martymac.org:/usr/obj/files/Src/sys/GENERIC amd64
with all.13.1 patch (no more available) from :
http://people.freebsd.org/~kib/drm/
3D acceleration works well, as well as suspend/resume when Xorg
has been
started (black screen if on console).
Best regards,

This is great news!
I just finished some other stuff, so hopefully I can take a renewed
look at
brightness and the fan issue.
Thanks for woking on this, Matt. I, for one, would be happy to have
the volume and de-lighted to have brightness working on my T520!
(Sorry or the weak pun.)
So far it looks like acpi_video attaches, but the lcd0 device is not
active.
More interestingly, if you press brightness shortcuts, acpi_video can
see the brightness value change while screen does not actually change.
My conclusion based on bullshit and poking around in the acpidump, is
that possibly either:
1) We need to call some ACPI handle to put ACPI in charge of
brightness (google acpi brightness trapdoor)
2) acpi_video is attaching to the nvidia optimus hooks (yes, they're
there, I know we don't have that option) and is missing the IGD video
(VIGD/PEG etc)
3) Something else is wrong with either acpi, acpi_video, or bios that
is preventing ACPI from working?
I am going to take more of a look tonight.
I think I can just hack in some ACPI calls straight to the ec if that
will work, which might also include the correct ones to resume the
display without KMS?
Calling some _ON function or something perhaps
Thanks!
Matt
I have brightness control through raw acpi..."\_BCL" and friends seem
to do nothing.
Most of the video methods differentiate between \VIGD (which seems to
be a check for integrated graphics vs optimus, but that's still a guess)
If \VIGD is true, brightness commands are sent to the EC, where they
don't seem to do much yet. This is probably where we could enable
something via EC/ibm-acpi?
If \VIGD is false, brightness commands are handled in ACPI, although
coarsely, via \VBRC.
\VBRC seems to allow control over the backlight, at least, so those of
you with sore eyes or the 3-cell battery may have some success using
the acpi_call port (Danger!)
kldload acpi_call
acpi_call -p '\VBRC' -i n (where n is 0-10)
Still hacking :)!
Matt
Can anyone verify that suspend/resume is now broken on x220 with latest
HEAD and the KMS patches?
Suspend bounce causes crash, resume beep makes modem sound and hangs,
logs indicate only suspend.
hw.pci.do_power_resume=0 causes no change.
The acpi_call hack works on console as well, so at least we have some
ability to control brightness for now.
The next step is going to be figuring out why EC does nothing, or it
would work out of the box I think.
If that's a dead end, we can patch acpi_ibm to use \VBRC maybe.
Also, once xorg & xfce load, my power usage goes from 9W tuned to
24W...I'm sure that's because patch is still in development.
