Sorry for posting on such an old thread, but every time I google FreeBSD and suspend/resume I wind up here, so I will assume that others do as well. That being said, fire up
vim,
ee,
emacs, whatever else you may use and edit
/etc/sysctl.conf as follows:
Code:
hw.acpi.lid_switch_state=s3
hw.acpi.reset_video=1
Save and close. The next part is completely optional, but while video should now be working on resume, most likely the mouse will not be. Restarting the mouse daemon will bring it back, but for a more seamless solution open
/boot/device.hints in your favorite editor (I chose to do this with an editor rather than echo so I could keep it with the other hints for psm), and insert:
Code:
hint.psm.0.flags="0x2000"
Save the file. You will get a warning about saving a Read Only File, and as such, the standard disclaimer "DO THIS AT YOUR OWN RISK" applies. Now reboot the machine, close the lid, and wait for the machine to suspend, once it does, open the lid, and hopefully you should be in business. A side note that might help: I tested this on a Toshiba Satellite C665D with an ATI M880G chipset, and an ATI HD4250 video card, version of FreeBSD is 9.0 RELEASE with a generic kernel. I have seen indicators that this solution will work with NVIDIA, as well as ThinkPads and several other platforms.

I think that it has less to do with the FreeBSD devels, and more to do with the fact that the BIOS manufacturers don't implement the ACPI standard to the letter, and seem to think that the world at large only uses various versions of Microsoft products. As such they only test their implementations of ACPI under those products, and the rest of the computing community gets left out.
I hope that this solution can save someone else a few hours, a lot of reboots, and a headache to get this working.
