suspend2ram/ hibernation on hp pavilion dv7

[kuba_g]

Hi!

Couple of days ago I've installed FreeBSD 8. I have already solved most of my problems (wifi, graphics , sound etc) but I have no idea how to solve a problem with suspend :/

After:

acpiconf -s 3

system is suspending to ram, but when it returns everything works fine expect laptop monitor- screen goes black.

I had the same problem on linux. I solved it by changing 'nv' driver to 'nvidia' in Xorg config. In FreeBSD I am also using 'nvidia' driver but it isn't helping at all.

Any suggestions ??

Notebook:
HP Pavilion dv7 1299ew
Freebsd 8 amd64

Have you read the Nvidia's driver documentation to check whether it say something about suspend support?
Anyways, suspend/resume on FreeBSD is still nothing to brag about ..
I solved my screen issues (i915 driver) but the bge(4) is a no go at all ..

Known Notebook Issues

There are a few known issues associated with notebooks:

* Display change hotkey switching is not available on all notebooks. In some cases, the ACPI infrastructure is not fully supported by the NVIDIA FreeBSD Driver. Work is ongoing to increase the robustness of NVIDIA's support in this area. Toshiba and Lenovo notebooks are known to be problematic.

* ACPI Display change hotkey switching is not supported by X.Org X servers earlier than 1.2.0; see EnableACPIHotkeys in Appendix B, X Config Options for details.

* In many cases, suspending and/or resuming will fail. As mentioned above, this functionality is very system-specific. There are still many cases that are problematic. Here are some tips that may help:

o In some cases, hibernation can have bad interactions with the PCI Express bus clocks, which can lead to system hangs when entering hibernation. This issue is still being investigated, but a known workaround is to leave an OpenGL application running when hibernating.

* On some notebooks, PowerMizer is not enabled by default. This issue is being investigated, and there is no known workaround.

* ACPI is not currently supported on FreeBSD As a result, ACPI hotkey events are not supported.

* The video overlay only works on the first display device on which you started X. For example, if you start X on the internal LCD, run a video application that uses the video overlay (uses the "Video Overlay" adapter advertised through the XV extension), and then hotkey switch to add a second display device, the video will not appear on the second display device. To work around this, you can either configure the video application to use the "Video Blitter" adapter advertised through the XV extension (this is always available), or hotkey switch to the display device on which you want to use the video overlay *before* starting X.
