[NAS4Free] Resume from S3 without video card

Hello,

I have installed NAS4Free on an old computer to use it for sharing files between the computers in my home network. Of course I don't want to waste too much energy so I use a script, that suspends the PC to S3, when it isn't used for a while, and I wake it up again by Wake-On-Lan. Up to this point everything works fine. Now I decided to remove the video card, because it only wastes energy and I don't need it for using the PC as NAS. Without video card also everything works fine, like if the video card wasn't removed :e (I configured the BIOS to ignore errors like missing video card). There's only one problem: when I suspend the PC to S3 and wake it up again, something doesn't work correctly, because I can't reach the NAS4Free-WebGUI nor connect via SSH (the only way to shut it down is to do a hard reset by pressing the corresponding button on the PC-case). Does anyone have an idea why the system doesn't resume from S3 properly without video card?
 
Re: Resume from S3 without video card

Hello,

You need to read the manual for the motherboard and check whether it has the capability for headless mode. First try switching off in the BIOS all messages (to show messages it needs video and keyboard). If your motherboard has an integrated video card, you can use it. Read http://en.wikipedia.org/wiki/Headless_system.
 
Re: Resume from S3 without video card

Hello,

I couldn't find any information about headless mode for my mainboard. But like I've already said, I set the option "Halt On" to "No Errors", so the boot process continues although there is no video card. As I said before, normal booting from switched-off-state (I think it's S5) and shutdown/rebooting works well, only if I want to resume from S3 ("Standby") there's obviously a problem (there are also no entries in system.log for the time waking up from S3). But as far as I know the BIOS isn't involved in the resume process from S3, because when I wake it up with video card and a monitor connected, in a fraction of a second the NAS4Free console menu appears, in contrast to normal booting, when it lasts about a minute and I also can see the BIOS screen or enter it. Another example is, that I had set a system password in BIOS on another PC and I only had to enter it when rebooting or resuming from S4, but not when resuming from S3. So my assumption is, that there is a problem in the resume process of FreeBSD, but I don't have much knowledge about Unix/Linux/FreeBSD and have no idea where to search for the error.

Sadly my motherboard doesn't have an onboard video card :( As the last choice, I would buy a really cheap video card as a "dummy" that doesn't waste much energy, but my preferred solution is, to get FreeBSD resuming from S3 without video card.

Maybe someone has an idea where to search for errors? :)
