Sony Vaio PCG-C1VRX/K Picturebook, Suspend to Ram works, but has a strange effect on the idle display

Quoted 11 lines · Benedek Frank

Now, I can suspend and resume with the script I wrote for it, but even while suspended, the screen wont turn 100% off. If I tilt in in a way, about 160degree angle, I can see some text on the screen. Of course I can barely see it, but I can for Christ`s sake, while it should be off. For an "untrained" eye it seems the screen is black of course, but I got suspicious after a few days of being able to suspend, as the laptop wasnt 100% quiet. The screen is making a little, very very little scratching noise, that I cannot really describe its more like an "electric" noise. Its bugging me, as it must be using some of my battery, while it should not be using anything other than what the RAM needs to not loose its stored memory.

If you don't have a PCI driver bound to your video device, the kernel will not actually power it down. This is probably a deficiency in the kernel, but still. On most machines the BIOS will power it down anyway, but this isn't always the case.

So it means there isnt a way I can make it work? How can I tell the BIOS to shut the screen? Do I need to enable that dusty APMD to do it for me?

And the screen is almos shut, so it is definetally dimmed to the extent where it cannot be seen, except with suspicious eyes. And when I resume, which is open the display and hit a key, I can see that the display turns off for a second, and then on again. And when I suspend without that boot time parameter, the screen is off when I do the suspend, just there is no way to wake it up again.

So my new question is, isnt there a tool, that wakes up
Video for a Ati Mobility P/M card? I also have a Dell 700m, with an Intel onboard card, that comes with the centrinos, and there is a tool, that need to be run upon awakening, and the video will post.

You need a driver that will power down the PCI device.

That boot parameter has nothing to do with suspend (the only code path it's involved with is run on resume), so I doubt that.

If the s3_bios option works, then vbetool will probably work as well.

We need some sort of solution for this. It would be easy enough to write a PCI driver that binds to any video device and puts it into D3 on suspend.
