My system won't wake up (or at least the DVI video won't)

[gtd885a]

I've been having a problem for quite a while where I can't get the video on my system to wake up if Sage has been asleep for a while and my TV was off/on another input. The ONLY way I can get the video back is to hit the sleep button on my keyboard twice (put it to sleep and wake it up), which is annoying for a number of reasons First it means I have to get my keyboard out, which I don't want to do. Secondly, I've noticed that after I have to do this, my channel changing (over firewire) never works quite as well.

I originally thought this was an issue with my motherboard, but after replacing the board (with a totally different chipset, btw), I still have the same problem. I realize this is probably not SageTV's fault, but it is only happening on the box that I am running Sage on and I was hoping someone could help me get past this annoying problem.

A little more about the problem: I have noticed that sometimes, I can actually hear the audio even when the video won't "wake up", so it seems that the box is not really asleep. It's almost as if the video card turns off the output, or the TV just doesn't recognize that there should be input. So, I was thinking this could be a video card issue or possibly an issue with my TV.

Here is my setup (remember, I had a deffierent motherboard before and had the same problems). I have an ATI Radeon 9800 (running as Pro), AMD 64 3400 (754), Soltek SL-K8TPro board, 1x36GB WD SATA Raptor, 1x200GB Seagate SATA, 2x512MB pc3200 Kingston. I'm using firewire to capture from Motorola 6200 and change channels. I have an IR receiver on serial port and am running IRAssistand and winLIRC. Not sure if it matters, but I'm running the last beta version of Sage and nVidia purevideo. I have tried all combinations of sleep settings in Sage and windows.

Oh, yeah, my TV is Samsung HLP5063w, and I'm connected via DVI out of the Radeon.

Any advice is greatly appreciated. Thanks in advance.

Update:

I just turned on the system, and like usual I couldn't get the video to show up. This time (as happens sometimes), I could hear the audio. So, just for the heck of it, I unplugged the DVI connection from the graphics card and plugged it back in, and the video was there!!! So, does this mean that the TV is just not picking up the signal for some reason? I google a bit and couldn't find anything. Or could it be a graphics card issue? I guess I could try my geforce 6600 gt from my main system and see if it still happens.

Any suggestions/ideas?

Ever since I've installed 3.0.14 (and now 4.0), I've had this recurring problem with SageTV. If I leave SageTV up in full screen mode, shut off my TV, wake up the next morning and turn on my TV, I get "No signal" from the DVI input. Moving the mouse around or hitting any keys has no effect. Nothing I can do wakes it up. Other notes:

1) I have Windows' screen saver disabled
2) I have power management disabled completely
3) If I have SageTV in either windowed or full screen mode, this happens. If SageTV is not running, the TV powers up normally and I get a picture, so it's definitely SageTV related
4) No amount of adjusting the screen saver time in SageTV has any effect
5) DX9 Overlay mode is disabled, because it kicks on the fan on my video card if I enable it

It's connected from an ATI Radeon X800 via DVI directly to the TV. Any thoughts on why this could be happening?

What ATI driver are you running? I had this exact problem with Cat 5.8 or 5.9 (Can't remember which one) but not with previous versions or 5.10 which I'm running now.

I have this problem as well sometimes with an ATI grphics card. I found that if i toggle the fulle screen mode or hit the windows key the screen comes back. Will try the latest drivers when i get a chance and see if this helps.

Its the ATI catalyst drivers--its a known problem with DVI outs and no fixes have been found yet. Unlike Sleonard, I have this problem with the cat 5.10 too. Might want to try downgrading your driver versions and see if that clears it up.

Yeah, I switched the card with the GeForce 6600 GT in my main system and it hasn't done it since. Don't really like giving up my video card, but at least I know what it is now (lol, after buying a new motherboard - I really did search but didn't find anything - don't know that I ever put together the DVI/ATI/Catalyst thing).

Ever since I switched video cards I have experienced quite a bit of video flaky-ness and much higher CPU usage (80-100%, where it was in the 20% ballpark before). I may need to reload the system again if I'm going to keep this card where it is.

Edit: Oh, yeah, thanks for the replies! If anyone finds anything that works for them, please let us know!

I have the blanking problem as well even with the latest 5.11 Cats.

Here is what I did... I used studio to bind a Command Line Program to
Custom1 that changes the resolution to 1080i and then back to 720p and that wakes up the DVI interface. It was my first shot at Studio, and I was quite proud of it. It was rather annoying, but this work around lets me use DVI finally. If you were not aware of it... the component output on the Radeons don't black out like the DVI does!

I take that back. I didn't experience the problem after upgrading to 5.10 until a few days ago when it reappeared. I think I'll be going back to 5.7 or 5.8.

FYI Cat 5.6 are the only drivers so far that will wake the DVI properly for me. There is actually another thread started on this http://forums.freytechnologies.com/f...ad.php?t=13983
