S3 Problems .....

[thepieman]

Hi,

Sorry for the long post but i've tried a lot to get this working but still no luck

I've recently started using gbpvr as the front end to my htpc. I'm happy to say 99% of it works flawlessly

However i decided to try and set it up so that it would go into a suspended mode evey 30 minutes (S3). This nearly worked

Basically what happens is that I can put the system into S3 ok (fans off etc) but when gbpvr wakes the system to record a program the screen output is blank (i'm using the tv out of gfx card). It is initializing the card as i can see the effect on the tv (goes from black to a very dark gray). Whats more it records the program fine !!! It's just that i cant see what it's going. Whats stranger is that if i move the mouse or press a key on the keyboard the display turns on , problem is that under normal conditions it doesnt have a keyboard or mouse attached. Although moving around with the remote control wont bring it back but the movement is registered as i can see that i have navigated menus when i get it back with the mouse.

Another thing is that if i suspend the pc then use the remote or the case button to bring it out of suspension everything works fine , it only seems to blank the screen when gbpvr does it.... weird ....

The only thing i can think of that might be causing this is the way it is brough out of S3 by gbpvr. Since the case button and the remote work fine (pressing the power button on the remote is physically the same as the button as it's wired throught the IR sensor pcb). I also edited the registry to allow waking with the keyboard and mouse to see if that fixed it ... it didnt , but it did resume properly ith the mouse and keyboard.

In a desperate attempt i even wrote a script to change to resoultion to 640x480 and back to 720x576 hopeing that might make the screen reappear ... it didnt

I also updated the drivers for the gfx card 77.72 -> 81.92 ... had no effect

Oh and i also notice that if i try to use VNC to veiw the screen when it's blank it does connect but i dont get any screen only a title bar ... it's as if the screen res was set to 0x0


Heres my setup in more detail , anyone got any ideas or maybe had a similar problem ???


Thanks
Simon

Im pretty sure i read somewhere else that this is normal behavior.

My system does it too.

The thread that i read was that, if the PC is powered on by something other than a user, its assumed a user isnt sat at the screen waiting for it to power on, so the screen output is not switched on. When the resume is user-initiated, then obviously theres someone sat there, and so the screen output is switched on.

Thats the logic it was designed to follow, so when you do something to trigger it, the menu will appear, but when its a GBPVR scheduled recording, it wont...

Not sure about your quote about VNC though. Ive only just started using it, maybe theres a setting that will make it work regardless of what your monitor/TV output is.

ahhhhhhh .... well thats saved my days of head scratching

I'm still wondering why commands from my remote wont reactivate the screen though since they are being registed and i can control gb-pvr "blind". Maybe it's because the movement is software driven (through imon control software) and not a real keyboard/mouse , who knows it's a mystery :p

Thanks for the help though
