No ideas? That's a really annoying issue. Contacted AMD Support (German; don't know if this is "good/real" support): Install latest drivers and updates o0
Well, I get this error everytime I install the latest catalyst drivers so that's not really helpful at all...
Today I replaced my X850 XT by an old Radeon 9600SE from Sapphire. After I installed the Catalyst Legacy 10.2 driver I tested again by turning off my display: argh!!! It happens again! So I think it is really driver related and no hardware issue - or there's a bug in hw design since a few generations o0
I have found some effective information here.
Thanks fo sharing.

Okay, I'm really pissed off now...
So far, that's what I know:
- Linux (oss driver): works
- Windows (no driver): works
- Windows (Omega driver): works
- Windows (Legacy Catalyst 8.1 - 10.2; yes, I've tested them all): fail!
- Using a Radeon 9600SE: behaves exactly the same!
- Using a Geforce 4 Ti 4200: No issues in every possible configuration!
Because I have no erros in a lot of cases I suspect the official driver and not a hardware issue. I would use the Omega drivers but then I have display errors in some applications (they are based on an old Catalyst if I remember right). I'm almost down to writing my own driver but I must admit that I can't do this from scratch. AMD support wasn't helpful either ("Install the latest drivers.", "Use VGA", etc.)...
Maybe I could fix it if I had access to the driver sources... I doubt that there will be a fix by AMD because the latest legacy driver is dated 2/24/2010 and now we have August
I know that my HW is old but it should be capable of the basic features! And not losing DVI signal when the display is turned off (either manually or display power saver) is a basic feature!!! And by the way, when the Windows power saver turns off my display and I move the mouse the display wakes up again. But there won't be an image anymore ("No signal")?!
If someone of the development staff reads this: I really need help on this and I'm willing to fix it on my own if this is possible, but I can't without knowing why the hell the driver disables the DVI port when the display is turned off!
Awesome, AMD finally dropped support for the legacy Catalyst...
Is there any chance I could gain access to the source code of the legacy driver to get that issue fixed on my own?
