This question may not be appropriate for this ML, but I figured I'd give it shot anyway. I have a RADEONHD (HD 2400 Pro) based card which I normally use with the DVI-I port on my TFT. Of course I'm using the radeonhd driver. BTW it's a PCIe card which I can't test in any other machine. And it's the only DVI card which I have. However sometimes, for no apparent reason, the screen blanks for about one second and then comes right back. Sometimes this happens 3 or 4 times in a row and then stops for an indefinite period to then start happening again. Then there are days where I never see the problem at all. I doubt that it's a thermal problem because I've also seen this in winter when the room was cool. It drives me crazy and makes it almost impossible to do any work. If I use the VGA port I don't see this, but the display isn't nearly as crisp and I can see the screen refreshing. I'm wondering whether anyone else has seen this phenomenon? I'm trying to determine whether a) the TFT has a problem on the DVI input b) the card has a problem on the DVI output c) radeonhd still has problems reliably driving the output over DVI or d) the Xorg server gets a twist in its panties and thinks that it has to blank the screen because it saw a timeout (seems unlikely). --- Gary Jennejohn
