I wonder if there is more to this problem than meets the eye. We have reports from the schools and sightings from volunteers that there are more laptops with this problem out in the field, and more reports keep trickling in. We expect to have our hands on another 5-10 cases soon. Thanks, Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Fuzzy screen problem in Nicaragua
We've seen a handful of XOs with an interesting problem here. There is a large vertical stripe of fuzzyness on the left side of the screen. It seems to be in the same place on every XO that we've seen. It is not always obvious. For example, on the static-white OFW background, it is completely invisible. But move into the OFW disk block view and you can clearly see the fuzzyness. It seems to be a problem within the display. Moving the affected display to a different XO causes the problem to appear there, and taking a known-good screen and putting it in the affected XO makes the problem go away. Here is a video where you can see the problem clearly: http://dev.laptop.org/~dsd/20100129/fuzzy-screen.mpg (14mb) Is this a known/recognised problem? Any solutions or diagnosis available? cheers Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
