Hi Please re-assign to linux-image-3.2.0-2-amd64 as this should be the correct package - sorry about wrong uname usage on my side while running report-bug. On topic: I've tested it again and it does only seem to happen on my laptop, when I have a secondary display enabled (VGA). If I switch to a single display prior to locking the screen with xrandr, then the problem will not occur. Does this help? Cheers Carsten
