On Fedora 17 and 18 I sometimes get a display like nothing else I
know. It's made up of short horizontal lines, some in color, arranged
into long diagonals that cover the screen, with about the angle of a
backslash. The little lines in each group are parallel, and there's
always a little space between every group and the next.
It comes up suddenly, on a key press or a mouse click.
Once it comes up, it owns the machine -- nothing the mouse or
keyboard can do (that I know of, anyway) has any effect, and I have to
hit the reset button.
I have yet to discover any correlation with any user action :
afaict, some power of darkness arms the trigger, apparently randomly, and
the next thing I do brings on the crash.
Has anyone else seen this? Diagnosed it? Found any prevention or
cure??
