Comment 38 for bug 1386534

I have just tested the specially prepared 3.13.11-03131106-generic kernel you gave me,

and the usual error IS THERE. Using the last few new kernels, the typical scenario is this:

        (1) the correct picture is there for 1 or at most 2 seconds

        (2) then the view is wraps around, asif the horisontal synchron position was at the two-third of the lines

        (3) then within additional very fey seconds the screen becomes white, except for the topmost few scan lines

        (4) and again pretty soon, the whole bright area begins to vibrate between bright white and less bright

And as soon as I boot back into an earlier kernel but using the same Ubuntu root partition, then the screen is steady, and I can work, e.g. write this comment.

Many thanks for your help and valuable time,
        Peter.
