Subject: g-i: Use different pixel threshold for d-i and desktop

d-i doesn't have any clockish thing, and its text interface doesn't
change much while progressing, thus needing a small threshold

The LXDE desktop, on the other hand, has by default a CPU meter and
clock, which needs a bigger threshold.
