Greg,
Jonathan mentions "
By "slow" I mean there is a lot of latency. The cursor can move fast; the
cursor moves straight to anywhere I touch. But there is a noticable delay
between touching and cursor movement. If I drag the stylus across the
screen, the cursor is a few mm behind. "
I saw the same behavior using tslib.
Using TSLIB there will be a cursor (I think tslib draws the cursor), while
using the old interface, there is not such cursor. So I cannot compare the
two.
However, one problem using this patch is that, using "top" I saw nano-x
using 99% of CPU, So it looks there is some issue with this patch.
