Sure.
The old code would assume mouse delta = speed. Of course, this
assumption is valid only as lo

Improve heavy-load behavior -- no jumping pointer.
(BTW, your mouse acceleration proposal [0] doesn't do it at all.)

Hang on, are we actually
Hi,
The current DRM kernel modesetting tree is already taking care to update
the cursor registers and paint it to the screen. Very cool [0].
What I've done today is a shortcut between the kernel input layer and
DRM to update the cursor directly on screen without the X server be
notified always
