[Linux-ia64] Horrible mouse performance

[Linux-ia64] Horrible mouse performance

[Peter Chubb]

Hi,
	When using the linux 2.5.45+IA64patch kernel on an I2000, the mouse
pointer lags actual mouse movements by a long time, making X almost
unusable.   I haven't configured in the frame buffer, if that makes a
difference.

There certainly are problems with the input layer in 2.5.  So the
keyboard is actually working for you?  That's better than it used to
be! ;-) Both mouse and keyboard are connected via PS/2, not via USB, I
assume?

(I don't normally see such problems because I do most of my 2.5 work
remotely, without console access.)

Yes, this is on an I2000.  I'm trying to see if preemption support
makes any difference.  But the interactive-via-X performance is so
awful anyway, that I can see no difference.

Have you tried using a USB mouse/keyboard?  That seemed to work much better
for me last time I tried.
