RE: Jittery PS/2 Mouse in 7.0-RELEASE

I believe if you run the mouse daemon and use /dev/sysmouse
in xorg it will work a lot better.

 Subject: Jittery PS/2 Mouse in 7.0-RELEASE


 I have a PS/2, wired, optical mouse that I have been using flawlessly with
 Windows and several Linux distributions for years now.  I would like to
 switch
 to Free BSD, but the mouse becomes very jittery within FreeBSD.  I have
 tried
 the mouse with both moused and X controlling the mouse, but in both cases
 the
 result is the same. The cursor on the screen tracks properly when
 I move my
 mouse in a wide arc, but when I move the mouse in small increments the
 cursor
 does not follow the mouse at all.  This makes it very difficult
 to click on
 small targets such as an OK button.

 Relevant Information:

 uname -a output:
 FreeBSD kienjakenobi 7.0-RELEASE FreeBSD 7.0-RELEASE #3: Sun Mar

 dmesg mouse output:
 psm0: PS/2 Mouse irq 12 on atkbdc0
 psm0: [GIANT-LOCKED]
 psm0: [ITHREAD]
 psm0: model IntelliMouse, device ID 3

 xorg.conf:
 Section InputDevice
 Identifier Mouse0
 Driver mouse
 Option Protocol PS/2
 Option Device /dev/psm0
 Option Emulate3Buttons no
 Option ZAxisMapping 4 5
 EndSection

 This does not seem to be a problem with X for several reasons.
 First, I use
 this version of X.org with Linux with the same config that is shown above
 without this problem.
 Second, when I give control of the mouse over to moused, the problem does
 not
 change.  It is visible even in the console when using moused.

 I am using a custom kernel, but this problem does not change even
 when I am
 using the GENERIC kernel.

 Based on this information I think I have crossed out most potentional
 porblem locations,
 but I hope I missed something.

Which kernel scheduler are you using? I had very similar symptoms on early
versions of 7 with the default SCHED_BSD. Switching to SCHED_ULE resulted
in a marked improvement.
