RE: Laptop Mouse Weirdness



Jeff:

Let me see if I understand you correctly.  When you put the IMPS/2
protocol onto the /dev/psaux port as defined by the link you provided
below, then your built-in mouse starts screwing up but the external
mouse works fine.  And when you change the mouse protocol for /dev/psaux
to PS/2, the built-in mouse works but the scroll buttons don't.

I did notice one possible problem with the configuration is that
"Emulate3Buttons" is turned on and you cannot do this with a wheel mouse
or, I'll guess, a built-in wheel mouse.  I'd try removing the 3-button
emulation first before the protocol.

Let me know what happens.


Dave

David,

	Thanks for your reply, my laptop has 2 scroll buttons, that are
supposed to work like the wheel.  they work in Windows, and I've read
from a few write ups on linux-laptop.net that you just need to configure
them as a wheel mouse with the Zaxis mapping.

http://mobilix.org/toshiba_sp4600.html#ToC13

But anytime I try to use the IMPS/2 protocol the pointer freaks out.

I'll have to give a USB mouse a try, I found a P2/2 to USB mouse adapter
and tried using a old (never meant to be used with USB) PS/2 mouse and I
couldn't get it to show up at all on the system.  Are USB capable PS/2
mice different than a standard PS/2 mouse?

This probably isn't the right place for the next question, but if I'm
going out to buy a mouse, will I be able to utilize all the buttons that
are on some mice, or should I stick with a 2 button wheel mouse?
