spurious mouse clicks

spurious mouse clicks

[Michael Concannon]

I thought it was my imagination at first, but now I have some slightly 
more convincing evidence of what is going on...

With 2.6.13.1 & 2 as I move my mouse around the screen, I get random 
clicks on things the mouse passes.  Seems to happen more often with the 
first move from idle, but in general, it is just totally random...

With 2.6.9-11.EL and 2.6.12.6 (stock kernel.org) I do NOT get this.

Anyone else seeing this?

I would blame the OS/WM/X, as I have recently upgraded to CentOS4, but 
now I have tried a few different kernels in the process of getting a 
stable config for my wireless setup and I am convinced that the only 
variable that seems to matter is the kernel version.  I have had this 
laptop for about a year and prior configs never had any mouse issues.

Config:
2.6.13.1 & 2 from kernel.org .config is the "default" from CentOS 4 - 
happy to post if anyone is interested.
Machine:
    Dell 8600 Pentium M 2GHz 1.5G ram
Mouse:
    touch pad PS/2 - dmesg/proc do not seem to show anything more 
specific than that
    PNP: PS/2 Controller [PNP0303:KBC,PNP0f13:PS2M] at 0x60,0x64 irq 1,12
OS:
    CentOS 4.1 - KDE 3.3 stock config

 Do you have lines like:

psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 1 bytes away.

 in your dmesg?

it would appear not...

oops - I am running 2.6.12.6 now - I guess I should try the offending 
kernel before I answer that question ;-)

BTW - I also neglected to mention that I routinely lower Hz to 250 in 
param.h to remove sound-card whine - but I did this with all kernels in 
question... (it is now a CONFIG option in 2.6.13 which is nice... )

Been using 2.6.13.2 most of the day - and though I have seen fewer 
random clicks - I am still seeing them...

no dmesg output though...  anything else I can check?

Thanks,

Well, it seems that others have run into this as well and that the issue 
might be the result of the introduction of a more specific 
driver/features (for Alps touchpad) which accompanied breakage, er "new 
features", of the more generic driver...

Some embarrassingly slight changes to my google search terms popped up 
this conversation from this summer (I am just waiting for google to 
release the tool that knows what I am looking for before I ask.  Either 
that or the end of civilization which would clearly come if they took 
the old deja-news archives off-line again...):

http://groups.google.com/group/fa.linux.kernel/browse_thread/thread/1af60302c31aa4bf/f0e91763bafea020?lnk=st&q=touchpad+sensitivity+2.6.12&rnum=1#f0e91763bafea020

So, I guess I will have to break down and:

a. read that thread
b. change drivers to the more specific Alps driver... 
c. perhaps tweak some parms to get it to stop interpreting random mouse 
movements as clear statements that I would like to delete files and 
trash my desktop...
