2.6.0-test11 ps2 mouse giving corrupt data?

2.6.0-test11 ps2 mouse giving corrupt data?

[Andrew Walrond]

I have just switched from l2.4 to 2.6 on my thinkpad, and the mouse does 
something wierd when I boot into x (kde)

startx, then wait for everything to load, then move mouse. Mouse goes crazy, 
menus pop up everywhere as though I were pressing buttons, and after about 3 
seconds, it all settles down and works perfectly.

So whats causing this? I 've read about the mouse detection stuff in recent 
2.6 giving incorrect resolutions and stuff, but thats doesn't apply here. Its 
getting a load of bad data.

A buffer_len load of crud is being provided before the real stuff arrives 
perhaps?

PS For 'mouse' read 'Little Red Nipple' which AFAIK is just a ps2 mouse as far 
as linux is concerned. Worked for 2.4 anyway.

Most likely X does something nasty to the keyboard controller while it
is starting up. The psmouse kernel driver has an autosync feature which
can get it out of trouble if you don't move the mouse for two seconds.

When did the autosync feature arrive?
It doesn't work for me(k2.6.11 with
MSI K7N2 Delta nforce2 mboard
and k2.6.11 with Shuttle Xpc SK41G
FX41 mboard with VIA fsb) if ps2
kvm switch(Belkin) is switched away.

When sync is lost on my pc's I have to
reboot. Symptoms are the same, on X or
text term--any mouse movement triggers
selects and buttons down but the correct
events do not occur.

With a kvm switch k-2.6.? loses psmouse
sync on the off pc. Rebooting is the only
solution. I got tired of this and moved the
mouse(logitech trackman fx) to one pc,
so the other only has to boot with the
mouse attached either to kvm or ps2
port on pc. That's fine until moving the
mouse back and forth for rebooting
causes the pc with X running to lose
sync. Then it can't regain sync.

2.5.something.

Now when your Belkin switch resets the mouse, the autosync will not
work, as it only compensates for lost bytes, not a complete protocol
change. Use 'psmouse_noext" on the kernel command line to disable wheel
handling and it'll work OK.

(Automatic mouse reinitialization is on the planned feature list.)
