Subject: Re: [PATCH] Input: ALPS - Detect trackstick presence for v7 protocol

Hello,

there should no functional changes (e.g. acceleration speed, 
etc.). And if yes, there is probably some side effect which 
should be investigated.

Please can you provide output from dmesg (grep for psmouse or 
input) and also output from lsinput?

That changed acceleration/speed sounds like psmouse fallbacks to 
some ImPS/2 relative protocol and not ALPS...
