Touchpad Quirks for Sony Vaio VPCEG Series Laptops (2011 Model)
Here are the contents of the quirks file I have been using for about a year on 2 different Sony VPCEG Series laptops. These laptops use a Synaptics touch pad. There are many VPCEG Series laptops but my research shows that the core hardware is the same (touchpad, screen, processor etc). The file was created to match all VPCEG Series laptops. The only change is the touchpad pressure.
[Touchpad pressure override]
MatchUdevType=touchpad
MatchName=*SynPS/2 Synaptics TouchPad
MatchDMIModalias=dmi:*svnSonyCorporation:pnVPCEG*
AttrPressureRange=45:40
My current version of libinput is 1.15.5-1
There is a hardware issue with this touchpad that causes a jump when the primary finger moves off the edge. I was able to fix that in the Kernel, but it is a hack and the computer is old so I'll manage that on my own. Details can be found in Issue #258 (closed)
Thank you!!!
