Bug 336658 – x11-drivers/xf86-input-synaptics-1.3.0 pointer acceleration

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description pierre 2010-09-10 00:05:38 UTC]

hi.
I'm not sure this is a gentoo bug...
I've installed today last x11-drivers/xf86-input-synaptics-1.3.0
it compile well, X starts without any warning, works fine except there is no pointer acceleration : a whole touchpad slide only moves pointer of half an inch on the screen.
I'm running xfce and xorg-server-1.8.2. changing xfce settings doesn't work.
back to x11-drivers/xf86-input-synaptics-1.2.2-r2 and everything works fine again.
I can provide more infos if needed

Please attach your Xorg.0.log and all relevant configuration files (xorg.conf, HAL fdi files, etc).

Thanks

no HAL.

Xorg.0.log diffs are (except version numbers)

SynapticsMouse1: finger width range 0 - 0            # in both
SynapticsMouse1: invalid finger width range.  defaulting to 0 - 16      # in new 1.3.0


and later, 1.2.2-r2 says :
SynapticsMouse1: always reports core events
(II) XINPUT: Adding extended input device "SynapticsMouse1" (type: TOUCHPAD)
(**) SynapticsMouse1: (accel) keeping acceleration scheme 1
(**) SynapticsMouse1: (accel) acceleration profile 0
(**) SynapticsMouse1: (accel) acceleration factor: 2.000
(**) SynapticsMouse1: (accel) acceleration threshold: 4

while 1.3.0 says :
(**) SynapticsMouse1: always reports core events
(II) XINPUT: Adding extended input device "SynapticsMouse1" (type: TOUCHPAD)
(**) SynapticsMouse1: (accel) MinSpeed is now constant deceleration 16.7
(**) SynapticsMouse1: MaxSpeed is now 2.00
(**) SynapticsMouse1: AccelFactor is now 0.001
(**) SynapticsMouse1: (accel) keeping acceleration scheme 1
(**) SynapticsMouse1: (accel) acceleration profile 1
(**) SynapticsMouse1: (accel) acceleration factor: 2.000
(**) SynapticsMouse1: (accel) acceleration threshold: 4

[Comment 4 pierre 2010-09-11 00:41:11 UTC]

with 1.3.0, changing my xorg.conf settings for :

Option "MaxSpeed"       "0.32"
and
Option "AccelFactor" "1.1010"

gives in log :
MaxSpeed is now 5.33
AccelFactor is now 1.101

and the pointer behaves plus or minus like with 1.2.2-r2

[Comment 5 Rémi Cardona (RETIRED) 2010-09-11 07:23:15 UTC]

I still need the Xorg.0.log.

Thanks
