[SOLVED] After update to xorg-server 1.16.0-5 touchpad not working

After today's xorg update ( [PACMAN] upgraded xorg-server (1.15.2-1 -> 1.16.0-5) and related package updates for xf86* my laptop fails to have a working touchpad.

$ synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?

There seems to be some diagnostics in the Xorg.log.0 file:

[     4.637] (II) LoadModule: "synaptics"
[     4.637] (II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so
[     4.638] (II) Module synaptics: vendor="X.Org Foundation"
[     4.638]    compiled for 1.15.1, module version = 1.8.0
[     4.638]    Module class: X.Org XInput Driver
[     4.638]    ABI class: X.Org XInput driver, version 20.0
[     4.638] (EE) module ABI major version (20) doesn't match the server's version (21)
[     4.638] (II) UnloadModule: "synaptics"
[     4.638] (II) Unloading synaptics
[     4.638] (EE) Failed to load module "synaptics" (module requirement mismatch, 0)
[     4.638] (EE) No input driver matching `synaptics'

The only change that I made after today's updates was to move the pacsave file for 10-evdev.conf that was changed during the update in /etx/X11/xorg.conf.d/

I have an existing /etc/X11/xorg.conf.d/50-synaptics.conf that was there from before the update, and there is no similarly named file in /usr/share/X11/xorg.conf.d/

Can anyone point me to a fix?

Thanks

Edit:  I checked the list of packages updated and it does not include xf86-input-synaptics - so I guess that the current version is not compiled against the current xorg-server - maybe I should file a flyspray bug report?

I also checked the last update on my system for

[2014-06-01 20:09] [PACMAN] upgraded xf86-input-synaptics (1.8.0-1 -> 1.8.0-2)

and also found a previous bug report from just over a month ago concerning synaptics but I am unsure what the current situation is:

There should be an update today: https://www.archlinux.org/packages/extr … synaptics/

I have no problems with my touchpad.

I think the update has swiped your 50-synaptics.conf from the folder. After the Update pacman tells that the config files also can be stored under the homedir of an user.

Re: [SOLVED] After update to xorg-server 1.16.0-5 touchpad not working

Thanks - on that page I saw that "Last Updated:    2014-07-29 10:10 UTC" but I didn't see any new version in [testing] - hopefully an updated package will bring back a working touchpad for me and anyone else who has the same issue.

The key underlying issue seems to be that the new xf86-input-synaptics package has listed

X-ABI-XINPUT_VERSION=21 (xorg-server) (make)

but needs to be released to the mirrors - in the Xorg log that I put in the original post the crucial line is I think

[     4.638] (EE) module ABI major version (20) doesn't match the server's version (21)

Yet the ABI version listed in the package is correct for the new version for when it gets released.

I have the file in what seems to be the correct place:

$ ll /etc/X11/xorg.conf.d/
total 20
-rw-r--r-- 1 root root 1160 Jul 29 15:17 10-evdev.conf
-rw-r--r-- 1 root root 1160 Mar 13 21:52 10-evdev.conf.pacsave
-rw-r--r-- 1 root root  142 Dec 28  2013 50-joystick.conf
-rw-r--r-- 1 root root 2290 May 19 22:06 50-synaptics.conf
-rw-r--r-- 1 root root  115 Dec 28  2013 50-vmmouse.conf

Could you check the contents of your files? I mean pacman copies the old config files to xyz.pacsave and replaces the with the new ones.

Re: [SOLVED] After update to xorg-server 1.16.0-5 touchpad not working

I found that the xf86-input-synaptics package in extra had exactly the same version number as it was when I last updated it on my system using the version that was in the aur at the beginning of June.

xf86-input-synaptics 1.8.0-2

Hence the pacman -Syu today did not include this package in the updates since the version from extra currently lists as dated 18th July also has this version number.

So I removed the package file from the pacman cache and reinstalled xf86-input-synaptics - and my touchpad is now fine. So this was primarily my fault for not using the standard package but an aur package with the same version number. I will mark this as solved. So it is not a bug after all.
