Synaptics Overriding Settings

After updating, it seems the new synaptics driver isn't respecting the settings I have in /etc/X11/xorg.conf.d/10-synaptics.conf.

10-synaptics.conf:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "0"
        Option "TapButton2" "0"
        Option "TapButton3" "3"
	Option "PalmDetect" "1"
	Option "HorizTwoFingerScroll" "1"
	Option "MaxSpeed" "3"
	Option "AccelFactor" "0.20"
	Option "SHMConfig" "on"
	Option "CoastingSpeed" "0"
EndSection

cat /var/log/Xorg.0.log | grep synaptics:

[     4.219] (--) synaptics: bcm5974: touchpad found

Additionally, the driver is terribly picky about multiple fingers, meaning it's very hard to right click (two finger) or middle click (three finger) on my macbook pro 7,1 touchpad. It wasn't before the update, when I had 1.5.0-something.

Help? sad In the meantime, I can override settings by running synclient MaxSpeed=3 at login, but it sucks to have it broken and right/middle click are still basically impossible.

Thanks!

Re: Synaptics Overriding Settings

I'm having similar issues.  For example, after restarting the X server,

$ cat /etc/X11/xorg.conf.d/10-synaptics.conf | grep -iw maxspeed 
	Option "MaxSpeed" "27"
$ synclient -l | grep -iw maxspeed
MaxSpeed                = 90

For some reason it keeps resetting to some crazy value for MaxSpeed.

Re: Synaptics Overriding Settings

A temporary fix was to downgrade everything to the following versions:

xf86-input-evdev 2.6.0-4
xf86-input-synaptics 1.5.0-1
xf86-video-nouveau 0.0.16_git20120106-1
xorg-luit 1.1.0-3
xorg-xkbcomp 1.2.3-1
xorg-setxkbmap 1.2.0-3
xorg-server-common 1.11.4-1
xorg-server 1.11.4-1
xorg-util-macros 1.16.2-1
xorg-server-devel 1.11.4-1
xorg-xauth 1.0.6-1
xorg-xgamma 1.0.4-3
xorg-xhost 1.0.4-3
xorg-xinput 1.5.3-2
xorg-xlsatoms 1.1.0-3
xorg-xmodmap 1.0.5-3

However, this is an ugly cover-up; the issue is still unresolved.

Re: Synaptics Overriding Settings

Is it synaptics or the device driver in the kernel, do you think? I ask because I still get a maximum speed of 1.75 and two finger tapping still works OK. (Less sure about three finger because I use it less and always find that a bit hit and miss.) According to the manual page, synaptics takes defaults from the in-kernel device driver...

Note that I don't configure through an xorg config fragment but via a script in my home directory so that would still work anyway but I don't set the maximum speed at all - so 1.75 is just the default I'm getting.

Re: Synaptics Overriding Settings

If anybody else is having this problem and doesn't want to downgrade, I hacked together a quick bash script to extract the options from xx-synaptics.conf, turn them into the appropriate synclient commands, and output those commands to a new script.  I currently have xfce autorunning the synclient commands.  I just thought I'd share -- RUN THIS AT YOUR OWN RISK, and of course change the paths/files to fit your system and your liking.

I am pretty new at scripting, but this appears to be working.  Edited to add:  This assumes that the input config file contains only options for synaptics.  It won't work if, say, you have your synaptics config lumped with with xorg.conf.

$ cat /usr/local/bin/scripts/extract_opts 
#!/bin/bash

if [ "$(id -u)" -ne "0" ]; then
    echo "This must be run as root"
    exit 1
fi

syn_file="/etc/X11/xorg.conf.d/10-synaptics.conf"
output_file=/usr/local/bin/scripts/set_tpadopts
syn=`which synclient`

echo "#!/bin/bash" >$output_file
chmod +x $output_file

if [ -f $syn_file ]
then
    while read line; 
    do
	echo $line | sed -n "s:Option \"\([a-zA-Z0-9]*\)\" \"\(.*\)\":$syn \1=\2:p" >> $output_file
    done  < $syn_file
else
    echo "Nonexistant xorg config file $syn_file"
    exit 1
fi

This creates a second script designed to be run sometime during DE startup:

This really isn't a solution, but I preferred doing this than dealing with downgrades until the bug is fixed.  Heck, I'm not even sure which package has the bug at the moment or I'd file a report.

Re: Synaptics Overriding Settings

The most recent synaptics (1.5.99.904-1) has some other annoying problems:

For example while dragging the mouse pointer pressing the left touchpad button doesn't do anything. So when I want to select text I need to not touch the touchpad surface, then click the button, then select the text with the touchpad.

The tap-clicking feels not right too.

Re: Synaptics Overriding Settings

I'm not sure, but given that the behavior was fixed when I downgraded synaptics, I'm guessing it's not the kernel driver? I think it was setting MaxSpeed to the device's possible erported MaxSpeed (just a guess). I tried using a script like Feynman suggested, but the mouse pointer (unreported above) would still frequently disappear on suspend/resume or when it was in the mood to do so, and so downgrading seemed the only option.

Yeah, dragging was sad too... and since I don't have a button separate from the touchpad surface (macbook pro), blurgh. Downgrading has made me a happy clam, though.

Re: Synaptics Overriding Settings

I just upgraded to xf86-input-synaptics-git from AUR.

It just didn't include a proper /etc/X11/xorg.conf.d/10-synaptics.conf so I just copied the example.

Now the touchpad works well again.

I'm glad that it fixed your issue CDH, but upgrading to xf86-synaptics-git didn't work for me.  I copied the section to ignore duplicates with MatchDevicePath "/dev/input/mouse*" with no improvement.  Here is my current synaptics.conf:

The synaptics archwiki Gnome section https://wiki.archlinux.org/index.php/To … tics#GNOME indicated that Gnome may try to override some settings.  I'm using Xfce instead of gnome, but the behavior sounds similar.  I'll try to disable Xfce's mouse settings program (not sure how to do that yet..) and see what happens.

Re: Synaptics Overriding Settings

Maybe we don't have the same issues...

(I am wondering, is X no still trying to load a file named original.10-synaptics.conf?)

In the git version there have been multiple issues fixed for me: Coasting works as expected again, clicking with the touchpad keys while dragging the mouse pointer works correctly and generally the touchpad_kcm control for kde works again, many parts of it wouldn't work with current synaptics, and the sensitivity has been fixed (I believe the tap-clicks feeling not right was due to too high sensitivity.). But maybe there are still unresolved issues.

Oops, I didn't mean to post that typo from my terminal (editing it out now), but in case that was the issue. I've moved those files in and out and restarted X with no change

Re: Synaptics Overriding Settings

I have a notebook HP dm4 and I had the same issue with my synaptic touchpad. After a lot of reading I realized that Xorg has new features, one of them is the  Pointer Acceleration. It basically try to set a correct velocity and acceleration for our pointer but it seems that synaptics try to do the same, resulting in a very weird behavior.

I didn't downgrade, what I did to solve this issue was comment MaxSpeed, MinSpeed and AccelFactor and choose my prefered acceleration profile and play with the ConstantDeceleration until I got a responsive pointer. I'm currently using xf86-input-synaptics 1.6.2-1.

Here is my final 10-synaptics.conf:

Re: Synaptics Overriding Settings

satanas, there have been quite a few xorg-input-synaptics updates since this thread was last active.  So I suspect that the problem you were having is probably unrelated to the issue discussed here.


Edit:  BTW, welcome to the forums!

WonderWoofy, I'm pretty sure that xorg-input-synaptics has had lot of changes since then but there are two reasons that made me post the reply: 1) My symptoms were exactly the same and 2) this is an issue that can pass unnoticed if you don't touch the MaxSpeed and MinSpeed values at your 10-synaptics.conf.

I thought that my post could help to clarify the reason of why synaptics is overriding settings. That's it wink

Oh! and thanks for the welcome smile
