On a Toshiba NB205 netbook with Intel graphics, 32-bit LXDE, the cursor speed is perhaps half or one-third what it was before the xserver-xorg update this morning.  I am posting to find out if it is only my system, in which case I can go into xset and adjust it, or whether it is a more general issue that might be a bug.  Anyone else?


Edit: I started to troubleshoot this issue today, and I eventually discovered that things have changed, wrt mouse acceleration.  The settings in /etc/xdg/lxsession/LXDE/desktop.conf, as well as ~/.config/lxsession/LXDE/desktop.conf, are not working as they have in the past, and I don't think xset is finding correct values either.  I'm out of time to chase it further today, but tomorrow I will make study here.

There was a user on IRC last night witrh the same problem with a Thinkpad W520. He discribes the touchpad as being slow and "feeling all wrong". I tried to find a cloue to this and what I came up with was acpi-support-base, which has dropped a lot of config.files. That was as far as we got. The output during the install of the package was:
Code: [Select]

No idea if this plays into it or it is just a coincidence. My Thinkpad T540p touchpad is unaltered.

Interesting -- I would not have thought of acpi as relevant to mouse acceleration, but then maybe so.

A little more troubleshooting today.  The same issue exists on a Dell Latitude E6500, 64-bit KDE, but only with the touchpad, not with the pointing stick.  I booted the Toshiba with a USB serial mouse, and the mouse works perfectly.  I booted the Dell with the same USB serial mouse, and it works perfectly.  So the problem is limited to the touchpads on both those machines.

Next, I checked what hardware was found under /proc/bus/input/devices, and this is where I found something interesting.  Here are the relevant details:

Notice the final Alps PS/2 device is identical in both machines that have the problem.  So I think the Alps device driver may be the culprit, but I don't know anything about it -- whether it is a built-in kernel module or how it works.  For the Toshiba, dmesg shows this:


Code: [Select]
[    5.841338] input: ALPS PS/2 Device as /devices/platform/i8042/serio1/input/input12
[    5.888876] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input8


I think there's a bug, but I don't know which package to file against.  Any idea?


EDIT: It looks like the fedora devs are aware of it and have a working patch for it now -- see comments 35 - 44 on that thread.  It is a bug in the fedora package named xorg-x11-xserver-xxx --  but the debian xserver packages are named differently.  So apparently it did come from the xserver-xorg update yesterday.

Hi there.

I have the exact same issue with my Lenovo Ideapad N580 running Debian/Unstable. Package is (I'm almost certain) xserver-xorg-input-synaptics, but I haven't had time to investigate this.

Glad to know it's not my hardware all-of-a-sudden.
Cheers.

I seem not to have this trouble on my Compaq 615 laptop.
But I seem to have another type of touchpad and another driver and therfore it might work here.
I have:
SynPS/2 Synaptics TouchPad

That sounds right to me, too.  There is a newer version of that package in the experimental repo, which I thought would be worth a try, however:


Code: [Select]
root@tosh205:/# apt-get install -t experimental xserver-xorg-input-synaptics
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:


The following packages have unmet dependencies:
 xserver-xorg-input-synaptics : Depends: xorg-input-abi-20 but it is not installable
E: Unable to correct problems, you have held broken packages.


So I guess we'll have to live with the issue for awhile.  According to Debian Packages, xorg-input-abi-20 is a virtual package that contains xserver-xorg-core and xserver-xorg-core-udeb.  According to apt, it is so virtual that it does not actually exist.   ;D

Kind of solved it by setting MinSpeed = MaxSpeed = 1 in my /etc/X11/xorg.conf/synaptics.conf.

Hint from http://xorg.freedesktop.org/wiki/Development/Documentation/PointerAccelerationAsOf16/
(last section)

The speed is now better, although acceleration is not quite right. Might have to tweak a bit.

Cheers.

Interesting.  I don't have synaptics installed, and it does not appear that a package is available in sid.  What version are you using?

# dpkg -l|grep synap
ii  xserver-xorg-input-synaptics          1.7.3-1+b2                        amd64        Synaptics TouchPad driver for X.Org server

(Note, this is debian/unstable, not siduction).

I made a synaptics.conf to disable an annoying involuntary middle-click:

# cat /etc/X11/xorg.conf.d/synaptics.conf
Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "-1"
        Option "TapButton3" "-1"

        Option "MinSpeed" "1"
        Option "MaxSpeed" "2"
        Option "AccelFactor" "0.5"
EndSection

With the MinSpeed, MaxSpeed and AccelFactor (note that Min and Max do not need to be the same, with the settings above it works wonderfully. I don't know why, but the problem is gone -- without any upgrade/dist-upgrade in between).

So it could be that by manually setting non-default options the new "broken" acceleration scheme is disabled.
For all I care I'm a happy penguin again :)

Hi, I have the same behavior on a Dell M4500. Now, I can't find xorg.conf.d ..


The bizarre thing is two-finger scrolling on the touchpad (AlpsPS/2 ALPS DualPoint) has the right acceleration.

I either give too many fucks or no fucks at all, it's like I cannot find a middle ground for a moderate fuck distribution, it's like what the fuck

But, what is this /etc/X11/xorg.conf.d/synaptics.conf file?

LOL :) A long long time ago you could not even run X without a config (XF86Config, then xorg.conf).
Nowadays X(org) runs fine without config thanks to udev and general Linux-modern-ness :) but that doesn't mean you don't have to tweak here and there.

X will read/honor /etc/X11/xorg.conf if exists as well as any conf files dropped in /etc/X11/xorg.conf.d.
I use it to tweak my synaptics touchpad as well as to set SNA as default acceleration method for the Intel graphics card (perhaps it's already default, but it doesn't hurt).

I made a synaptics.conf to disable an annoying involuntary middle-click:

# cat /etc/X11/xorg.conf.d/synaptics.conf
Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "-1"
        Option "TapButton3" "-1"

        Option "MinSpeed" "1"
        Option "MaxSpeed" "2"
        Option "AccelFactor" "0.5"
EndSection

With the MinSpeed, MaxSpeed and AccelFactor (note that Min and Max do not need to be the same, with the settings above it works wonderfully. I don't know why, but the problem is gone -- without any upgrade/dist-upgrade in between).

So it could be that by manually setting non-default options the new "broken" acceleration scheme is disabled.
For all I care I'm a happy penguin again :)


I made this /etc/X11/xorg.conf.d/synaptics.conf file, ran d-u, and then rebooted.  Voila!  It is a big improvement -- pretty close to what the mouse acceleration was prior to the breakage.  Thank you very much for this solution!  I am going to mark the topic "Worked Around", since I think that is what we have here.


The remaining drama being, I wonder what will happen if & when the bug is fixed in the driver?  If my ~/.config/lxsession/LXDE/desktop.conf file once again functions correctly, I may have to revert this workaround.  But for now, it is good.
