Bug Description

Binary package hint: xorg

If the Emulate3Buttons is on (which it is by default), mouse click are detected with a delay.

Example , try to enlarge a window :
 - point on the windows edge
 - press and hold left mouse button
 - move the mouse

Expected :
 - the window edge is dragged

Actual :
 - as the mouse click is delayed, the system detects the click when the pointer already moved off the window edge. Whatever is under the pointer in this momemt, will be clicked.

Bug known upstream : https://bugs.freedesktop.org/show_bug.cgi?id=1752

Workaround :
Set in xorg.conf in the InputDevice section for the mouse :
 Option "Emulate3Buttons" "false"

I see no reason to enable emulate3buttons in xorg.conf. It's autodetected anyway and autodetection also enables a timeout on move for the 3 button emulation, eliminating this annoying problem.

Could someone take a look at this?

Setting Emulate3Buttons to false no longer fixes this problem in 8.10. I'm guessing this has something to do with evdev.

@paul

Check your X log to see if evdev is being used. I haven't tried 8.10 myself yet.

Btw, fedora 10 uses evdev and has a similar problem. But the delay is only noticable for a few minutes after starting X, then the delay disappears. This might be a bug in evdev if ubuntu has the same problem.

I managed to work around this problem creating an .fdi file in /etc/hal/fdi/policy to set Emulate3Buttons to false for my mouse (similar to how this is done here: http://psung.blogspot.com/2008/09/scrolling-with-thinkpads-trackpoint-in.html)

However, this workaround shouldn't be necessary. xorg knows that my mouse has 3 buttons (the log states so), therefore it should automatically set Emulate3Buttons to false in this situation.

I don't know anything about HAL or the .fdi files (there appears to be no documentation anywhere). Is it possible to detect 3 mouse buttons and change the Emulate3Buttons setting purely through .fdi files? Or, are changes to code necessary - if so, which code would need to be changed?

I have two mouse-like devices on my system, a logitech mouse and a FingerWorks iGesture pad.

Both of these worked great under Ubuntu 7.04. This weekend I upgraded to 8.10, and now the iGesture pad has trouble with click and drag. I have tried adjusting drag threshold and so forth, but still I have to wait 1/2 second after 'clicking' with the iGesture pad before I can move it to make a selection.

This problem exists always, no matter how long the system has been running.

my Xorg.0.log file shows that evdev is being used, but it says it only detects 1 mouse button on the iGesture pad. I'm sorry I do not know what it used to detect under 7.04

I've attached my Xorg.0.log

look at this part:

(II) config/hal: Adding input device FingerWorks iGesture Pad USB
(**) FingerWorks iGesture Pad USB: always reports core events
(**) FingerWorks iGesture Pad USB: Device: "/dev/input/event5"
(II) FingerWorks iGesture Pad USB: Found x and y relative axes

but hmm, xinput says:

"FingerWorks iGesture Pad USB" id=10 [XExtensionPointer]
 Num_buttons is 32
 Num_axes is 2

(32 buttons, not 1)

The workaround for the click delay in Intrepid:

1. Execute
xinput list
and note your mouse name. For me, this is "Logitech USB-PS/2 Optical Mouse".

2. Create the file /etc/hal/fdi/policy/mouse-3button.fdi, containing (replace the mouse name with yours!):
<match key="info.product" string="Logitech USB-PS/2 Optical Mouse">
 <merge key="input.x11_options.Emulate3Buttons" type="string">false</merge>
</match>

3. Unplug your mouse and replug it. (This won't suffice if it's a PS/2 mouse i guess. In this case reboot.)

Still in 8.10 with all the latest auto-updates.

I'm not sure what the internals are like in this, but it seems that such a "delay" means that (at least certain) mouse events are not being delivered accurately to the system or app. I think this is more serious than a simple UI annoyance as it introduces indeterminancy where there should be none (and probably did not exist prior to bug). That is, if the mouse button went down at one point, the app should not have to wait for the system to provide it with some sampled coordinates at an arbitrary later time.

Given that people have found a work around by disabling the Emulate3Buttons opoeution, does it mean that for those who do use or need Emulate3Buttons, this bug remains a problem?

See attached screenshot for the same behavior with the RMB on window title bars.

Sounds like the default mode of having 3rd button emulation mode on "auto",
in which case it's disabled the first time an actual third (middle) button
is pressed, but until then it has to wait for the timeout on presses of
either button 1 (left) or button 2 (right) to see if you'll hit the other
one fast enough to trigger the button 3 emulation.

You should be able to "fix" by changing the configuration of mice that
actually have 3 buttons to disable 3rd button emulation, though I'm not
up-to-date on how to do that with udev/evdev.

Alan is right, the option you're looking for is Option "Emulate3Buttons" "off", see evdev(4) for more info. Configuration instructions are on https://fedoraproject.org/wiki/Input_device_configuration

in your fdi file, add an x11_options for the above option, example from the fedora wiki site:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="input.touchpad">
        <merge key="input.x11_driver" type="string">synaptics</merge>
        <merge key="input.x11_options.TapButton1" type="string">1</merge>
    </match>
  </device>
</deviceinfo>

then restart HAL, make sure that lshal shows the option and then restart X.

uhm, yes. in 1.8, not in 1.7. AFAIK Ubuntu and Debian have some partial udev
backport, I don't quite know which bits apply and which ones dont. check
x11_input.rules or so in the udev files.

well, that's the theory but IIRC for usb mice that field is always set,
curtesy of the PS/2 protocol not allowing any button detection.

it's one more of these things that should just have a checkbox in the GUI
instead of relying on unreliable autodetection...

we're getting that data from the kernel though. the kernel sets those based
on the HID protocol descriptors but for older mice (though arguably those
don't matter much anymore) it's the PS/2 protocol. and that doesn't have a
detection mechanism so the kernel always sets those bits (link below, line 568).

so evdev will always think there's a 3+ button mouse because that's what the
kernel tells us. Now, the interesting thing would be what happens for
2-button USB mice - I don't actually know and I don't think I've got such a
device available to me.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/input/mouse/psmouse-base.c;h=979c50215282025fef1c7fa795a6bf20fedfcad4;hb=HEAD

Hm, damn.

USB mice are a lot smarter but I am not sure if the kernel takes advantage of that. It looks like this code was just setting every mouse to have 3 buttons:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/hid/usbhid/usbmouse.c#l180

 180 input_dev->keybit[BIT_WORD(BTN_MOUSE)] = BIT_MASK(BTN_LEFT) |
 181 BIT_MASK(BTN_RIGHT) | BIT_MASK(BTN_MIDDLE);

Anyway, I think 2-button USB mice are so rare that they can be ignored. 2-button touchpads in laptops are common, but they are all PS2 as far as I have seen.

Could we default Emulate3Buttons to off for USB mice, then?

on debian we've ended up backporting the whole udev+inputclass work from
1.8 (except for the NIDR api break). i'm not sure anymore what ubuntu
10.4 ended up shipping with, but i think something like the following in
xorg.conf should work:

Section "InputClass"
        Identifier "3 buttons"
        MatchIsPointer "on"
        MatchVendor "Logitech"
        Option "Emulate3Buttons" "off"
EndSection

This bug was actually fixed as a side effect of the Ubuntu installer not generating an xorg.conf anymore and letting X autodetect the hardware on startup instead. X by default does not enable the Emulate3Buttons flag (I speculate having this flag enabled in the default xorg.conf file was an Ubuntu-specific "feature"), so the problem is gone. I believe this "fix" first occurred in Jaunty, and the first LTS version that has it is Lucid. However, I also believe the Ubuntu upgrader keeps the old xorg.conf file, so merely upgrading to a current version won't make this problem (or the Emulate3Buttons flag that causes it) go away - this can only be accomplished by editing xorg.conf or by installing the current version from scratch.

Yes, my second post corrects the first. The fact that you're getting the problem at all (I presume you're using Maverick?) pretty much confirms Jakob Unterwurzacher's post of 2010-09-14 for the case of Maverick, so we now know that "fix committed" is still the correct status. What I don't fully understand is by what mechanism the importance was changed from "Low" to "Unknown".

Also, that option in your xorg.conf should prevent the problem from occurring at all, no matter what X version you're using, so something doesn't make sense here. I think you *might* have used incorrect syntax in your xorg.conf, where the correct syntax would be (note not only the section but also "off" instead of "no"):

Section "InputClass"
        Option "Emulate3Buttons" "off"

I am running lucid (10.04.1), not maverick.

The Emulate3Buttons option is in an InputDevice section, not InputClass. I do not know if that matters.

man page for xorg.conf says:

the following boolean option values are recognised as FALSE:

           0, off, false, no

So I think I'm ok using "no" instead of "off".
