[gentoo-user] xorg can't work with hotplugged mice?

[Iain Buchanan]

Hi all,

from time to time I remove mice and plug them in, as I move my laptop
around locations.  Sometimes I also start my laptop without a mouse
plugged in, and then plug one in after boot.

But every time I do so, X doesn't recognise the "new" mouse.  I
have /dev/input/mouse[0-3] set up in /etc/X11/xorg.conf.

I have to either restart X, or (this is interesting): switch to a
console, unplug then replug the mouse, then switch back to X, and
allofasudden the mouse works again.

I can't use the generic /dev/input/mice, (the one-for-all device)
because I have a synaptic driver for the touchpad (/dev/input/mouse1),
and "auto" for any other mouse plugged in (/dev/input/mouse2).

Now, the fact that switching to a console and re-plugging the mouse
works is strange - this tells me that X "can" do it without restarting,
but I don't know how to make it recognise the mouse...

I can't (and don't want to) use custom udev rules for two reasons:
1. I want to plug in any mouse and have it used straight away
as /dev/input/mouse2
2. This is such a simple problem, and udev seems like such a complicated
solution :)

And lastly, if I have X running with a working usb mouse
(/dev/input/mouse2), and then unplug the mouse, then /dev/input/mouse2
stays there.  Until I restart X or switch to a console and back (then it
disappears)... strange!!

does _anyone_ reading use X and _not_ the /dev/input/mice device? I
would be interested to hear from you!!!

thanks,

I don't see why you can't use /dev/input/mice - I have the same mouse 
setup as you and it works for me. Unless you have problematic hardware 
that is

Well, fwiw, I'll give you the config I have and that works for me (with 
irrelevant bits snipped out). Maybe it'll work for you too...

Section "ServerLayout"

   [snip synaptic config stuff]
        Option          "SendCoreEvents"        "true"

        Option          "Emulate3Buttons"
EndSection

It's been a long long time since I set this up but I believe the 
critical settings at the time were "CorePointer" and "AlwaysCore" in 
the ServerLayout

because the touchpad has to be configured differently to the usb mice,
otherwise things like "emulate3buttons" don't always work (on the
touchpad).  Also, I have different acceleration settings on different
mice, so I couldn't do that if they all used the same
"/dev/input/mice"...

Thanks.  I do indeed have CorePointer, and AlwaysCore for my various
mice - and it works, so I don't think changing the xorg.conf file will
fix it.

It's just when I unplug a working usb mouse, it won't work when I plug
it back in, UNLESS I switch to a console first. 

any other ideas?

So don't use /dev/input/mice for "all" mice, just for the USB mouse
that you plug in.  Use /dev/input/eventX for the synaptics trackpad.
Here is what I have for my two mouse entries in xorg.conf, and it
hotplugs USB mice perfectly:

Section "ServerLayout"

EndSection
Section "InputDevice"
        Identifier  "touchpad"
        Driver      "synaptics"

        Option      "AccelFactor" "0.3"
        Option      "UpDownScrolling" "On"
        Option      "LeftRightScrolling" "On"
        Option      "Buttons" "8"
        Option      "ZAxisMapping" "4 5"
EndSection
Section "InputDevice"
        Identifier  "usbmouse"
        Driver      "mouse"
        Option      "Protocol" "ExplorerPS/2"
        Option      "Device" "/dev/input/mice"
        Option      "Buttons" "8"
        Option      "ZAxisMapping" "4 5"
        Option      "SendCoreEvents" "On"
EndSection

I use a custom udev rule to make the "trackpad_evt" device, otherwise
my keyboard and trackpad event nodes get mixed up between event0 and
event1:

BUS=="input", KERNEL=="event*", SYSFS{phys}=="isa0060/serio1/input0",
NAME:="input/trackpad_evt", SYMLINK="input/%k"

Either this, or you have to wait for a version of X.org that truly
supports mouse hot plugging.

but I can't use /dev/input/mice.  I may not have been clear before, but
if I use /dev/input/mice, then the touchpad looses its Emulate3Buttons
when I use a real third button on a usb mouse...

Even if you don't use /dev/input/mice for the touchpad?

My touchpad does not seem to have a problem:
=========================================
Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "synaptics"
        Option      "Protocol" "SynPS/2"
        Option      "InputFashion" "Mouse"
        Option      "Device" "/dev/input/mice"
        Option       "Name" "SynPS/2 Synaptics TouchPad"
        Option       "SHMConfig" "on"
        Option       "Vendor" "0002"
        Option      "ZAxisMapping"      "4 5"
        Option      "Emulate3Buttons"   "True"
        Option      "Buttons"   "3"
EndSection
=========================================

On the other hand I have not tried (yet) a USB mouse to see if/how it will be 
picked up.  No problem with PS/2 mice though.  They are detected as soon as I 
plug them in.

No problem with my touchpad (HP Pavilion dv200z) and my Logitech USB 
mouse (even if I plug and unplug it).
