Description Sergey Novak 2011-03-21 04:30:19 UTC

I use multiseat (doubleheaded) configuration with two mouse sections in xorg.conf:

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/mouse0"
        Option      "ZAxisMapping" "4 5"   ### Wheel mouse
EndSection
Section "InputDevice"
        Identifier  "Mouse1"
        Driver      "mouse"
        Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/mouse1"
        Option      "ZAxisMapping" "4 5"   ### Wheel mouse
EndSection

Uname:
$ uname -a
Linux goodyhome 2.6.38-gentoo #3 SMP Sun Mar 20 15:12:04 EET 2011 x86_64 AMD Athlon(tm) II X2 215 Processor AuthenticAMD GNU/Linux

$ X -version

        to make sure that you have the latest version.


Regardless of kernel and xorg versions mouse input is mixed: any event (movements, clicks, scrolls) of two mouse devices is sent to both X process.


Reproducible: Always

Steps to Reproduce:
1. Update to x11-drivers/xf86-input-mouse-1.7.0 
2. Restart X

Actual Results:  
Mouse input is mixed. I can use any of two mouse devices to control both seats on dualheaded station. I can't control only one seat using mouse: events are sent to both seats.

Expected Results:  
Every mouse device should send data to it's own X server (described in xorg.conf sections). Each user on dualheaded station should use own mouse.


Downgrading to x11-drivers/xf86-input-mouse-1.6.0 fixes the problem.

Here is my xorg.conf:

Comment 1 Tolga Dalman 2011-03-22 11:59:15 UTC

Have you tried to use the evdev driver for mouse input ?

Comment 2 Sergey Novak 2011-03-24 13:26:30 UTC

(In reply to comment #1)
> Have you tried to use the evdev driver for mouse input ?

I did try only specified configuration.
I can make some experiments if it can help.
Tell me what to do.

Comment 3 Balint Dobai-Pataky 2012-03-17 18:58:33 UTC

This is how mine looks:
xorg.conf
Section "InputDevice"
        Identifier  "third_mouse"
        Driver      "evdev"
#       Driver          "mouse"
        Option      "Protocol" "imPS/2"
        Option      "Device" "/etc/X11/third_mouse"
        Option      "ZAxisMapping" "4 5 6 7"
EndSection

while
#ls -l /etc/X11/third_mouse
lrwxrwxrwx 1 root root 63 Nov 25 17:48 /etc/X11/third_mouse -> /dev/input/by-path/pci-0000:00:1a.0-usb-0:1.3.2:1.0-event-mouse

Hope it helps.

I suspect this is (1) long since fixed, or (2) a configuration error. Regardless, using xf86-input-libinput is the recommended path today.
