Kernel 2.6, XFree86, EmulateWheel

This is the contents of the pointer section of my XF86Config-4's pointer section:

Section "InputDevice"
        Identifier  "PS/2 Mouse"
        Driver "mouse"
        Option "Protocol" "MouseManPlusPS/2"
        Option "Device" "/dev/input/mice"
        #Option "Device" "/dev/psaux"
        Option "Buttons" "6"
        Option "ZAxisMapping" "5 6"
        Option "EmulateWheel" "on"
        Option "EmulateWheelButton" "4"
EndSection

(I've tried both Device options above, same results)

I have a Logitech Cordless Trackman, four button, one ball. Under kernel 2.4, I get scrolling (EmulateWheel) behavior if I hold down the fourth button and roll the ball back and forth. This is the behavior I want, of course.

However, under kernel 2.6 (currently 2.6.5, but I tried it with 2.6.1 and 2.6.0-test9 as well), the behavior is not the same. Instead, my fourth button is acting the same as my center button (which I generally use for copy/paste, and open new link in firefox).

xev confirms this:

ButtonPress event, serial 27, synthetic NO, window 0x2400001,
    root 0x95, subw 0x0, time 39216488, (151,172), root:(470,507),
    state 0x0, button 2, same_screen YES

ButtonRelease event, serial 27, synthetic NO, window 0x2400001,
    root 0x95, subw 0x0, time 39216591, (151,172), root:(470,507),
    state 0x200, button 2, same_screen YES

ButtonPress event, serial 27, synthetic NO, window 0x2400001,
    root 0x95, subw 0x0, time 39217191, (151,172), root:(470,507),
    state 0x0, button 2, same_screen YES

ButtonRelease event, serial 27, synthetic NO, window 0x2400001,
    root 0x95, subw 0x0, time 39217338, (151,172), root:(470,507),
    state 0x200, button 2, same_screen YES

The thing is, I can't tell if its a kernel configuration issue, a bug in the kernel, or a misconfiguration in XF86Config-4. It seems very very odd to me that it worked in 2.4 and not in 2.6. Perhaps I need to support some sort of legacy mouse driver? :?

Any other ideas? I don't know what else to test to solve this. I don't like using pg-up/pg-down for scrolling all that much. And I don't really want to go back to 2.4 kernel now either, its time to embrace the future. I've been running 2.4 since 2.6 came out so I could ignore this issue, but that's not a very interesting solution. smile

Re: Kernel 2.6, XFree86, EmulateWheel

I had problems with mouse under 2.6. kernel ....this works for me:

Section "InputDevice"
        Identifier  "PS/2 Mouse"
        Driver      "mouse"
        Option      "Protocol" "imps/2"
Option          "ZAxisMapping"          "4 5"
        Option      "Device" "/dev/misc/psaux"
        Option      "Emulate3Buttons" "true"
        Option      "Emulate3Timeout" "70"
        Option      "SendCoreEvents"  "true"
EndSection

Re: Kernel 2.6, XFree86, EmulateWheel

I tried adding the SendCoreEvents line and using /dev/misc/psaux, but it didn't help. I think that either the kernel or the X mouse driver (probably the kernel, since the driver worked with 2.4) isn't recognizing the button 4 press; it thinks its a button 2 press.

I changed it so that my EmulateWheelButton is button 2; now its recognizing wheel movements on both buttons. This cheats me out of one button!!!!

This PS/2 mouse is actually a USB mouse with a PS/2 adapter... does anybody think it would work better with USB?  What would be the XF86Config device for a USB mouse?

My cordless mouse is USB connected via PS/2 and it works but if you want to try USB direct then you'll have some fun with Hotplug..maybe it will just work tongue

Re: Kernel 2.6, XFree86, EmulateWheel

I think k 2.6 has some strange relation with pointer device. I dunno if is due to k2.6 arch linux configuration or not.
On my klaptop I have archlinux, since I upgraded the kernel to 2.6 the toucpad works even if not configured under X (I use an usb mouse), in fact if I start x under 2.4 the touchpad does not work.

Re: Kernel 2.6, XFree86, EmulateWheel

I've had this problem under knoppix as well, so I don't tihnk its arch specific.

My mouse, connected via USB is working fine now, using protocol MouseManPlusPS/2, PS/2, or auto. That's strange, right?

But the scrolling still doesn't work. All configurations are recognizing a button 4 click as a button 2 under xev. I think its kernel related. sad

Maybe I should report a bug, but I can't seem to get enough information to file a useful bug report...

Re: Kernel 2.6, XFree86, EmulateWheel

I checked the bug reports at bugzilla.kernel.org and found some similar issues, but no decent solutions.  I sent an e-mail to the kernel mailing list. I feel cheap, those guys are way above me to be questioning them. wink

A lot of bugs re logitech pointers...

Re: Kernel 2.6, XFree86, EmulateWheel

Well, this morning the issue was resolved after I rebooted. I have no idea what happened.  This is the working XF86Config-4 Mouse section:


Section "InputDevice"
        Identifier  "Mouse"
        Driver "mouse"
        Option "Protocol" "ExplorerPS/2"
        #Option "Protocol" "MouseManPlusPS/2"
        Option "Device" "/dev/input/mouse0"
        Option "Buttons" "6"
        Option "ZAxisMapping" "5 6"
        Option "Emulate3Buttons" "off"
        Option "EmulateWheel" "on"
        Option "EmulateWheelButton" "4"
EndSection

I don't know if that was all I did that solved the prob or if there was something else that I just can't find the difference.  I'm surprised if it was just an X issue, but...

So anyway, if anybody needs that info, there your are. I'm satisfied with 2.6 kernel now. smile
