Bug 186874 – xorg does not hadle any more 2 axis mice

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description DEMAINE Benoît-Pierre, aka DoubleHP 2007-07-28 10:25:57 UTC]

End of june, I set up 2 axis wheel mouse configuration, and it worked for 2 weeks. After some system updates, it stopped working. Initial report was made in forums:
http://forums.gentoo.org/viewtopic.php?p=4152236#4152236

Facts are:
- I have a Logitech RX1000
- configured as explained on http://imaginux.com/roadtolinux/dotclear/index.php?2007/04/24/196-logitech-lx3 
- it worked for about 2 weeks
- stoped working without changing anything in Xorg conf, but seems to be after xorg re-emerging
- when I cat /dev/input/by-id/usb-Logitech_USB_Optical_Mouse-event-mouse it produces habitual garbage on scree, in the 4 possible ways to push the wheeh (I mean: mouse works fine, and kernel driver can /still/ handle both axes).
- xev do report events on vertical scrolling, but not on horizontal for this mouse
- all always worked and still works fine with my home made PS2 touchpad (home made after disassembling a laptop) (always worked, and still works => xorg still hadles horizontal events ).

My personnal conclusion is that ... driver for USB mouse broke by the mean time.

I esync every night, and emerge -DaNuv world twice a week. I cant give breaking day because I dont use this feature daily.

I could give actual xorg.log, but I am not sure it would be revealant since I did not keep one from the time it used to work. I ll try if this BTS allows me to atatch such big files.

In fact, syntax of xorg.conf changed; here is the minimal conf section to get it working:

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "evdev"
        Option          "CorePointer"
        Option          "Name"  "Logitech USB Optical Mouse"   
        Option          "HWHEELRelativeAxisButtons" "7 6"
EndSection

Here is my personnal setting that also works very well:

Section "InputDevice"
        Identifier      "USB Mouse"
        Driver          "evdev"
        Option          "Emulate3Buttons"       "true"  #optional
        Option          "Name"  "Logitech USB Optical Mouse"
        Option          "ZAxisMapping"          "4 5"   #optional
        Option          "HWHEELRelativeAxisButtons"     "7 6"
EndSection 

Closing INVALID.

Fix has been given on forum exactly while I was typing this report. Took a few minutes to check it.
