EmulateWheelButton doesn't work anymore on my Thinkpad X61s

[Muelli]

I just upgrade to intrepid (by accident) and now I can't scroll anymore.

I think I hacked scrolling support into my xorg conf with the following lines:

Section "InputDevice"
 Identifier "Configured Mouse"
 Driver "mouse"
 Option "CorePointer"
 Option "Device" "/dev/input/mice"
 Option "Protocol" "ImPS/2"
 Option "YAxisMapping" "4 5"
 Option "XAxisMapping" "6 7"
 Option "ZAxisMapping" "4 5"
 Option "Emulate3Buttons" "true"
 Option "EmulateWheel" "on"
 Option "EmulateWheelButton" "2"
EndSection

They are still present but I can't scroll anymore by holding the middle mouse button and move the touch-stick up and down.

Please let me know if I can provide more information.

Yeah, there are ignored now. I think that we need to use .fdi-files now.
I tried to make a file /etc/hal/fdi/policy/mouse-wheel with

<!-- http://mvogt.wordpress.com/2008/08/15/xorg-evdev-and-emulatewheel/ -->
<match key="info.product" string="TPPS/2 IBM TrackPoint">
 <merge key="input.x11_options.EmulateWheel" type="string">true</merge>
 <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
 <merge key="input.x11_options.ZAxsisMapping" type="string">4 5</merge>
 <merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
</match>

but it did not work for me either.

Hm. Either way, there should be a migration path. At least a warning somewhere.

Do you have a link to the official documentation of the points you are mentioning (like that the directives are ignored and that fdi files should be used instead)?

[Michael Fritscher (michael-fritscher)]

the fact of ignoring stands on the announcment site of the alpha4 under caveats ( http://www.ubuntu.com/testing/intrepid/alpha4 ), On http://mvogt.wordpress.com/2008/08/15/xorg-evdev-and-emulatewheel/ I read about the fdi thing. There is a gui mentioned, too, which would be very nice, as there are lots of different mouse types (normal mouse with 2 to 5 buttons and 2 to 4 dimensions (mouse wheels), touchpad, touchstick, trackball, tablets, jousticks etc.)

Well, since xorg 7.4 and it's input-hotplugging goodness the InputDevices-sections of the xorg.conf-file do not have any effect on your input-hardware. Instead, evdev does this using the hal's fdi-configfiles located in /etc/hal/fdi . Unfortunately, the shipped evdev-version is too old making you have to get the newest. Fortunately, there is a launchpad repo serving this deb. Just add a new file to /etc/apt/sources.list.d/ called evdev.list (or whatever you like) und put in the following line:
 deb http://ppa.launchpad.net/mvo/ubuntu intrepid main
After an aptitude update and dist-upgrade you should have the newest evdev-version. Combined with the new fdi-file mentioned by Michael Fritscher above the scrolling-feature should work again. Don't forget to make sure that the string-value of the first match-tag (where key="info.product") is correct. You can check that using "dmesg | input". Watch out for a line that looks like this: input: TPPS/2 IBM TrackPoint as /class/input/input7

that's it! Now it should work :).
cheers

Ah, I forgot to mention that this should not be considered as a bug but as an unimplemented feature. In fact, evdev in intrepid alpha 5 is just outdated (which I guess is going to be fixed soon). Plus maybe it would be a nice thing to have this fdi-profile shipped with the main distribution :).

Well, looking at this repository, I can only find an older version version xserver-xorg-input-evdev:

I was about to report this issue when i found this bug and another at https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/251408 It seems they are for the same subject and one should be marked a duplicate of the other.

Is there any chance this will get fixed in intrepid. My guess is unlikely as the beta period has begun and it technically may be considered a new feature.

Should I then go ahead and edit my xorg.conf as I have don in the past to fix this? I am warry of doing this because it will hamper even if only slightly my ability to test a clean intrepid install.
