scroll wheel emulation not working in Kubuntu 8.10 Beta

As far as I know, this is because X now uses hal to configure input devices.

You can solve this by copying the attached file to /etc/hal/fdi/policy/mouse-wheel.fdi

This only enabled up/down scrolling. If you want left/right, you have to remove the <!-- and --> lines (but not the lines between these two).

 Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

Yes. Thanks for the policy file. Yet while the hal policy enables trackpoint scrolling after startup, it still does not work after standby-resume. This is the most annoying unsolved problem in my ubuntu experience. As a workaround I can unload and reload the psmouse module, which is a little unsatisfactory, especially if people are around to notice that "You need to type cryptic commands in the console to make Linux work".

I now made a script that reloads psmouse, as described in https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/282387/comments/67.
Works for me, seems to be more "upgradable" than patching evdev.
I hope the bug in evdev will be fixed somewhen, but for now this report can be closed.

This bug is still present on a freshly installed system with Ubuntu 9.04 (Jaunty). I am using the x86_64 bit desktop edition. Puting the .fdi file into the policy folder fixes the issue either after a restart or by issuing the commands:

sudo modprobe -r psmouse
sudo modprobe psmouse

I am using a X61 Thinkpad with a trackpoint and this bug is quite annoying, luckily its one of the easier to fix.

I just tested with the Kubuntu Karmic Koala beta version on a Thinkpad T400, and emulated scrollwheel still doesn't work. And as far as I can tell, there is no way to enable it through system settings.

Installing the Hal policy I've previously attached, fixed the problem for me.

The final release of Karmic Koala still exhibits this behaviour.
