[Suggestion] Enable TrackPoint middle scroll by default

[Thomas Calvert]

Binary package hint: xinput

Hi, this is not a bug but I'm not sure where to post it...

My suggestion is simply to have the middle button on TrackPoint devices (found on most Thinkpad laptops) scroll the page by default. This can be simply achieved by running this script :

for XINPUT_ID in `xinput list | grep TrackPoint | cut -d= -f2 | cut -d\[ -f1`; do
 xinput set-int-prop $XINPUT_ID "Evdev Wheel Emulation" 8 1
 xinput set-int-prop $XINPUT_ID "Evdev Wheel Emulation Button" 8 2
 xinput set-int-prop $XINPUT_ID "Evdev Wheel Emulation Timeout" 16 200
done

There may be a better way in the package, but I don't know about it. The change seems to persist across reboots, however the ID of a device sometimes changes.

Otherwise maybe an option in Preferences > Mouse that may allow other behaviours... But by default it would be nice to have it do something!

Best,
- Thomas

Hi thomas-calvert,

Please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you're using a custom /etc/X11/xorg.conf please attach that as well.

After a few weeks' usage, I find that I practically always have to re-run the script after rebooting the computer (ID seems to change between #9 and #10), however not after suspend.
