ALPS touchpad: unable to get scrolling to work

somedrew · 2007-05-14 13:04:15

I've been unsuccessfully trying to get vertical scrolling working for my Alps touchpad and have run out of ideas. I've followed instructions on both Arch'sand Gentoo's wikis and have tried every combination of device and protocol settings for the touchpad that I can think of in xorg.conf (including setting proper borders from synclient's output). The driver seems to be loading and functioning as the sensitivity changes I've put in xorg.conf are taking effect...just a no go for scrolling.

Is there something I'm missing here, or does anyone have any ideas? Thanks a lot for any input!

event6 seems to be the proper device as it's the only one out of which I get a response from the touchpad from a 'cat /dev/input/...'. However, if I use mouse2 or ts2 the trackpad still functions and my sensitivity setting changes do take effect.

Thanks for the help! Turned out that my edge's were way too big.
