xf86-input-synaptics 99.1-1

The update to xf86-input-synaptics 99.1-1 breaks something, and no longer recognises tapping or scrolling.

I was unable to diagnose the problem (I'm in English class =P) so I just downgraded to 15.2-1.

For some reason the update was in the extra repositories, instead of testing..

Re: xf86-input-synaptics 99.1-1

It's related to the new xorg that just moved from testing into extra, from what I can see it's an update that requires some manual tweaking to get everything working. There's lots of threads already with people trying to deal with the issues. I'd give you more specific advice, but after seeing the rash of questions dealing with this update I decided to put off upgrading xorg until after my exam next week.

Re: xf86-input-synaptics 99.1-1

I had the same problem. I found the answer in the wiki.

New xorg disables sidescrolling and tapping by default.

Remove whatever you have in your xorg.conf about synaptics and add this to it. I have the two lines relating to two finger scrolling commented out because you are probbably not used to two finger scrolling if you want sidescrolling. Uncomment them if you see fit.

EDIT: Oh yeah, this works for me, but this may not be the smartest way to do it. This post describes an alternate method:

I'm too lazy to do it, but this method is better since it works with the new hotplug feature in xorg. You could read the wiki page about it if you want.
