As of now, every distro I have tried with the xf86-input-synaptics driver has been not so good. Usually the middle click function does not work properly. And in every case I have had to download the code from upstream to get that bug rectified. And yes upstream is fantastic stuff, really rock solid. And yes, Arch even has a bugged version, so you most likely have to install the git version from AUR if you are having problems with multitouch.
Now we only need a good GUI configuration utility so we can tweak it to death and start sharing configs.
Hey, let’s pull this version and freeze it without testing anything – LOLbuntu and friends.
