running Xconfigurator or mouseconfig doesnt setup 3 button emulation for two button ps2 mouse. Seen on a dell inspiron 3500, with a ps2 2 button touch pad. adding: Option "ChordMiddle" "1" Option "Emulate3Buttons" "1" Seems to make it work. Sorry if this dupes, the original didnt seem to stick.
Ehm, it works fine for me if you select emulate 3 buttons, this isn't however done automaticly for 2 button mice like anaconda does, I'll add a seperate bug for that.
