tapping on touchpad does not work anymore

Ever since I upgrade my ancient Latitude laptop to 2.6.x, I can't tap on the touchpad to left-click anymore. Is this a known issue? I am running 2.6.1 now.

Thanks,

I experienced the same, also with a Latitude....

If you need taps you will either have to install a native XFree Synaptics driver (also provides scrolling, multi-finger and corner taps, etc) or pass psmouse_proto=bare to psmouse module (or psmouse.psmouse_proto=bare if compiled in). The name will be changed to psmouse.proto in later releases.
