When I first upgraded paldo it asked me to remove the synaptic package but the xorg driver is still there and it loads without any problem. Since then the touchpad didn't worked anymore... anyone has the same problem?

EDIT - A correction: the kernel detect and loads the Synaptic driver but Xorg says it can't detect it. The distro's xorg.conf doesn't provide any specification about input devices so I'm gonna try to add it. This problem should affect any laptop!

I solved the problem following this guide: http://gentoo-wiki.com/Synaptics_Touchpad. It's very uncommon to use a Xorg configuration with no input devices specified...

On my laptop it still works. just checked with latest kernel in branch testing

It seems like X.org tries to detect the device but it isn't able to. I had to manually add the configuration in /etc/X11/xorg.conf to make my touchpad work. Maybe it's a hardware-specific bug...

we always using the newest x.org. ours normally has hotplug so it isn't needed to do it the old way ... but if it helps you, ok.
