I am running Fedora 20 (Kernel 3.12.6) on a Lenovo Yoga 11S and I am using it with an external USB keyboard and mouse most of the time (since, at home, I have it located on a laptop stand in the "stand mode").
However, now I am on vacation, I don't have the mouse with me and I just recognized that the touchpad does not work anymore.
I know there are a lot of topics on the synaptics touchpad not working, but I can't seem to find the answer to my problem anywhere. Please forgive me if I missed it.
Here is what happened.
After using the "ambient light" F11 key on my HP laptop (Compaq nc8430), the touchpad was disabled and I couldn't get it to work.
Then I found this thread : "Synaptic touchpad on laptop not working".
