On a Yoga 2 Pro, using Kubuntu 14.04 with the latest 1.73 drivers, my touchpad fails to initialize as I have to blacklist the idea_pad-laptop module to enable wifi.
Removing idea_pad from the blacklist enables the touhpad, but wifi will not initialize.
I can't seem to manually revive wlan without removing the ideapad-laptop module:
Failed manual attempts at reviving the wlan were as follows:
sudo rmmod -f ideapad-laptop
sudo rfkill unblock all
sudo ifconfig wlan0 up
sudo service network-manager restart
shows that wlan0 is "UP BROADCAST..."
Looks like this issue can be resolved as per this bug report, https://bugzilla.redhat.com/show_bug.cgi?id=1021036, but patch has yet to land in the kernel.
I sure wish the manufactures would put a little more time in testing their products with Linux and requesting Linux compatibility from their component vendors.
