HP Pavilion X2 worked almost fine on Ubuntu 13.10. Touchpad (stop working after sometime), Touch Screen. WebCam, WiFI worked fine.
On upgrading to Ubuntu 14.04, everything above mentioned stopped working.
Even external USB mouse fail to work. Never expected such a situation.
Similar thing I heard from other with different hardware.
Is there issue of drivers with Ubuntu 14.04 or Is there something I missed?
How to manage it to bring to life. It does not have Ethernet card. Only WiFI is there.
