Ubuntu: Unique problem facing installing Ubuntu 14.04 alongside preinstalled windows 8.1 on laptop lenovo z7080


I have recently buy lenovo z7080 laptop which has windows 8.1 pre-installed. I updated all the drivers and started to dual boot alongside windows with ubuntu 14.04LTS using dvd. I did enable legacy settings and give priority to legacy first. After when i entered into the installation i choose install ubuntu 14.04 alongside windows and after that give ubuntu about 750 gb and rest of about 250 gb to windows. But from entering the cd to start installation process my screen was shaking and linux could not find any wifi connection automatically and even when i manually tried.

After installation the the shake in the screen is still on and there is no internet connection(wifi). I did not tried lan connection.

While go back to windows through selecting UEFI from bios everything is ok there and size is altogether about 250 gb

Now how can i solve the ubuntu prob in screen shaking and auto internet connection??


The problem with the WiFi is because the version of ath10k drivers shipped with ubuntu don't yet have support for the new 168c:0041 wireless card in the laptop. This is fixed in the 4.3 kernel. There's a 4.3-rc3 build available in the kernel-ppa ppa at http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-rc3-unstable/
