Hello I have a Zenbook Pro UX501VW and installed Ubuntu 16.04.1. I installed the GTX drivers for the crazy fans.

I saw that by installing kernel 4.3.5 it would fix the trackpad so I downloaded all the files and installed them with sudo dpkg -i *.deb And removed the old ones with sudo apt-get remove linux-image-4.4.0-21* linux-headers-4.4.0*.

I rebooted and by typing uname -r the output is 4.4.0-38-generic... Output of dpkg -l | grep linux-image :

EDIT :

  • how can i downgrade the kernel to 4.3.5 – M. Heisy Sep 27 '16 at 12:15
  • Please add the output of the command dpkg -l | grep linux-image to your message. Have you run update-grub? – Melebius Sep 27 '16 at 12:25

    If you're having a black screen when booting the 4.3.5 kernel, then you simply can't boot it. Also, 4.3.5 doesn't have proper Skylake support if you have a Skylake CPU. I would try newer kernels. If you must, compile your own kernel – negusp Sep 27 '16 at 13:38
