I've just got a Lenovo Y70 Touch laptop.

Problem: The laptop screen is vibrating, (flickering? shaking? not sure what the best word for it) as if refresh rate was the problem. (17.3" 1920x1080) External monitor through HDMI working OK, no problem.

The problem started from the very beginning, when I booted from the Ubuntu 14.04 DVD.

No problems under Windows 7 and 8.1.

  • Disabling the kernel module for the intel driver solved the flicker-problem, but produced two more problems: 1. BRIGHTNESS CANNOT BE ADJUSTED, 2. THE LAPTOP IS GETTING HOT – JNE Oct 5 '14 at 17:44
  • Why is it ok on an external monitor and why is not ok on the laptop screen? – JNE Oct 5 '14 at 17:47
  • Could it be the touch module? Does it register as a mouse or touchpad perhaps? – Dr. Tyrell Oct 7 '14 at 4:30
  • Could you please tell me what to look at? – JNE Oct 7 '14 at 8:54

    @JNE: Please edit your question if you have something to add. It's much more difficult to find all the relevant info scattered in the comments. This way you can also keep the line breaks of program output and log files. – David Foerster Nov 14 '14 at 4:02

I got the same issue with you, after numerous installs I could not fix the issue, but then i tried installing a later kernel, more specific 3.18rc3. For me this fixed the problem, the one thing that i can not do is install the nvidia drivers but this is not an issue for me.

Get the .deb files from here http://linuxg.net/how-to-install-kernel-3-18-rc3-on-ubuntu-14-10-ubuntu-14-04-and-derivatives/

I hope this helps

  • Upgrading to kernel 3.18 solved the problem for me too! Thanks. Why did someone downvote this answer??? Upvoted. (Neither kernel 3.13 nor 3.16 worked.) – KajMagnus Mar 5 '15 at 20:35
