For 3 months or so my MBP was fine under Ubuntu. About a month ago (I think after an update), my screen started flickering whenever there is a screen refresh. The flickering varies from slight jitter to split-second screen tearing. It is hard to work with.

I found that if I attach an external monitor via HDMI the screen flicker stops on both monitors.

MacBook Pro (Retina, 15-inch, Mid 2015) Graphics: Intel Iris Pro 1536 MB

I tried getting the appropriate 16.04 Intel drivers from 01.org, but I still have the same problem. Edit from comment: If I boot or come out of suspend with the power cable disconnected, the flicker doesn't happen. I can then plug in the power cable and there is no flicker. Also, this problem does not happen under OSX/MacOS

  • This is my problem too. Works fine with connected displays, and often if it's plugged in, but flickers constantly. Doing something like running TuxRacer or opening a Twitch stream seems to temporarily abate it but is of course horrible for battery life. – Anna Mar 27 '17 at 18:17
  • Try adding i915.enable_fbc=0 to the boot parameters in GRUB – Android Dev Mar 30 '17 at 2:02
  • it's a common problem. The answer is not hard to find (happended to me last year, took 20 mins of research to fix). – Yves Mar 30 '17 at 22:26
  • Can you duplicate the problem when booted from live media? – Elder Geek Mar 31 '17 at 14:19

Try addingacpi_osi= to boot parameters. Installing the package xbacklight might also help
