Problem

I updated to Ubuntu 18.04, and I'm facing tremendous screen flickering/shaking/distorting at random times for random duration. The display is working fine on another Monitor that I have.

I was observing screen flickering but not shaking. I had to edit my monitor config and change the framerate. By default mine was set to 60.169086456298828.

open terminal and run the following:

gedit ~/.config/monitors.xml

edit this line:

<rate>60.1690864562988</rate>

set it to be lower than 60 as mentioned by 4levels, I used 59.96.

I just deactivate the compositor from settings/GUI. I'm new to Linux and stuff but this work for me, I'm using Kubuntu on a very old system/pc.

I faced the same problem when I updated my Ubuntu 16.04 to 18.04 LTS. The 18.04 is running by default on linux kernel v4.15 while new kernel version v5.0 and above are available. Try to change the kernel version using: https://kernel.ubuntu.com/~kernel-ppa/mainline/

Download packages according to your requirements, i.e., generic/low latency and install.

This solved my problem. Hope this helps!

I was having the same problem, and disabling my compositor worked too. compton was glitching text on my screen. Disabled it and all is well.

I had this problem with Ubuntu 20.04 and Virtualbox 6.1.

I reinstalled it, this time by selecting the correct type of OS in Virtualbox in the first step. It works well now.
