I recently made the switch from Windows 10 too Ubuntu Mate (v18.04) and really like it. However, I just can't get rid of a screen flickering problem. It happens about 50% of the time and affects the left hand side of the screen. The problem didn't exist on Windows. I also tried Ubuntu Desktop (v18.04), and had the exact same screen flickering problem there too.
I've searched google extensively and found lots of people experiencing the same problem. However, no one ever seems to provide a definitive answer to this problem. A common solution proposed is to create a file called 20-intel.conf at /usr/share/X11/xorg.conf.d/
I have tried this with a few different contents such as:
Identifier "Intel Graphics"
Option "AccelMethod" "sna"
Option "TearFree" "true"
Option "DRI" "3"
However, none of the proposed solutions work for me and hasn't worked for many others. Here is a list of examples where this same issue seems to be happening:
I love Ubuntu and would love to resolve this issue so if anyone can help me fix it, I'd be very grateful :)
