Problem description
I have two monitors with Ubuntu 20.04:
- Primary DELL 24" in landscape mode connected as DP-1
- Secondary BENQ 24" in portrait mode connected as HDMI-1, however it is in fact DVI-D - HDMI connection. Also for some reason Ubuntu display manager in GUI views it like BENQ 22" which is wrong.
So I have screen tearing problem, especially in the browsers while scrolling. On the vertical monitor I have vertical tearing while scrolling and on landscape monitor I have somewhat diagonal tearing while scrolling.
What I've tried to do:
I've tried to create /etc/X11/xorg.conf.d/
directory and put this in 20-intel.conf
:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"
Option "DRI" "3"
EndSection
After reboot I had my vertical monitor turn back to horizontal and Chrome and Firefox did not render their pages properly. Every click inside their windows seemingly lead to nothing, but if maximized/minimized the rendering was correct. After I tried to make it vertical back in Ubuntu display manager GUI, xorg (? I'm not sure, I'm a noob) crashed.
If I do this without "DRI" "3"
option then after reboot both monitors have some ugly artifacts.
