I am facing unpleasant screen tearing when watching videos since some time, I am using Ubuntu 20.04.1 LTS on a Lenovo IdeaPad C340 laptop and I do not understand why it appeared (after some update I guess).
Here is the output of lspci -nn | egrep -i "3d|displa|vga":
00:02.0 VGA compatible controller [0300]: Intel Corporation UHD Graphics 620 (Whiskey Lake) [8086:3ea0] (rev 02)
I have tried already several things that I found on the internet, but unfortunately none of them did work for me, I have created a file /etc/X11/xorg.conf.d/20-intel.conf with following content :
Section "Device"
Identifier "Intel Graphics"
Driver "Intel"
Option "AccelMethod" "uxa"
Option "DRI" "3"
Option "TearFree" "true"
EndSection
And also a file /etc/X11/xorg.conf.d/20-intel-graphics.conf with following content:
Section "Module"
Load "dri3"
EndSection
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "DRI" "3"
EndSection
Following methods suggested respectively Screen Tearing on Ubuntu Xorg 20.04 with Intel Graphics and YouTube: How to Fix Intel Graphics Horizontal Lines Tearing Bug in Debian, Linux Mint and Ubuntu.
Any help would be appreciated!
