I am currently using Ubuntu 16.04 and when I look my system details my gpu is named as Intel® 965GM but if I install Ubuntu 20.04 it is named as Intel® 965GM (CL). System ui and google chrome is really smooth with drivers of 16.04 but not with 20.04. I tried to install unity desktop to 20.04 but again chrome is not as smooth as 16.04. What is the difference between these two version of drivers? If I figure it out I can finally upgrade to 20.04. Thanks.
I edited 20-intel.conf file (located at /etc/X11/xorg.conf.d/) and added those functions;
Section "Device" Identifier "Intel Graphics" Driver "Intel” Option "DRI" "3" Option "TearFree" "true" EndSection
After that you need to edit /etc/environment file and add;
Save files than reboot your machine.
