I have an older notebook with ATI. (Actually I gave it to a friend) Recently I updated to OS is ubuntu 16.04 from 12.x.
glxgears looks good, but after installing later firefox when watching some YT it slows down and video breaks. even lowering quality to 360 is not very good. I installed older version of FF and it was much better but still not good. Do you have any idea how I can improve this? thanks
