The problem is not only with videos. Even catting a file or opening vi updates the screen slowly, almost line by line left to right. The only time when above problem doesn't trigger is, if I do 'xrandr --same-as' to have hdmi a mirror of eDP. I like to use a vertical hdmi monitor, so above option isn't suitable for my usage. In fact, with hdmi completely out of the picture, if I do 'xrandr --rotate' on eDP screen, just to see what happens, the slow refresh occurs on eDP also. Does it mean the acceleration works only in certain mode(s)? So far intel-UXA is the only combination that has somewhat worked. *-none starts but is not usable. intel-SNA doesn't work, modestting/wsfb with defaults don't even start. -- Mayuresh
